BEIJING, Apr 7 (.) – Mainland China on Tuesday reported a decline in new cases of coronavirus after closing its borders to virtually all foreigners in order to curb imported infections, while the central city of Wuhan, epicenter of the outbreak, did not record new deaths for the first time.

China had 32 new confirmed cases of coronavirus on Monday, down from 39 cases the previous day, the National Health Commission said.

The 32 cases affected travelers who arrived from abroad, compared to 38 cases imported the day before. The total number of imported infections so far is 983, according to the health authority.

Wuhan, capital of central Hubei province, reported only two new confirmed cases in the past 14 days. People are slated to leave town on Wednesday for the first time since it closed on January 23 to curb the spread of the virus.

After far exceeding the February peak of infections, the Chinese authorities have turned their attention to imported cases and asymptomatic patients, who do not show symptoms but can still transmit the virus.
