Beijing, Jan 21: The Chinese official investigating a pneumonia outbreak stemming from a new coronavirus said the disease can spread from person to person but can be halted with increased vigilance, as authorities on Tuesday confirmed a fourth death.

Zhong Nanshan said there was no danger of a repeat of the Severe Acute Respiratory Syndrome (SARS) epidemic that killed nearly 800 people globally during a 2002-2003 outbreak, which started in China, as long as precautions were taken.

"It took only two weeks to identify the novel coronavirus," state news agency Xinhua quoted Zhong as saying late on Monday.

The outbreak was still in its early stages and China had good surveillance and quarantine systems to help control it, he added.

The outbreak has spread from the central city of Wuhan to cities including Beijing and Shanghai, with more than 200 cases reported so far. Four cases have been reported outside China - in South Korea, Thailand and Japan.

Australia on Tuesday said it would screen passengers on flights from Wuhan amid rising concerns that the virus will spread globally as Chinese travellers take flights abroad for the Lunar New Year holiday starting this week.

Authorities around the globe, including in the United States and many Asian countries, have stepped up screening of travellers from Wuhan.

Chinese authorities confirmed a total of 217 cases of the virus in China as of 6 p.m. (1000 GMT) on Monday, state television reported, 198 of which were in Wuhan.

A fourth person died on Jan. 19, the Wuhan Municipal Health Commission said. The 89-year-old man, who had underlying health diseases including coronary heart disease, developed symptoms on Jan. 13 and was admitted to hospital five days later, it added.

Zhong, who is renowned in China for his work fighting SARS in 2003, confirmed that the virus can pass from person-to-person.

Fifteen medical workers in Wuhan had been diagnosed with pneumonia, with one other suspected case, the Wuhan Municipal Health Commission said. Of the infected staff, one was in critical condition.

In Shanghai, officials on Tuesday confirmed a second case involving a 35-year-man who had visited Wuhan in early January, and said they were monitoring four other suspected cases.

The virus causes a type of pneumonia and belongs to the same family of coronaviruses as SARS. Symptoms include fever and difficulty in breathing, which are similar to many other respiratory diseases and pose complications for screening efforts.

The World Health Organisation (WHO) said on Monday an animal source appeared most likely to be the primary origin of the outbreak and that some "limited human-to-human transmission" occurred between close contacts.

The Geneva-based U.N. agency convened an emergency committee for Wednesday to assess whether the outbreak constitutes an international health emergency and what measures should be taken to manage it.

So far, the WHO has not recommended trade or travel restrictions, but a panel of independent experts could do so or make other recommendations to limit spread.

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.

Beijing, Mar 24:  China reported 78 new confirmed cases, including 74 imported infections, while the death toll from the novel coronavirus increased to 3,277 after seven more fatalities were confirmed from the COVID-19, health officials said on Tuesday.

The overall confirmed cases on the Chinese mainland have reached 81,171 by the end of Monday. This included 3,277 people who died of the disease, 4,735 patients who were still being treated and 73,159 patients discharged after recovery, the National Health Commission (NHC) said on Tuesday.

The NHC said, 78 new confirmed COVID-19 cases were reported on the Chinese mainland on Monday, of which 74 were imported from abroad taking the number of overseas cases to 427.

Also on Monday, seven deaths and 35 new suspected cases were reported on the mainland with all the deaths in Hubei Province.

The total COVID-19 cases in Beijing climbed to 522 with eight deaths prompting local governments of Beijing as well as Shanghai to announce that all overseas arrivals will be subjected to nucleic acid tests to ensure proper detection.

Of the 74 newly imported cases, 31 were reported in Beijing, 14 in Guangdong, nine in Shanghai, five in Fujian, four in Tianjin, three in Jiangsu, two in Zhejiang and Sichuan respectively, and one in Shanxi, Liaoning, Shandong and Chongqing respectively, the NHC said.

Beijing is already diverting all international flights to different cities where the passengers will be quarantined for 14 days before arriving in the city.

The NHC said 132 people were still suspected of being infected with the virus.

Coronavirus epicentre Wuhan has reported one confirmed case after a gap of five days prompting officials to begin to ease restrictions.

Wuhan also reported seven new deaths, bringing the total number of deaths in the city and Hubei province for which Wuhan is the capital to 3,160.

The province also saw 444 patients discharged from hospital after recovery on Monday. Among the 4,200 patients being treated in hospital, 1,203 were still in severe condition and another 336 in critical condition, the local health commission said.

By the end of Monday, 356 confirmed cases, including four deaths have been reported in Hong Kong, which has restricted the entry of foreigners into the city. Also a total of 25 confirmed cases were reported in Macao and 195 in Taiwan including two deaths, state-run Xinhua news agency reporrted.

After days of decline in coronavirus cases, China on Monday said that COVID-19 has effectively been "stemmed" in the country and it started easing severe restrictions imposed on Wuhan's 11 million people who were under lockdown since January 23.

The authorities began relaxing restrictions in Wuhan as it reported no new case for the fifth consecutive day on Monday.

Significantly, the Central Leading Group (CLP), headed by Premier Li Keqiang which is coordinating efforts to contain the virus since January 23, said the virus has been curtailed in the country as well as in Wuhan.

"The meeting noted that the spread of the virus nationwide, particularly in the epicentre of Wuhan, has been effectively stemmed," an official statement said on Monday.

The meeting, however, warned that the risks for sporadic infections and localised outbreaks have not gone away. With the pandemic rampaging across the world, the situation remains complex and challenging.

"Wuhan city and Hubei province should stay focused on medical treatment and community-level containment as the two key priorities. They should continue to treat the severe cases, promptly admit new cases, and advance epidemiological investigations," the meeting said.

In Wuhan, officials said people are allowed to go back to work while restrictions on the public transport are gradually being eased.

The Hubei province and its capital Wuhan with over 56 million people were under lockdown since January 23. The vicious virus broke out in city, reportedly at a live animal market in December last year and became virulent inflicting thousands of people in the city and province catching the government off guard.

As the country saw a surge in imported infections, the Chinese government announced that all international flights scheduled to arrive in Beijing will be redirected to airports in 12 other Chinese cities from Monday.

International passengers flying to Beijing will instead land at airports in 12 cities including Shanghai, Tianjin, Nanjing and Shenyang as their first points of entry, the Civil Aviation Administration of China (CAAC) said in a statement.

On Monday, China said international travellers should "think twice" about choosing Beijing for flight transfer in view of the restrictions.

Starting from Monday, all international flights scheduled to arrive in Beijing will be redirected to airports in 12 other Chinese cities, Liu Haitao, an official with China's National Immigration Administration said.

Passengers would go through entry procedures and quarantine measures at the designated cities' airports before they continue their flights to Beijing, Liu said, urging travellers to reserve enough time for their next flights to make sure that they do not miss their outbound flights.
