A 20-year-old Chinese woman from Wuhan, the epicentre of the coronavirus outbreak, travelled 675km (400 miles) north to Anyang where she infected five relatives, without ever showing signs of infection, Chinese scientists reported, offering new evidence that the virus can be spread asymptomatically.
According to the report by Dr Meiyun Wang of the People’s Hospital of Zhengzhou University and colleagues, doctors isolated the woman and tested her for the virus after her relatives started getting sick.
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 February 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.
