Australia PM, Muslim leaders spar over his terror barb

Beijing, Jan 25: The death toll due to the novel coronavirus (2019-nCoV) outbreak in China has soared to 41, while the number of infected persons were 1,287, the National Health Commission said on Saturday.

The Commission said that 444 fresh cases were reported since Friday, with 237 patients in serious conditions, while 38 had been cured and discharged from hospitals, reports Efe news.

Health authorities have carried out check-ups on 15,197 people who have come into close contact with the infected persons. Nearly 14,000 of them continue to be monitored for symptoms.

The others cases outside of China were reported in France (two), Australia (one), Thailand (four including two cured), Japan (two including one cured), South Korea (two), the US (two), Vietnam (two), Singapore (three), Nepal (one), Hong Kong (five), Macao (two) and Taiwan (three).

The symptoms of the new coronavirus, provisionally designated by the World Health Organization as 2019-nCoV, are similar to those of cold but may be accompanied by fever and fatigue, dry cough and dyspnea (shortness of breath).

The WHO has so far to declared the outbreak as an international health emergency.

Strict measures were being carried out in China, which include complete suspension of transport in around a dozen cities in Hubei province and also cancelling Chinese New Year celebrations.

Traditional events at Lama Temple and Ditan Park in Beijing were cancelled due to the risk of spreading the virus, authorities reported Friday, while the famous Forbidden City has also been closed indefinitely.

Wuhan, the capital of Hubei, where the virus was first reported, has been on lockdown since Thursday to prevent further spread of the virus and the city's authorities have begun to build a "special hospital" with 1,000 beds for infected patients.

"Construction of the special hospital with a capacity of 1,000 beds for patients with #nCoV2019 has begun in Wuhan," official China Daily said on Twitter.

The hospital in Wuhan will be based on the model of a similar facility that was built in just seven days in Beijing to deal with SARS in 2003.

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.
