The World Health Organisation's (WHO) team investigating the coronavirus' origins is not ruling out that the virus was already spreading in China as far back as October 2019, APA reports citing the Wall Street Journal.
According to the newspaper, some 90 people were hospitalised with coronavirus-like symptoms in central China in the two months before first cases were detected in the city of Wuhan. In the past few months, Chinese authorities tested two-thirds of these people for antibodies, but found no traces that they had had the virus.
The WHO investigators reportedly suggest that any antibodies could have dropped to undetectable levels due to time passed.
