Q&A: Is repeated mass COVID testing necessary in Shanghai?

Q: How can large-scale testing be made more convenient and efficient?

A: Shanghai has asked all districts to determine their exact resident populations through grid screening, and appropriately allocate medical staff to conduct tests, Wu said.

The city's testing capacity has been enhanced after air-inflated laboratories and mobile nucleic acid testing vehicles have been put into use.

At present, the maximum daily nucleic acid testing capacity in Shanghai has reached 5 million tubes.
