Human activity to blame for virus spread

PARIS — Diseases such as the COVID-19 pandemic sweeping the globe could become more common as human activity destroys habitats and forces disease-carrying wild animals into ever-closer proximity with us, a major study showed on Wednesday.

Illegal poaching, mechanised farming and increasingly urbanised lifestyles have all led to mass biodiversity loss in recent decades, devastating populations of wild animals and increasing the abundance of domesticated livestock.

Around 70 per cent of human pathogens are zoonotic, meaning they at some point make the leap from animals to humans as with COVID-19.

US-based researchers looked at more than 140 viruses known to have been transmitted from animals to humans, and cross-referenced them with the IUCN's Red List of endangered species.

They found that domesticated animals, primates, bats and rats carried the most zoonotic viruses — around 75 per cent.

But they also concluded that the risk of spillover from animal to human populations was highest when a species is threatened by over-consumption and habitat loss.

"Our data highlight how exploitation of wildlife and destruction of natural habitat in particular, underlie disease spillover events, putting us at risk for emerging infectious diseases," said Christine Johnson, from the University of California's School of Veterinary Medicine, lead author of the research.

Last year the United Nations panel on biodiversity warned that up to one million species faced extinction as a result of human activity.

The landmark assessment showed that 75 per cent of land and 40 per cent of oceans on Earth have already been severely degraded by mankind

Deforestation, in particular, is placing increasing pressure on wild mammals, which struggle to adapt to dwindling habitats.

And as we encroach further on their territory, wild animals are being forced into increasing contact with humans, heightening the risk of another COVID-19.

"We alter the landscape through deforestation, conversion of land for growing crops or raising livestock, or building up communities," Johnson told AFP.

"This also increases the frequency and intensity of contact between humans and wildlife — creating the perfect conditions for virus spillover."

 

Trade ban urged

 

Scientists are still trying to pin down the species that passed COVID-19 to humans — suspects include bats and pangolins, both considered delicacies in China, where the outbreak emerged.

Conservationists have called for a global ban on wildlife trading in the wake of the pandemic and China has prohibited the consumption of wild animals.

Greenpeace on Wednesday urged the European Union to push for a worldwide ban "in order to protect public health and biodiversity across the globe".

But COVID-19 has also seen crucial UN biodiversity talks postponed and several indigenous groups are reporting greater encroachment from illegal miners and poachers into tropical forests.

The study, published in the journal Proceedings of the Royal Society B, also showed the prevalence of zoonotic disease in animals that are mass-produced for agriculture.

"Once we move past this public health emergency, we hope policy makers can focus on pandemic preparedness and prevention of zoonotic disease risk, especially when developing environmental, land management, and animal resource policies," said Johnson.

Pandas use lockdown privacy to mate after a decade of trying

HONG KONG — Stuck at home with no visitors and not much else to do, a pair of pandas in Hong Kong finally decided to give mating a go after a decade of dodging the issue.

Like half the planet, Ying Ying and Le Le have only really had each other for company since coronavirus-caused lockdowns shut off the flow of guests to their theme park pad.

And like couples everywhere, they've been making the best of the time on their own.

"Since Ying Ying and Le Le's arrival in Hong Kong in 2007 and attempts at natural mating since 2010, they unfortunately have yet to succeed until this year upon years of trial and learning," said Ocean Park conservation official Michael Boos.

The park released photos of the pair embracing in an enclosure uncharacteristically free from prying eyes and camera phones.

Pandas are notoriously bad at reproducing, especially in captivity.

But vets had their hopes up when the monochromatic lovers started showing an interest in each other during the short spring mating season.

For those who knew where to look for the tell-tale signs, ursine love was in the air.

"Since late March, Ying Ying began spending more time playing in the water, while Le Le has been leaving scent-markings around his habitat and searching the area for Ying Ying's scent," the park said.

"Such behaviours are consistent with those common during breeding season, which occurs once every year between March to May," it added.

Experts will now monitor Ying Ying for signs of pregnancy, but it may be quite some wait as the gestation period for giant pandas ranges from 72 to 324 days.

The park said confirmation of pregnancy can only be detected by an ultrasound scan some 14 to 17 days before birth.

But Ying Ying might exhibit hormonal fluctuations and behavioural changes as early as June if fertilisation has occurred.

The announcement was a rare bit of good news as Hong Kong reels under a recession and movement restrictions caused by the coronavirus.

Ocean Park, which is earmarked for a HK$10.6 billion ($1.4 billion) bailout from the city government, has been shuttered since late January because of the pandemic.

Many Facebook commenters speculated that the absence of crowds might have boosted Ying Ying and Le Le's confidence.

