Hijab-wearing White House staffer quits Trump administration in 8 days

May 19: A Chinese laboratory has been developing a drug it believes has the power to bring the coronavirus pandemic to a halt.

The outbreak first emerged in China late last year before spreading across the world, prompting an international race to find treatments and vaccines.

A drug being tested by scientists at China's prestigious Peking University could not only shorten the recovery time for those infected, but even offer short-term immunity from the virus, researchers say.

Sunney Xie, director of the university's Beijing Advanced Innovation Center for Genomics, told AFP that the drug has been successful at the animal testing stage.

"When we injected neutralising antibodies into infected mice, after five days the viral load was reduced by a factor of 2,500," said Xie.

"That means this potential drug has (a) therapeutic effect."

The drug uses neutralising antibodies -- produced by the human immune system to prevent the virus infecting cells -- which Xie's team isolated from the blood of 60 recovered patients.

A study on the team's research, published Sunday in the scientific journal Cell, suggests that using the antibodies provides a potential "cure" for the disease and shortens recovery time.

Xie said his team had been working "day and night" searching for the antibody.

"Our expertise is single-cell genomics rather than immunology or virology. When we realised that the single-cell genomic approach can effectively find the neutralising antibody we were thrilled."

He added that the drug should be ready for use later this year and in time for any potential winter outbreak of the virus, which has infected 4.8 million people around the world and killed more than 315,000.

"Planning for the clinical trial is underway," said Xie, adding it will be carried out in Australia and other countries since cases have dwindled in China, offering fewer human guinea pigs for testing.

"The hope is these neutralised antibodies can become a specialised drug that would stop the pandemic," he said.

China already has five potential coronavirus vaccines at the human trial stage, a health official said last week.

But the World Health Organization has warned that developing a vaccine could take 12 to 18 months.

Scientists have also pointed to the potential benefits of plasma -- a blood fluid -- from recovered individuals who have developed antibodies to the virus enabling the body's defences to attack it.

More than 700 patients have received plasma therapy in China, a process which authorities said showed "very good therapeutic effects".

"However, it (plasma) is limited in supply," Xie said, noting that the 14 neutralising antibodies used in their drug could be put into mass production quickly.

Using antibodies in drug treatments is not a new approach, and it has been successful in treating several other viruses such as HIV, Ebola and Middle East Respiratory Syndrome (MERS).

Xie said his researchers had "an early start" since the outbreak started in China before spreading to other countries.

Ebola drug Remdesivir was considered a hopeful early treatment for COVID-19 -- clinical trials in the US showed it shortened the recovery time in some patients by a third -- but the difference in mortality rate was not significant.

The new drug could even offer short-term protection against the virus.

The study showed that if the neutralising antibody was injected before the mice were infected with the virus, the mice stayed free of infection and no virus was detected.

This may offer temporary protection for medical workers for a few weeks, which Xie said they are hoping to "extend to a few months".

More than 100 vaccines for COVID-19 are in the works globally, but as the process of vaccine development is more demanding, Xie is hoping that the new drug could be a faster and more efficient way to stop the global march of the coronavirus.

"We would be able to stop the pandemic with an effective drug, even without a vaccine," he said.

Washington, Jul 7: President Donald Trump on Tuesday formally started the withdrawal of the United States from the World Health Organization, making good on threats to deprive the UN body of its top funding source over its response to the coronavirus.

Public health advocates and Trump's political opponents voiced outrage at the departure from the Geneva-based body, which leads the global fight on maladies from polio to measles to mental health -- as well as Covid-19, at a time when cases have again been rising around the world.

After threatening to suspend the $400 million (Dh1.47 billion) in annual US contributions and then announcing a withdrawal, the Trump administration has formally sent a notice to UN Secretary-General Antonio Guterres, a State Department spokesperson said.

The withdrawal is effective in one year -- July 6, 2021 -- and Joe Biden, Trump's presumptive Democratic opponent, is virtually certain to stop it and stay in the WHO if he wins the November election.

A spokesman for Guterres and the global health body itself confirmed that the United States, a key founding WHO member, gave its notice.

In a speech earlier in the day, WHO chief Tedros Adhanom Ghebreyesus said of Covid-19, "National unity and global solidarity are more important than ever to defeat a common enemy."

In line with conditions set when the WHO was set up in 1948, the United States can leave within one year but must meet its remaining assessed financial obligations, the UN spokesman said.

'Total control'

In late May, Trump said that China exerted "total control" over the WHO and accused the UN body led by Tedros, an Ethiopian doctor and diplomat, of failing to implement reforms.

Blaming China for the coronavirus, Trump, a frequent critic of the UN, said the United States would redirect funding "to other worldwide and deserving, urgent, global public health needs."

Democratic lawmakers have accused Trump of seeking to deflect criticism from his handling of the pandemic in the United States, which has suffered by far the highest death toll of any nation despite the president's stated hope that the virus will disappear.

"To call Trump's response to Covid chaotic and incoherent doesn't do it justice," said Senator Robert Menendez, the top Democrat on the Foreign Relations Committee.

"This won't protect American lives or interests -- it leaves Americans sick and America alone," he wrote on Twitter.

Representative Ami Bera, himself a physician, said that the United States and World Health Organization had worked "hand in hand" to eradicate smallpox and nearly defeat polio.

"Our cases are increasing," Bera said of Covid-19. "If the WHO is to blame: why has the US been left behind while many countries from South Korea to New Zealand to Vietnam to Germany return to normal?"

Even some of Trump's Republican allies had voiced hope that he was exerting pressure rather than making a final decision to abandon the World Health Organization.

The investigative news outlet ProPublica reported last month that most of Trump's aides were blindsided by the WHO withdrawal announcement, which he made during an appearance about China. 

The Trump administration has said that the WHO ignored early signs of human-to-human transmission in China, including warnings from Taiwan -- which, due to Beijing's pressure, is not part of the UN body.

While many public health advocates share some criticism of the WHO, they question what other options the world body had other than to work with China, where Covid-19 was first detected late last year in the city of Wuhan.

The anti-poverty campaign ONE said the United States should work to reform, not abandon, the WHO.

"Withdrawing from the World Health Organization amidst an unprecedented global pandemic is an astounding action that puts the safety of all Americans the world at risk," it said.

Mexico City, Jun 13: The number of people, who have died of COVID-19 in Mexico, has risen by 544 to 16,448 within the past 24 hours, Jose Luis Alomia, the director of epidemiology at the Health Ministry, said.

He also said on late Friday that the number of confirmed coronavirus cases had increased by 5,222 to 139,196 within the same period of time.

A day earlier, the Latin American nation has recorded 4,790 new confirmed cases of the coronavirus, with 587 fatalities.

The World Health Organization declared the COVID-19 outbreak a pandemic on March 11. To date, more than 7.6 million people have been infected with the coronavirus worldwide, with over 425,000 fatalities, according to Johns Hopkins University.
