The city of Wuhan in central China, where the coronavirus was first detected at the end of last year, said it had tested nearly 10 million residents in an unprecedented campaign of 19 days to check an entire city.

The effort identified only 300 positive cases, none of which showed symptoms. None of the 1174 people identified as close contacts of these patients were found to have the disease, suggesting that they did not easily spread it to others.

This is a potentially encouraging development due to the widespread concern that infected people without symptoms may be silent spreaders of the disease.

There is not yet a definitive answer on the level of risk posed by asymptomatic cases, with anecdotal evidence and studies to date producing contradictory answers.

A city official announced on Tuesday that the city had carried out 9.9 million tests from May 14 to June 1.