"It's a good time to make baby bear when you are on holiday and have no pressure," wrote Janet Mok.

Chan Fong added: "It's no pressure when no one is watching."

 

Coronavirus patients can benefit from blood of the recovered

For 10 patients severely ill with the new coronavirus, a single dose of antibodies drawn from the blood of people who had recovered from COVID-19 appeared to save lives, shorten the duration of symptoms, improve oxygen levels and speed up viral clearance, newly published research reports.

The preliminary findings emerged from a “pilot study” published Monday in the journal PNAS, the Proceedings of the National Academies of Sciences. Conducted at three hospitals in China, it promised only to suggest the benefits of harvesting immune antibodies from recovered people (also called convalescent plasma) and administering it to people battling a severe case of COVID-19.

But its findings offer hope that a therapy with a long history and a simple premise could be a powerful treatment for COVID-19 patients fighting for breath. In the early 20th century, doctors transferred the bloodborne antibodies of patients who had recovered from polio, measles, mumps and flu to those who were in still in the grips of those infections. Armed with a veteran infectee’s immune memory of the virus, patients getting convalescent plasma appeared to recover more quickly and completely than patients who did not get the treatment, physicians observed.

With a vaccine at least a year away and no clear treatments available for COVID-19, the US Food and Drug Administration on March 24 approved the use of such therapy as an experimental treatment in clinical trials and for critical patients without other options.

The new pilot study signalled that the therapy will not disappoint. One patient, a 46-year-old man with high blood pressure who showed up at a hospital with fever, cough, shortness of breath and chest pain, was relying on a ventilator to push oxygen into his lungs, and still his blood-oxygen level was a dismal 86 per cent. (Normal readings range from 95 per cent to 100 per cent.)

Eleven days after his first symptoms had appeared, the patient received an infusion of so-called convalescent plasma. On day 12, his blood tested negative for infection with the SARS-CoV-2 virus. His body’s inflammation level turned sharply down. And his blood-oxygen level had climbed to 90 per cent. The next day, he was weaned off of the mechanical ventilation that had breathed for him for three days.

In addition to his lungs, the patient’s immune system and liver function, both on the ropes at the height of his illness, were steadily returning to normal four days after he got the plasma antibody infusion.

For a 49-year-old woman with no underlying illnesses, COVID-19 infection quickly progressed to shortness of breath and hospital admission. By day seven after the onset of her symptoms, her chest X-ray had shown the hallmark opacity of ground glass and she had build-ups of fluids or proteins — infiltrates — scattered throughout both lungs. On day 10 following the onset of symptoms, she got an infusion of convalescent plasma. By day 12, she had cleared the virus from her system and her chest X-ray was clearing markedly.

A 50-year-old male with “massive infiltrates” in both lungs showed a gradual clearing of his lungs and tested negative for infection 25 days after his first symptoms appeared.

In all 10 patients, the symptoms that had driven them to seek emergency care had either disappeared or largely improved within one to three days of their receiving a transfusion of antibodies from a recovered donor. Two of the three patients who had been breathing with the help of a mechanical ventilator were able to step down to oxygen delivered into the nose.

None of the 10 patients died, and only one unexpected side effect — a red bruise on one patient’s face — was detected.

The study was not designed to have a comparison group of patients that got no convalescent plasma. But the authors did create a control group from a random selection of 10 COVID-19 patients treated in the same hospitals and matched to the 10 study participants in age and gender and the illness severity.

The two groups looked roughly the same on day one of their admissions to the hospital. But over the next several weeks, their illnesses progressed in sharply different ways. In the comparison group, three died, six saw their conditions stabilise, and one got better during the study period.

Of those who received convalescent plasma, three were discharged from the hospital, and the remaining seven were rated “much improved” and ready for discharge.

“This pilot study on [convalescent plasma] therapy shows a potential therapeutic effect and low risk in the treatment of severe COVID-19 patients,” the authors of the new research wrote. “One dose of [convalescent plasma] with a high concentration of neutralising antibodies can rapidly reduce the viral load and tends to improve clinical outcomes,” they added.

The authors, led by Kai Duan of China’s National Biotec Group Co. Ltd., said that only larger and more detailed studies will clarify the dose at which convalescent plasma produces the most healing effects, and when it should ideally be administered.

In recent days, the New York Blood Centre has issued an urgent appeal for recovered COVID-19 patients to donate blood plasma for the creation of antibody-rich infusions. The first state blood bank to become a central repository for convalescent plasma, NYBC will collect, process the plasma for infusion, and maintain a bank for hospitals to treat patients with serious or immediately life-threatening COVID-19 infections.

