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.

An Indian Haj subsidy that did not exist!
Thank you Prime Minister Modi for ending Haj subsidy that never existed.
I completely welcome this move making the announcement, minister Mukhtar Abbas Naqvi said: “We believe in empowerment without appeasement.”Naqvi did not elaborate what he meant by “appeasement” but for decades, Haj subsidy remained a whip in the hands of right-wing parties to attack political rivals. Bharatiya Janata Party to embarrass rivals by accusing them of “appeasing” Muslims by subsiding expenses involved in the pilgrimage to Makkah and Madina. Angered by this attack, several Muslims have been demanding an end to the subsidy.
However, it is important to understand what this subsidy was and whether Muslims actually benefitted from it. In 2016-17, the government budgeted Rs 4.5 billion subsidy for around 100,000 Muslims who performed Haj last year. Each pilgrim paid around Rs 220,000 (amount varies each year) for airfare; stay in Makkah and Madina and for miscellaneous expenses. This money is paid to government-managed Haj committees which then transfers this money to other agencies. In other words, each Muslim pays for his/her own Haj expenses.
A significant chunk of money paid by Muslims goes to India’s government-owned national carrier Air India which enjoys a virtual monopoly on Haj circuit. The airline picks up passengers from around a dozen cities and flies them to Jeddah. The Air India inflates India-Jeddah tickets during the Haj season. This so-called government subsidy is used to pay for tickets that are always higher than the prevailing airfare charged by other airlines. A breakdown would show that an Air India ticket to Jeddah would cost more than a trip to Los Angeles from India. Essentially, the government takes money from one pocket and puts it back in another. Muslim have always demanded global tenders for Haj flights and for providing accommodation in Makkah and Madina..
However, while Naqvi sought to take a high moral ground by claiming that his party appeases no section of the society, his own government spends billions of rupees on organizing Hindu pilgrimages every year
Naqvi saab, this is what you learnt in Madrasa? U r Back-Stabbing Muslims. There is no 1% quality of muslim in you. After joining BJP you have lost it. First learn humanity. Almighty will give answers for all problems you have created for others.
