Jun 9: The World Health Organization says it still believes the spread of the coronavirus from people without symptoms is “rare,” despite warnings from numerous experts worldwide that such transmission is more frequent and likely explains why the pandemic has been so hard to contain.

Maria Van Kerkhove, WHO''s technical lead on COVID-19 said at a press briefing on Monday that many countries are reporting cases of spread from people who are asymptomatic, or those with no clinical symptoms.

But when questioned in more detail about these cases, Van Kerkhove said many of them turn out to have mild disease, or unusual symptoms.

Although health officials in countries including Britain, the U.S. and elsewhere have warned that COVID-19 is spreading from people without symptoms, WHO has maintained that this type of spread is not a driver of the pandemic and is probably accounts for about 6 per cent of spread, at most.

Numerous studies have suggested that the virus is spreading from people without symptoms, but many of those are either anecdotal reports or based on modeling.

Van Kerkhove said that based on data from countries, when people with no symptoms of COVID-19 are tracked over a long period to see if they spread the disease, there are very few cases of spread.

“We are constantly looking at this data and we''re trying to get more information from countries to truly answer this question,” she said. “It still appears to be rare that asymptomatic individuals actually transmit onward.”

United Nations, Jun 19: Half of the world's children -- one billion every year -- are affected by physical, sexual or psychological violence, suffering injuries and death because countries have failed to follow established strategies to protect them, the first report of its kind from the UN has said, with experts noting that the coronavirus-related lockdowns have left far too many youngsters stuck with their abusers.

While nearly all countries (88 per cent) have laws in place to protect minors, less than half (47 per cent) say they strongly enforce them, said the Global Status Report on Preventing Violence Against Children 2020 launched on Thursday.

Because countries have failed to follow established strategies to protect children, about one billion are affected each year by physical, sexual or psychological violence, it said.

"There is never any excuse for violence against children," WHO Director-General Tedros Adhanom Ghebreyesus said.

"We have evidence-based tools to prevent it, which we urge all countries to implement. Protecting the health and well-being of children is central to protecting our collective health and well-being, now and for the future," he said.

The report -- launched by the World Health Organisation, the UNICEF, the UNESCO, the Special Representative of the UN Secretary-General on Violence against Children and the End Violence Partnership -- charted progress in 155 countries against the "INSPIRE" framework, a set of seven strategies for preventing and responding to violence against children.

The report signaled a clear need in all countries to scale up efforts to implement them. It included the first ever global homicide estimates specifically for children under 18 years of age -- previous estimates were based on data that included 18 to 19-year olds.

According to the findings, in 2017, around 40,000 children were victims of homicide.

"Violence against children has always been pervasive, and now things could be getting much worse," UNICEF Executive Director Henrietta Fore said.

"Lockdowns, school closures and movement restrictions have left far too many children stuck with their abusers, without the safe space that school would normally offer. It is urgent to scale up efforts to protect children during these times and beyond, including by designating social service workers as essential and strengthening child helplines," she said.

UNESCO Director-General Audrey Azoulay said during the COVID-19 pandemic, and the related school closures, "we have seen a rise in violence and hate online – and this includes bullying".

"Now, as schools begin to re-open, children are expressing their fears about going back to school. It is our collective responsibility to ensure that schools are safe environments for all children. We need to think and act collectively to stop violence at school and in our societies at large," Azoulay said.

Stay-at-home measures including school closures have limited the usual sources of support for families and individuals such as friends, extended family or professionals.

This further erodes victims’ ability to successfully cope with crises and the new routines of daily life. Spikes in calls to helplines for child abuse and intimate partner violence have been observed, the report said.

While online communities have become central to maintain many children's learning, support and play, an increase in harmful online behaviors including cyberbullying, risky online behavior and sexual exploitation have been identified.

“Whilst this report was being finalised, confinement measures and the disrupted provision of already limited child protection services exacerbated the vulnerability of children to various forms of violence," said Najat Maalla M’jid, Special Representative of the UN Secretary-General on Violence against Children.

Of the INSPIRE strategies, only access to schools through enrolment showed the most progress with 54 per cent of the countries reporting that a sufficient number of children in need were being reached in this way.

Between 32 per cent and 37 per cent of the countries considered that victims of violence could access support services, while 26 per cent of the countries provided programmes on parent and caregiver support; 21 per cent of the countries had programmes to change harmful norms; and 15 per cent of the countries had modifications to provide safe physical environments for children, the report said.

Although a majority of countries (83 per cent) have national data on violence against children, only 21 per cent used these to set baselines and national targets to prevent and respond to violence against children, it added.

The report said about 80 per cent of countries have national plans of action and policies but only one-fifth have plans that are fully funded or have measurable targets. A lack of funding combined with inadequate professional capacity are likely contributing factors and a reason why implementation has been slow.

"Ending violence against children is the right thing to do, a smart investment to make - and it's possible. We can and must create a world where every child can thrive," Howard Taylor of the End Violence Partnership said.

May 28: Boeing is cutting more than 12,000 jobs through layoffs and buyouts as the coronavirus pandemic seizes the travel industry, and more cuts are coming.

One of the nation's biggest manufacturers will lay off 6,770 U.S. employees this week, and another 5,520 workers are taking buyout offers to leave voluntarily in the coming wee

Air travel within the U.S. tumbled 96% by mid-April, to fewer than 100,000 people on some days. It has recovered slightly. The Transportation Security Administration said it screened 264,843 people at airports on Tuesday, a drop of 89% compared with the same Tuesday a year ago.