Operating under guidelines released last week by the American Association of Blood Banks, an international nonprofit agency focused on transfusion medicine and cellular therapies, dozens of community blood centres nationwide have also begun gathering blood to create such treatments.

The Mayo Clinic in Rochester, Minnsota, also has launched a small trial of convalescent plasma as a means of reducing COVID-19 complications.

Mitsubishi Montero Sport 4WD: Big on presence and ability

By - Apr 06,2020 - Last updated at Apr 06,2020

Winner of the 2020 Middle East Car of the Year awards’ Midsize SUV category in a segment well fielded with accomplished models, the Mitsubishi Montero Sport is a practical, accessible and attainable vehicle with plenty of refinement, generous equipment levels, genuine off-road ability and an imposingly towering road presence. Only just smaller than Mitsubishi’s highly popular and long-established Pajero flagship SUV model, the Montero Sport offers similarly levels of ability, space and comfort, in addition to more advanced driver assistance systems and an 8- rather than 5-speed gearbox.

Whether the Montero Sport will compete with or eventually replace the aging but still very impressive Pajero one can speculate. However, given that the Montero Sport is known in certain markets as the ‘Pajero Sport’ and that our more familiar Pajero is likewise sold in some markets under the ‘Montero’ nameplate, one assumes that the differentiation in the pair’s naming strategy, indicates that the two are intended to complement each other in Middle East markets. Set to run side-by-side for now, the two models’ design is similarly distinct.

 

Overtly assertive

 

Tall and imposing with squinting headlights aside a slim three-slat chrome and browed by clamshell bonnet, the Montero Sport’s height is emphasised by its huge lower intake, framed with C-shaped chrome trim and flanked by side lights. The Montero Sport’s high-set bonnet, tall cabin and roofline and upward waistline kink at the rearmost side window all underline its height. Similarly, a thick side crease extending from the headlight edges, over bulging squared-off wheel-arches and then extending into and bisecting slim vertical rear lights also seem to emphasise height.  

Rugged and jutting in its design, surfacing and demeanour, the Montero Sport, with its shorter length yet longer wheelbase and more pronounced bonnet and overhang, doesn’t quite have the Pajero’s classical rear-biased stance. But it does achieve a similar sense of visual rear ‘weight’ to help lend a certain sense of urgency to its design. Meanwhile under its muscularly contoured and tall bonnet, the range-topping Montero Sport version is powered by a naturally-aspirated in-line 3-litre V6 engine driving all four wheels and mated with a smooth-shifting 8-speed automatic gearbox.

 

Confident delivery

 

Developing 215BHP at 6,000rpm and 210lb/ft torque at 4,000rpm, the Montero Sport benefit from its broad range of gear ratios to make the most of its output to maximise performance and minimise fuel consumption. Able to achieve a 180km/h top speed, is meanwhile estimated to cover the 0-100km/h acceleration benchmark in around 10-seconds or less, even with its near two-tonne weight in the top spec 3-litre 4WD variant, as tested. Smooth and progressive in delivery and build-up, the Montero Sport moves at a good pace in town and the open road.

Refined and insulated inside, the Montero Sport isn’t and doesn’t feel particularly fast, but is quick enough and never feels short, whether setting off from standstill or overtaking in mid-range or reaching for its rev limit. Driving in rear-wheel-drive in normal conditions to reduce consumption, the Montero Sport’s four-wheel-drive system can be engaged in 4H mode on tarmac or moderate off-road conditions for added traction and grip, where it drives with a 60 per cent rear bias to lend it more agility and feeling of balance like a rear-wheel-drive vehicle.

 

Capability and comfort

 

A capable off-roader that proved effortless through desert and dunes in regular four-wheel-drive mode during test drive, the Montero Sport is, the Montero Sport features a locking centre differential when additional traction is needed, and low gear ratios for high power driving at a crawling pace when necessary for yet more demanding conditions. A drive mode selector meanwhile optimises wheel slip, transmission, braking and engine torque for different surfaces and conditions. The Montero sport also features generous 218mm ground clearance and 30° approach, 23.1° ramp and 24.2° departure angles.

A comfortable and refined drive that well insulates occupants from bumps, lumps and road imperfections with its absorbent tyres and forgiving suspension, the Montero Sport is a smooth and relaxed ride with good highway stability too. Riding high and comfortably, it leans slightly through corners but nevertheless feels balanced, grippy and committed throughout. Tidy into corners with its balanced weight distribution, the Montero Sport is reassuring if not particularly sporty. Steering meanwhile is accurate but light and set-up for comfort rather than edgy feel and feedback.

