Shenzhen, the tech hub in southern China, has tightened its Covid-19 control policy, requiring a negative test result within 48 hours to enter subways and public venues, after three local asymptomatic cases were reported on Wednesday.
Starting from Friday, Shenzhen residents will need to present negative nucleic acid test results issued within 48 hours, or proof of a test taken within 24 hours, to ride the subway, use taxis and other public transport, or enter indoor premises, according to a notice issued by the local government on Thursday.
