A cluster of cases within a family living in the Chinese city of Anyang is believed to have begun when a 20-year-old woman carried the virus from Wuhan, the outbreak’s epicentre, on January 10 and spread it while experiencing no illness, researchers reported in the Journal of the American Medical Association.
Five relatives subsequently developed fever and respiratory symptoms.
Although coronavirus is less deadly than SARS, which had a case fatality rate of 9.5 percent, the disease is likely more contagious.
Both viruses attack the respiratory and gastrointestinal tracts, via which they can potentially spread.
