WUHAN: A 20-year-old Chinese woman from Wuhan, the epicenter of the coronavirus outbreak, travelled 675km north to Anyang where she infected five relatives, without ever showing signs of infection, Chinese scientists reported on Friday (Feb 21), 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 more than 75,000 cases of the virus known as COVID-19 to the World Health Organization (WHO) including at least 2,000 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.

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.