 

Spacious and convenient

 

A spacious and big 7-seat SUV with plenty of room for passengers and luggage, the Montero Sport, however, feels like a bigger and wider vehicle from the driver’s seat, owing to its high-set bonnet. Nevertheless, despite the high bonnet, the Montero Sport is a more manoeuvrable vehicle than many in its class, with a comparatively narrow body and tight 11.2-metre turning circle. Parking sensors and an around view camera meanwhile add more confidence in tight confines.

Pleasant, user-friendly and well appointed with good quality materials, the Montero Sport is also well-equipped with convenience, infotainment and safety features including a two-sensor automatic tailgate, seven airbags and driver assistance systems like rear cross-traffic alert, adaptive cruise control, lane change assistance and a forward collision mitigation system.

How to sleep when you can’t stop thinking about coronavirus: Experts offer tips

By - Apr 06,2020 - Last updated at Apr 06,2020

There’s nothing like a dark, quiet bedroom to send a stressed-out mind down a rabbit hole of worry, and the coronavirus is giving us all a new set of possible catastrophes to feast upon.

As your head hits the pillow, or maybe when you stir at 2am, you start to wonder: Does that little sore throat mean you’re doomed? What if that guy who stood too close at the grocery store had the virus? Can your father or grandfather — or you — survive this?

It goes on and on, and pretty soon you’re worried that you’ll never get to sleep, and you’ll feel horrible the next day. Plus, you need sleep for a strong immune system, so staying awake could make you sick. This kind of thinking is a recipe for insomnia.

“Six months from now, we’re going to have a much larger population of adults with insomnia, and certainly children,” said Amy Sawyer, who has a doctorate in nursing at Penn Nursing and studies health behaviours related to sleep.

Other experts were not as sure that insomnia would soon go viral but did say they’re hearing that patients, as well as friends, coworkers, and family members, are having more trouble than usual getting to sleep or staying asleep in these anxious times.

“Sleep is one of the first things that goes,” said Phil Gehrman, a psychologist at the Penn Sleep Centre. “I describe sleep as our barometer.”

We asked Sawyer, Gehrman, Michael Grandner, who directs the Sleep and Health Research Program at the University of Arizona’s College of Medicine, and Bilal Saulat, a neurologist who is medical director of sleep medicine at Tower Health Medical Group, how to fight back against the mostly irrational thoughts that pop into your head as soon at it hits the pillow. The solutions, they said, start long before bedtime.

Our schedules help set our circadian rhythms, the internal clock that helps us know when it’s time to wake and sleep.

Now that so many of us are either working at home or home without work, our schedules have gone haywire. Grandner says there’s one group that’s loving this: the natural night owls who hated getting up early to commute and take kids to school.

“They’ve removed a major stress from their morning,” he said. Many others, though, are unmoored to their normal routines. “You have people who are just playing video games all day,” Grandner said. “Their body is having a hard time knowing when to be awake and when to be sleeping.”

So, get on a schedule and try to stay on it. The wake-up time is especially important. Try not to deviate by more than an hour. Eat meals at regular times, but don’t eat big meals close to bedtime. Maintain regular morning and evening routines — showers, tooth brushing, face washing, etc. — that cue your body to wake up or sleep.

Try to get outside for at least 15 minutes, preferably in the morning. This is also important for circadian rhythms. If possible, open a curtain so you wake to sunlight.

Exercise will help relieve stress. Just don’t do it near bedtime. It raises core body temperature, while falling body temperature triggers sleep, Gehrman said. He recommends no exercise within an hour or two of bedtime.

“The bedroom is for sleep and sex, and if you’re doing anything else in it, you shouldn’t,” Sawyer said.

That means no television and no other screens. “It is never OK to use screens or TVs in your bedroom,” Saulat said.

Sleep experts might occasionally make an exception for paperbound books, but you don’t want a real page-turner at bedtime.

Also, Sawyer said, people tend to sleep better in a cooler bedroom. Set the thermostat at 68 or below.

Grandner talks about “landing the plane,” not hoping it can just drop out of the sky.

Do things that relax you in the hours leading up to bed.

Read, stretch, knit, meditate.

It pains us to say this, but the experts agreed that loading up on news about the coronavirus before bed is not a good thing. Yes, the news is changing all the time, but Grandner said there’s nothing you can do about it, and it will still be there for your consumption in the morning.

Without prompting, Saulat said he thinks there’s a lot to be said for reading a newspaper once in the morning and then going about your life.

Grandner wouldn’t go that far, but counsels unplugging well before bedtime. “The time for reading stressful news is not within an hour of going to bed,” he said.

