Shanghai to lock down in two stages for testing as COVID cases spike

China's financial hub of Shanghai said on Sunday it would lock down the city in two stages to carry out COVID-19 testing over a nine-day period, after it reported a new daily record for asymptomatic infections. Authorities said they would divide Shanghai into two for the exercise, using the Huangpu River that passes through the city as a guide. Districts to the east of the river, and some to its west, will be locked down and tested between March 28 and April 1. The remaining areas will be locked down and tested between April 1 and 5.