Boeing had said it would cut 10% of a work force that numbered about 160,000. A Boeing spokesperson said Wednesday's actions represent the largest number of job cuts, but several thousand additional jobs will be eliminated in the next few months.

The layoffs are expected to be concentrated in the Seattle area, home to Boeing's commercial-airplanes business. The defense and space division is stable and will help blunt the impact of the decline in air travel and demand for passenger jets, the company said.

Boeing said additional job cuts will be made in international locations, but it did not specify numbers.

"The COVID-19 pandemic's devastating impact on the airline industry means a deep cut in the number of commercial jets and services our customers will need over the next few years, which in turn means fewer jobs on our lines and in our offices," CEO David Calhoun said Wednesday in a memo to employees.

Calhoun said the company faces the challenges of keeping employees safe and working with suppliers and airlines "to assure the traveling public that it can fly safe from infection."

Calhoun warned that Boeing will have to adjust business plans constantly because the pandemic makes it hard to predict the impact on the company's business.

Boeing's crisis began with two crashes of its 737 Max, which led regulators around the world to ground the jetliner last year. The company's problems have deepened with the coronavirus, which has cut global air traffic by up to 90% and caused airlines to postpone or cancel orders and deliveries for new planes.

Jun 4: A malaria drug President Donald Trump took to try to prevent COVID-19 proved ineffective for that in the first large, high-quality study to test it in people in close contact with someone with the disease.

Results published Wednesday by the New England Journal of Medicine show that hydroxychloroquine was no better than placebo pills at preventing illness from the coronavirus.

The drug did not seem to cause serious harm, though -- about 40% on it had side effects, mostly mild stomach problems.

 “We were disappointed. We would have liked for this to work,” said the study leader, Dr. David Boulware, an infectious disease specialist at the University of Minnesota.

“But our objective was to answer the question and to conduct a high-quality study,” because the evidence on the drug so far has been inconclusive, he said.

Hydroxychloroquine and a similar drug, chloroquine, have been the subject of much debate since Trump started promoting them in March.

Hydroxychloroquine has long been used for malaria, lupus, and rheumatoid arthritis, but no large studies have shown it or chloroquine to be safe or effective for much sicker patients with coronavirus, and some studies have suggested the drugs may do harm.

Trump took a two-week course of hydroxychloroquine, along with zinc and Vitamin D, after two staffers tested positive for COVID-19, and had no ill effects, according to results of his latest physical released by his doctor Wednesday.

Federal regulators have warned against hydroxychloroquine's use except in hospitals and formal studies because of the risk of side effects, especially heart rhythm problems.

Boulware's study involved 821 people in the United States and Canada living with someone diagnosed with COVID-19 or at high risk of getting it because of their job -- doctors, nurses, ambulance workers who had significant exposure to a sick patient while not wearing full protective gear.

They were randomly assigned to get either the nutrient folate as a placebo or hydroxychloroquine for five days, starting within four days of their exposure. Neither they nor others involved in the research knew who was getting which pills.

After 14 days in the study, 12 per cent on the drug developed COVID-19 symptoms versus 14 per cent in the placebo group, but the difference is so small it could have occurred by chance, Boulware said.

“There's basically no effect. It does not prevent infection,” he said of the drug. Even if it were to give some slim advantage, “we'd want a much larger effect” to justify its use and risk of side effects for preventing illness, he said.

Results were no different among a subgroup of participants who were taking zinc or vitamin C, which some people believe might help make hydroxychloroquine more effective or fight the coronavirus.

There are some big caveats: The study enrolled people through the Internet and social media, relying on them to report their own symptoms rather than having them tracked in a formal way by doctors.

Participants were not all tested for the coronavirus but were diagnosed as COVID-19 cases based on symptoms in many cases. And not all took their medicines as directed.

The results “are more provocative than definitive,” and the drug may yet have prevention benefits if tried sooner or in a different way, Dr. Myron Cohen of the University of North Carolina at Chapel Hill wrote in a commentary in the journal.

Others were glad to see a study that had a comparison group and good scientific methods after so many weaker reports on hydroxychloroquine.

“This fits with everything else we've seen so far which suggests that it's not beneficial," said Dr. Peter Bach, director of a health policy center at Memorial Sloan Kettering Cancer Center in New York.

This study was in younger relatively healthy people, but the results “would make me very discouraged about trying to use this in older people” who are most vulnerable to serious illness from the coronavirus, Bach said.

“If it does work, it doesn't work very well.” Dr. Dan Culver, a lung specialist at the Cleveland Clinic, said there's still a chance that giving the drug sooner than four days after someone's exposure to the virus may help prevent illness.

But the study “takes 'home run' off the table” as far as hopes for the drug, he said.

The study was mostly funded by David Baszucki, founder of Roblox, a California-based game software company, and other private donors and the Minnesota university.

Boulware also is leading a study testing hydroxychloroquine for treating COVID-19. The study is finished and results are being analyzed now.

On Tuesday, the journal Lancet posted an “expression of concern” about a study it published earlier this month of nearly 15,000 COVID-19 patients on the malaria drugs that tied their use to a higher risk of dying in the hospital or developing a heartbeat problem.

Scientists have raised serious questions about the database used for that study, and its authors have launched an independent audit.

That work had a big impact: the World Health Organization suspended use of hydroxychloroquine in a study it is leading, and French officials stopped the drug's use in hospitals. On Wednesday, the WHO said experts who reviewed safety information decided that its study could resume.