Either turn off the blue light on your screens at night or shut devices off completely. Saulat said that turning screens off two to four hours before bedtime can make a “huge” difference in sleep.

Sawyer said many of her students are binge-watching Netflix, which is not conducive to sleep.

“The blue light that’s emitted from electronic devices is wake-setting to your brain,” she said. “It basically cues your brain that it’s wake time.” She recommends turning devices off 15 to 30 minutes before sleep.

Saulat said not to use prescription pills. Most people can fix their sleep problems by learning to change their behaviour.

Don’t drink caffeinated beverages after noon. Alcohol may help you go to sleep but it disrupts sleep afterward.

Nicotine makes it harder to go to sleep and stay asleep.

If you know your mind tends to spin at bedtime, try setting a specific time to worry earlier in the day for, say, 15 minutes. Acknowledge what you’re feeling and what you’re doing to protect yourself and your family. Take solace in knowing you’re doing everything you can, Sawyer said, and accept that you can’t control everything. Some people find it helpful to write this down.

Saulat usually adds a third category: Is it going to kill me? He concedes that’s not an ideal question now.

The black of night is not the time, the experts said, to try to talk sense to your fears. In the dark, think of yourself as an emotional 12-year-old, Grandner said. Telling yourself that the odds are minuscule that the cat’s sneeze gave you the coronavirus probably won’t stop that thought.

At night, he said, “You tend to blow things out of proportion. … You tend to be very bad at putting things in perspective. … Sometimes, we have to give ourselves permission to be irrational creatures.”

Humans seem to be primed for scary thoughts at night, Gehrman said. “No one ever tells me they lie awake in bed thinking happy thoughts,” he said. He agrees with Grandner that “it’s really difficult in the middle of the night to make yourself see reason.”

What about strange apocalyptic dreams?

Gehrman doesn’t put much stock in dream analysis but said dreams can reflect unresolved problems. “Our daytime emotions follow us into our sleep,” he said.

If you’ve spent more than 10 minutes ruminating about the end of the world, it’s time to take your brain elsewhere. You don’t want your body to associate the bed with wakefulness.

“Don’t turn your bed into a thinking couch,” Saulat said.

Get up and do something that relaxes you and takes your mind off your specific worry. The sleep experts are fans of meditation — if you’re new to this, you can find online guided imagery programs — and progressive relaxation techniques. For relaxation, start at your toes or head and slowly tighten and then relax muscles. Gradually do this until you reach the other end of the body.

Mindfulness meditation and breathing techniques can help you learn to focus on the now instead of worrying about the future.

Sawyer recommends a technique that she uses every night. Bring your focus to your breath while breathing normally. Count at the end of each exhalation until you reach 10 and then count from 10 to one. “At the end, I feel very relaxed,” she said. If you haven’t done this before, you may have to start with a smaller number of breaths.

When you feel sleepy, go back to bed.

The new coronavirus might spread when people talk or breath, but scientists say masks can help

By - Apr 05,2020 - Last updated at Apr 05,2020

MILLBRAE, California — It’s possible that the new coronavirus can spread from person to person simply by talking, or even breathing, according to new guidance from the National Academies of Sciences, Engineering and Medicine.

The limited studies examined by a National Academies committee on emerging infectious diseases suggest that people who are infected with the novel virus may exhale infectious “bioaerosols” — although if they do, it’s not clear whether the amount would be enough to make another person sick.

“The results of available studies are consistent with aerosolisation of virus from normal breathing,” the head of the committee, Dr Harvey Fineberg, wrote in a letter to to Kelvin K. Droegemeier, the director of the White House Office of Science and Technology Policy.

The letter was drafted to answer a question posed by Droegemeier: Can the virus responsible for COVID-19 spread through conversation?

To formulate an answer, the committee considered a study posted last week by a team from the University of Nebraska Medical Centre. Researchers there collected air samples from 11 isolation rooms where COVID-19 patients were treated. They also looked for evidence of the virus on surfaces.

The researchers found viral RNA in air that was captured more than 1.8 metres from patients. They also found it in air from the hallway outside patient rooms, according to the study.

Notably, the researchers said none of the patients were seen coughing while air samples were being taken.

“You don’t have to be hacking, coughing… in order to be producing a particle that at least has viral RNA in it,” study leader Joshua Santarpia, a professor of pathology and microbiology at the University of Nebraska Medical Centre, said in an interview.

The study was published on a website for time-sensitive medical research and has not been through the traditional peer-review process.

In summarising the findings, Fineberg wrote: “While this research indicates that viral particles can be spread via bioaerosols, the authors stated that finding infectious virus has proved elusive.”

