The scale of the Covid-19 outbreak in Wuhan early this year may have been nearly 10 times the recorded tally, a study conducted by China’s public health authorities indicates, leaving the city where the coronavirus first took hold still well short of the immunity required to protect against a potential resurgence.
About 4.4% of those tested were found to have specific antibodies that can fight off the pathogen that causes Covid-19, indicating they were infected some time in the past, according to a serological survey of more than 34,000 people conducted in April by the Chinese Center for Disease Control and Prevention. The data was released late Monday.
