TOKYO (Reuters) - A survey of Line Corp's 3938.T chat app users in Tokyo and neighboring prefectures in partnership with Japan's health ministry found 7.1% of respondents in the capital reporting at least one of the symptoms of the coronavirus.

A total of 443 people in Tokyo are infected with coronavirus according to official figures. Line’s survey found that 7.1% out of 63,843 people responding in Tokyo reported at least one of the symptoms of the virus, including high fever or a bad cough, between March 27-30.

That puts the number of people reporting symptoms from a limited sample at around 4,500, although having such symptoms does not prove coronavirus infection and the respondees were self-selecting.