He added that the Nebraska team is conducting additional experiments to see whether the amount of virus in their air samples is dangerous.

Dr George Rutherford, epidemiologist and infectious diseases expert at UC San Francisco, said he wasn’t surprised that the virus could spread by breathing and talking.

“Think of what your breath looks like when you go to Mammoth Mountain and you can see it — those are respiratory droplets,” he said. “Of course, you can get it while you’re talking to somebody. If you’re within 1.8 metres, you’re at some risk for that.”

Infected droplets can also spread in the air by singing, Rutherford said, citing the case of a choir practice in Washington state last month. A total of 45 people who attended that practice were diagnosed with COVID-19; two have died and at least three have been hospitalised.

The National Academies letter also highlighted a study, which was published Friday as a brief communication in the journal Nature Medicine, that suggests surgical masks can help keep an infected person from transmitting the virus to others.

The study authors collected air samples of breaths exhaled by patients in a Hong Kong clinic between 2013 and 2016. Some patients wore masks, and some didn’t.

For people who were infected with a common type of coronavirus that causes colds — not the one associated with the current pandemic — the virus was sometimes found in exhalations when no facemask was worn. But when masks were in place, no virus particles could be detected.

“This has important implications for control of COVID–19, suggesting that surgical face masks could be used by ill people to reduce onward transmission,” wrote the study authors, who were from the University of Hong Kong, the Harvard School of Public Health and the University of Maryland School of Public Health.

On Friday, the US Centres for Disease Control and Prevention changed its guidance and advised Americans to wear face coverings when they leave their homes.

Social dis-dance: clubbing goes online as virus shuts nightspots

By - Apr 04,2020 - Last updated at Apr 04,2020

"Zouk" nightclub throwing a "cloud-clubbing" party after Singapore ordered the closure of many entertainment venues (AFP photo by Catherine Lai)

SINGAPORE — Strobe lights flash across a near-empty dance floor, as a DJ live-streams thumping electronic music from a Singapore nightclub to revellers confined to their homes due to the coronavirus pandemic.

The outbreak sweeping the globe has shuttered once lively nightspots from London to New York, but innovative DJs have started putting their performances online so clubbers don't miss out.

The trend is another example of how the virus, which has left some 3.6 billion people stuck at home under lockdowns, is upending daily life in ways unthinkable until recently as governments impose social-distancing curbs to stem its spread.

After Singapore ordered the closure of many entertainment venues last week following a steady rise in infections, popular nightclub "Zouk" threw a "cloud-clubbing" party, streaming live performances by six DJs via an app.

It took place on a Friday night when the club is often packed with hundreds of partygoers — but only a handful of people were allowed to attend, most of them staff members.

DJ Nash D conceded he found it weird at first.

"When you play for a dance floor with a room full of people, you can feel the energy come back, and I like to DJ off that energy," the DJ, real name Dhanish Nair, told AFP.

But he quickly got used to it, and said live comments from clubbers scrolling past on his laptop were helpful: "Whatever song requests that they had actually guided me in a certain direction."

As well as the comments which came in via live-streaming app Bigo Live, clubbers sent virtual gifts to the DJs such as bells and snowflakes that can later be exchanged for cash.

The nightclub partnered with gaming equipment company Razer and the live-streaming app, attracting 200,000 total views for the three-hour event. At its peak, 5,600 people were watching via the app.

 

'Dancing together, apart'

 

In China, where the virus first emerged last year, DJs and nightspots started live-streaming performances at the beginning of February when the country's outbreak was at its pinnacle.

Shanghai and Beijing venues pioneered live-streamed clubbing on Douyin, China's version of TikTok, which also allows fans to buy gifts which can be swapped for cash.

Beijing club One Third attracted over a million viewers and generated nearly two million yuan ($280,000) in rewards from its fans in a five-hour live-stream, according to news website iFeng.

Closed nightclubs and DJs stuck at home are also hosting virtual dance parties in New York, the epicentre of America's worsening outbreak.

Live performance outfit "The Dance Cartel" has started hosting "Social Disdance" parties for "dance nights together, apart" three times a week.

Participants dance with one another over the Zoom video chat app, with some donning costumes and others setting up colourful disco lights.

The parties are free but people are encouraged to make donations to the DJs and hosts.

With the death toll from the virus now above 42,000 globally and no sign of the pandemic slowing down, online clubbing only looks set to get more popular.

Singapore's decision to close nightclubs came as authorities slowly tighten restrictions following a jump in cases, with the city-state so far having reported over 900 infections and three deaths.

Despite the challenges, some performers are slowly warming to the idea of online clubbing.

"Online, I feel that everybody is more in their natural state," said Singapore DJ LeNERD, real name Patrick Lewis, who played at Friday's event.

