Jun 13: Requiring the wearing of masks to prevent the spread of the novel coronavirus in areas at the epicenter of the global pandemic may have prevented tens of thousands of infections, a new study suggests.

Mask-wearing is even more important for preventing the virus' spread and the sometimes deadly COVID-19 illness it causes than social distancing and stay-at-home orders, researchers said, in the study published in PNAS: The Proceedings of the National Academy of Sciences of the USA.

Infection trends shifted dramatically when mask-wearing rules were implemented on April 6 in northern Italy and April 17 in New York City - at the time among the hardest hit areas of the world by the health crisis - the study found.

"This protective measure alone significantly reduced the number of infections, that is, by over 78,000 in Italy from April 6 to May 9 and over 66,000 in New York City from April 17 to May 9," researchers calculated.

When mask-wearing went into effect in New York, the daily new infection rate fell by about 3% per day, researchers said. In the rest of the country, daily new infections continued to increase.

Direct contact precautions - social distancing, quarantine and isolation, and hand sanitizing - were all in place before mask-wearing rules went into effect in Italy and New York City. But they only help minimize virus transmission by direct contact, while face covering helps prevent airborne transmission, the researchers say.

"The unique function of face covering to block atomization and inhalation of virus-bearing aerosols accounts for the significantly reduced infections," they said. That would indicate "that airborne transmission of COVID-19 represents the dominant route for infection."

The U.S. Center for Disease Control and Prevention on Friday urged organizers of large gatherings that involve "shouting, chanting or singing to strongly encourage the use of cloth face coverings to lower the risk of spreading the coronavirus."

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.

Feb 11: China reported 108 new coronavirus deaths on February 10, the highest daily toll since the outbreak began in Wuhan late last year, as two senior officials in the hard-hit province of Hubei were removed from their jobs.

The total number of deaths on the mainland reached 1,016 in the 24 hours until midnight, the National Health Commission said on Tuesday.

Some 2,478 new cases were confirmed, bringing the total to 42,638.

Of the new deaths, 103 were in the province of Hubei, including 67 in the provincial capital of Wuhan. The virus is thought to have originated there in a market that sold seafood as well as wild animals.

Two senior health officials in the province - Zhang Jin who was Party Secretary of the health commission for Hubei and Ling Yingzi who was director of the Hubei Provincial Health Commission - were both removed from their posts, state media reported on Tuesday,  a day after Chinese President Xi Jinping visited health facilities in Beijing.

In his first public appearance since the outbreak began, Xi donned a face mask and had his temperature checked while visiting medical workers and patients in the capital.

"We have seen very little of Xi Jinping since the outbreak began but he was out and about in Beijing on Monday," Al Jazeera's Katrina Yu said from Beijing. "He has been trying to rally the troops saying: 'We can win this battle.' But it's also a sign that the battle is far from over."

The other fatalities on Monday were in the provinces of Heilongjiang, Anhui and Henan and the cities of Tianjin and Beijing, the National Health Commission said.

During a meeting chaired by Premier Li Keqiang on Monday, a group of leaders tasked with beating the virus said it would work to solve raw material and labour shortages and boost supplies of masks and protective clothing.

They said nearly 20,000 medical personnel from around the country had already been sent to Wuhan, and more medical teams were also on the way.
