London, Mar 27:  British Prime Minister Boris Johnson said Friday he has tested positive for the new coronavirus, but remains in charge of the U.K.'s response to the outbreak.

Johnson's office said he was tested on the advice of the chief medical officer after showing mild symptoms.

It said Johnson is self-isolating at his 10 Downing St. residence and continuing to lead the country's response to COVID-19.

In a video message, Johnson said he had a temperature and a persistent cough.

Over the last 24 hours I have developed mild symptoms and tested positive for coronavirus.

I am now self-isolating, but I will continue to lead the government’s response via video-conference as we fight this virus.

"Be in no doubt that I can continue, thanks to the wizardry of modern technology, to communicate with all my top team, to lead the national fightback against coronavirus."

Earlier this week Britain’s Prince Charles announced that he had tested positive for the virus.

Geneva, Jul 4: The World Health Organization has updated its account of the early stages of the COVID crisis to say it was alerted by its own office in China, and not by China itself, to the first pneumonia cases in Wuhan.

The UN health body has been accused by US President Donald Trump of failing to provide the information needed to stem the pandemic and of being complacent towards Beijing, charges it denies.

On April 9, WHO published an initial timeline of its communications, partly in response to criticism of its early response to the outbreak that has now claimed more than 521,000 lives worldwide.

In that chronology, WHO had said only that the Wuhan municipal health commission in the province of Hubei had on December 31 reported cases of pneumonia. The UN health agency did not however specify who had notified it.

WHO director Tedros Adhanom Ghebreyesus told a press conference on April 20 the first report had come from China, without specifying whether the report had been sent by Chinese authorities or another source.

But a new chronology, published this week by the Geneva-based institution, offers a more detailed version of events.

It indicates that it was the WHO office in China that on December 31 notified its regional point of contact of a case of "viral pneumonia" after having found a declaration for the media on a Wuhan health commission website on the issue.

The same day, WHO's epidemic information service picked up another news report transmitted by the international epidemiological surveillance network ProMed -- based in the United States -- about the same group of cases of pneumonia from unknown causes in Wuhan.

After which, WHO asked the Chinese authorities on two occasions, on January 1 and January 2, for information about these cases, which they provided on January 3.

WHO emergencies director Michael Ryan told a press conference on Friday that countries have 24-48 hours to officially verify an event and provide the agency with additional information about the nature or cause of an event.

Ryan added that the Chinese authorities immediately contacted WHO's as soon as the agency asked to verify the report.

US President Donald Trump has announced that his country, the main financial contributor to WHO, will cut its bridges with the institution, which he accuses of being too close to China and of having poorly managed the pandemic.

The WHO denies any complacency toward China.

Feb 22: A 20-year-old Chinese woman from Wuhan, the epicentre of the coronavirus outbreak, travelled 400 miles(675 km) north to Anyang where she infected five relatives, without ever showing signs of infection, Chinese scientists reported on Friday, offering new evidence that the virus can be spread asymptomatically.

The case study, published in the Journal of the American Medical Association, offered clues about how the coronavirus is spreading, and suggested why it may be difficult to stop.

"Scientists have been asking if you can have this infection and not be ill? The answer is apparently, yes," said Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, who was not involved in the study.

China has reported a total of 75,567 cases of the virus known as COVID-19 to the World Health Organization (WHO) including 2,239 deaths, and the virus has already spread to 26 countries and territories outside of mainland China.

Researchers have reported sporadic accounts of individuals without any symptoms spreading the virus. What's different in this study is that it offers a natural lab experiment of sorts, Schaffner said.

"You had this patient from Wuhan where the virus is, travelling to where the virus wasn't. She remained asymptomatic and infected a bunch of family members and you had a group of physicians who immediately seized on the moment and tested everyone."

According to the report by Dr Meiyun Wang of the People's Hospital of Zhengzhou University and colleagues, the woman travelled from Wuhan to Anyang on Jan. 10 and visited several relatives. When they started getting sick, doctors isolated the woman and tested her for coronavirus. Initially, the young woman tested negative for the virus, but a follow-up test was positive.

All five of her relatives developed COVID-19 pneumonia, but as of Feb. 11, the young woman still had not developed any symptoms, her chest CT remained normal and she had no fever, stomach or respiratory symptoms, such as cough or sore throat.

Scientists in the study said if the findings are replicated, "the prevention of COVID-19 infection could prove challenging."

Key questions now, Schaffner said, are how often does this kind of transmission occur and when during the asymptomatic period does a person test positive for the virus.