"They are more themselves and they are more honest."

Smartphone versus virus, is privacy always going to be the loser?

PARIS — In Europe, officials, doctors and engineers are looking at how smartphones could be enlisted in the war against the spread of the new coronavirus.

One obvious attraction for health officials is the possibility of using smartphones to find out with whom someone diagnosed with COVID-19 has been in contact.

But can this be done without intrusive surveillance and access to our devices that store a wealth of private information?

 

Anonymised and aggregated

 

Firms can "anonymise" location data received from your smartphone by stripping out personal identifiers. It can then be presented in an "aggregate" form where individual and identifiable data points are not accessible.

Your location data is already likely being used that way by mobile operators to feed traffic information to map apps.

And it is such information that the European Commission has requested from mobile operators, which can determine the location of users by measuring the phone signal strength from more than one network tower.

In fact, mobile operators have already been providing such data to health researchers in both France and Germany.

Google, which collects large amounts of data from users of its myriad services, plans to publish information about the movement of people to allow governments to gauge the effectiveness of social distancing measures.

In particular, it will display percentage point increases and decreases in visits to such locations as parks, shops, and workplaces.

 

Bluetooth sleuth

 

Anonymised and aggregated only get you so far. To get practical data like the people with whom an infected person has had contact, you need to get invasive. Or do you?

Singapore pioneered a method using Bluetooth. This is the technology that allows people to connect wireless headphones or earbuds to their smartphones.

If you've ever connected a pair to your phone in a public place you'll probably have noticed the devices of others nearby.

It is this feature of Bluetooth that the Singaporean app TraceTogether exploits.

Someone who has downloaded the app and kept their Bluetooth enabled will begin to register codes from all people who have the app on their phone and come within range.

Germany is looking at rolling out a similar system.

 

Privacy concerns

 

The Singaporean app is designed to reduce privacy concerns.

For one, the app is voluntary.

Another is that it doesn't track your location, rather it just collects codes from the phones of people with whom you come into relatively close contact.

That information is only uploaded to the operator of the app when a person declares himself or herself as having come down with COVID-19.

The TraceTogether app then matches up the codes (non-identifiable except to the operator of the system) with the telephone number of owners, and then messages them they had been in contact with someone who has been diagnosed with COVID-19.

 

Spies in charge

 

The other means to get practical information is to utilise the location data of phone users.

This is the method chosen by Israel, which put internal security agency Shin Bet in charge of obtaining the data from mobile phone operators.

It also gets access to data on the movement of people for a two-week period to help track down people exposed to the coronavirus.

Shit Bet does not get access to a person's phone, however.

 

'Proportionate and temporary'

 

Putting the fox in charge of guarding the henhouse is unlikely to sit well with rights and privacy groups, although they don't exclude the use of technology to help combat the crisis.

"However, States' efforts to contain the virus must not be used as a cover to usher in a new era of greatly expanded systems of invasive digital surveillance," said a statement issued Thursday by 100 rights groups including Amnesty International, Privacy International and Human Rights Watch.

They warn that "an increase in state digital surveillance powers, such as obtaining access to mobile phone location data, threatens privacy, freedom of expression and freedom of association, in ways that could violate rights and degrade trust in public authorities — undermining the effectiveness of any public health response."

They said any additional digital surveillance powers should be necessary, proportionate and temporary.

"We cannot allow the COVID-19 pandemic to serve as an excuse to gut individual's right to privacy," the groups said.

A surge of apps programming

It has been here since the very beginning of the modern computer era, circa the 1950s, and it is proving now that it is more important than ever, with the sudden surge in the demand for software applications of all kinds, because of the confinement situation that wants us to stay at home and to work remotely. It is computer programming.

A certain number of elements come together to make the Internet work. Electricity, various computer hardware, cabling, data storage, Internet Service Providers, routers, protocols, etc. Whereas each is indispensable, the system would not work at all without good programming. It is worth remembering that, on the dark side of technology, computer viruses too are nothing but programmes.

At the basic level of the web, a good browser is the programme, the software tool that lets you open a window to look at the world. Chrome, Safari, Firefox and Edge are the main browsers, with Google’s Chrome claiming the market lion’s share with about 56 per cent of the world web traffic, according to techadvisor.co.uk report last month. Google has just announced that given the crisis situation it is postponing just a little the release of Chrome’s upcoming version update.

Whatever you may be doing, with a laptop computer or a smartphone, online or offline, for personal use or for business, as a critical task or just for fun, you cannot do it without a programme. We tend to forget this essential point of technology.

