Chengdu residents line up for COVID-19 testing

Mass testing continues in Chengdu, a city of 21 million people in southwestern China, following a spike in COVID-19 cases.

Authorities have locked down the city in an attempt to contain the spread and residents have been ordered to stay at home.

About 70% of the flights have been suspended to and from the city, which is a major transit hub in Sichuan province and a governmental and economic center.

Chengdu has reported around 1,000 cases in the latest outbreak and no deaths from the latest round of domestic transmission.

China says the measures are necessary to prevent a wider spread of the virus, which was first detected in the central Chinese city of Wuhan in late 2019.
