Wuhan, where the virus first emerged, so far had 50,340 confirmed coronavirus cases since January of which 3,869 people have died, according to the local health commission report.
The city conducted more than 60,000 nucleic acid tests on Sunday, finding no new asymptomatic cases, according to a statement issued Monday by the municipal health commission. Among them, two were reported in Sic-huan province, and one each in Shanghai, Guangdong and Shaanxi.
While asymptomatic Covid-19 carriers do not develop any of the typical coronavirus indicators, such as a fever, cough, or sore throat, they risk of spreading the disease to others.
The country's total number of confirmed cases now stands at 83,022, while the death toll remains unchanged at 4,634.
Since the start of the outbreak, Wuhan reported over 50,000 cases of the deadly infection.
The Chinese city of Wuhan, where the novel coronavirus outbreak began, has found no new cases of people suffering from COVID-19 after testing nearly its entire population, and 300 asymptomatic carriers of the virus, officials said on Tuesday.
Authorities launched the ambitious, city-wide testing campaign on May 14, and reached 9.9 million people, after a cluster of new cases raised fears of a second wave of infections. No confirmed cases of coronavirus were reported, senior officials said at a news conference on Tuesday in Wuhan.
The central Chinese city, which is the capital of Hubei province, was placed under a stringent lockdown on Jan 23. It was lifted on April 8.
The city's health commission said the tests are voluntary and free, with all costs borne by city and district governments.