There are “big” programmes and then there are what we now commonly call applications of “apps” – they are programmes too, of course, but are usually smaller and they mainly target mobile devices and users. The first category includes web browsers like the ones mentioned above, operating systems like Windows, Android, iOS, MacOS, Microsoft Office Suite, Adobe Photoshop, Oracle database, and so forth.

The second category would include the myriad of mobile applications that make our smartphones what they are, and that we find, typically on Apple Store or Google Play. The last name is a bit deceptive for it covers all kinds of applications and is not about playing or games, though it does include this type of programmes too.

The surge now understandably is on the apps side, given the trend to go mobile in most everything.

Banks are fine-tuning their apps and adding to them, supermarkets and food delivery outlets are resorting to apps to take orders and to process them in this time of massive confinement. On-call taxis services – Careem for instance – are adding functionality to their already existing apps to ensure more flexibility in their business. Governments in all countries are doing the same and are relying on apps to improve the communication with their population.

Never before has the demand for apps, and consequently for good programmers, has been so high. The most popular programming languages for apps are Java, C, C++ or C#, php, and … Corona (yes, it is correct)! Corona is a software development kit initially developed circa 2010 by Corona Labs Inc. It works on Android and iOS as well. Its newest release dates back to end 2018. It is less frequently used that Java and the other languages, but is still used in apps for Apple and Android TV, for instance.

The young generation of programmers for apps tends to go for Java and C++, essentially. Very different from the world of large applications that are mainly designed and produced by the big players like Microsoft, Adobe or Oracle, apps are at the reach of even freelancers. It is a fascinating world and it has opened the door to creativity, free enterprise and billions in revenue for the creators. The current confinement situation is working as a significant booster for apps developers.

Measles threat grows amid COVID-19 crisis: vaccine group

GENEVA — With all eyes on the rapid global spread of the novel coronavirus, health experts fear a drop in routine vaccinations could fuel other, potentially deadlier outbreaks of diseases like measles.

With nearly half of the world's population told to stay at home, many parents are having to postpone taking their children in for routine immunisations, while big vaccine drives have been halted, leaving many vulnerable to a range of infectious diseases.

"Measles is probably number one in my worry list at the current time," Seth Berkley, who heads the Gavi Vaccine Alliance, told AFP in an interview.

He warned of the impact that an outbreak of measles or other diseases could have on health services already reeling from the COVID-19 pandemic, which has killed some 50,000 people and infected over 900,000 worldwide in a matter of months.

"Routine immunisation is absolutely critical always, but is particularly critical at a time like this because if other outbreaks occur, they will overwhelm the health system," Berkley said.

He pointed out that during the Ebola outbreak in the Democratic Republic of Congo's North Kivu region, which has killed nearly 2,300 people since mid-2018, measles has proved more deadly.

"Everybody was focused on Ebola, but 2.5 times the number of people died in the country from measles than died from Ebola," he said.

Gavi provides vaccines against a wide range of diseases for the 60 per cent of the world's children who live in developing countries.

While it may not be too big a deal to delay vaccines for some of those diseases for a few months, timely immunisation against the more contagious ones like measles is essential.

 

'Massive outbreaks'

 

Already, the world is facing a resurgence of the once all-but-eradicated disease, which is a highly contagious, sometimes fatal viral infection.

Poorer countries are hit hardest. The vast majority of the more than 140,000 global measles deaths recorded by the World Health Organisation in 2018 were in sub-Saharan Africa.

But a growing anti-vaccine movement has also helped spark measles outbreaks in many richer countries in recent years.

The anti-vax phenomenon has adherents across Western countries but especially in the United States, where it has been fuelled by the spread on social media of medically baseless claims, debunked 20 years ago, that the jab could cause autism.

Berkley pointed out that Europe has seen recent outbreaks in 47 out of 53 countries, warning that while the outbreaks had been small, if vaccination coverage falls, "these could be massive outbreaks".

He acknowledged that the physical distancing measures in place in many countries to halt a spread of the new coronavirus could also prevent broad spread of other infectious diseases too.

"If there is less contact there is less likely to be an explosive spread," he said, while stressing that "measles is even more infectious than COVID".

Meanwhile, Berkley said the pandemic might undermine the anti-vaccine movement.

He pointed out that one reason behind the hesitancy to immunise in wealthy countries was that "vaccines have been so successful that we don't see the diseases [they protect against] anymore."

"So it is easy to say: oh, these diseases aren't so severe, and we don't want to put non-organic things in our bodies, or we are worried about side-effects or whatever," he noted.

"I have a feeling that if there was a COVID vaccine right now, there might be more appetite to use it than has been the case for other vaccines."
