Russia reports over 6,800 new COVID-19 cases as total nears 628,000

Beijing, Feb 18: A hospital director at the epicentre of China's virus epidemic died on Tuesday, state media said, the latest medical worker to fall victim to the new coronavirus spreading across the country.

The COVID-19 virus, which is believed to have originated in Wuhan late last year, has infected more than 72,000 people and killed nearly 1,900.

Liu Zhiming, the director of Wuchang Hospital in Wuhan, died Tuesday morning after "all-out rescue efforts failed," state broadcaster CCTV reported.

China said last week that six medical workers had died from the virus, while 1,716 have been infected.

Liu's death was initially reported by Chinese media and bloggers shortly after midnight on Tuesday -- but the stories were later deleted and replaced with reports that doctors were still trying to save him.

After initial reports of his death were denied, the hospital told AFP on Tuesday morning that doctors were giving him life-saving treatment.

Liu's death has echoes of that of Wuhan ophthalmologist Li Wenliang, who had been punished by authorities for sounding the alarm about the virus in late December.

Li's death prompted a national outpouring of grief as well as anger against the authorities, who were accused of mishandling the crisis.

People took to social media to mourn Liu on Tuesday, with many users on the Twitter-like Weibo platform drawing critical comparisons between Liu's death and Li's.

In both cases their deaths were initially reported in state media posts -- later deleted -- and their deaths denied, before being finally confirmed again.

"Has everyone forgotten what happened to Li Wenliang? They forcefully attempted resuscitation after he died," one Weibo commenter wrote.

Another commenter said, Liu "already died last night, (but) some people are addicted to torturing corpses".

A hashtag about Liu's death had 29 million views by Tuesday afternoon.

Doctors in Wuhan face shortages of masks and protective bodysuits, with some even wearing makeshift hazmat suits and continuing to work despite showing respiratory symptoms, health workers have told AFP.

Hubei province and its capital Wuhan have been the hardest hit by the virus, accounting for nearly 1,800 of the deaths from the virus so far.

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.
