Authorities in the Chinese city of Wuhan have found no new confirmed Covid-19 cases, and 300 asymptomatic cases after city-wide testing was conducted for all 10 million of its population, Caixin reported.

China does not include asymptomatic cases in its tally of confirmed Covid-19 cases.

First city in China to conduct city-wide testing

The city has reportedly conducted the massive testing campaign between May 14 and June 1 -- the bill came close to RMB 900 million (S$177.1 million), which was fully paid for by the government.

The city was the first in China to roll out mandatory testing for every resident.

The goal of the campaign was to eliminate any hidden cases of Covid-19 to prevent its further spread.

300 people found to be asymptomatic carriers, but not infectious

Of the 10.9 million people who were tested, 300 people were tested positive for the virus but were all asymptomatic, the Hubei health commission said on Tuesday, June 2, at a press briefing.

They were not found to be infected nor proved to be infectious, the authority said.

In addition, it said all 1,174 people who had contact with the asymptomatic cases tested negative for the virus.

The city also reportedly took 2,315 environmental samples from public places such as buses, trains, shopping malls, parks and even pets.

All samples had tested negative.

Hubei's health commission announced that as of June 3, three Covid-19 patients are still in the midst of recovering, with one in critical condition.

Wuhan "safest city" in China now

According to Li Lanjuan, an epidemiologist at the National Health Commission, there is "little chance that people will be infected with the virus" in the city.

She said the data fully indicated that Wuhan is a safe city, and that it has "largely returned to normal".

Feng Zijian, a deputy director of China's national Centre for Disease Control and Prevention (CDC), also said that the city, once the pandemic's epicentre, is now the "safest city" in China.
