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

Q: How can infection be prevented during large-scale testing?

A: Shanghai has called for residents to receive COVID-19 tests in batches or at staggered times, or to visit sites only when called to avoid infection, said Wu Qing, executive vice-mayor of Shanghai.

Residents have also been told to maintain a distance of 2 meters with each other, wear a mask and refrain from talking during the testing process.
