China Is Said to Let Some Cities Like Shanghai, Guangzhou Shorten Quarantines

China is allowing Shanghai, Guangzhou and six other cities to shorten quarantines for overseas travelers and those who’ve had close contact with infected individuals as authorities test potential tweaks to the country’s rigorous Covid measures, according to people familiar with the matter. The cities are reducing the period to 10 days from 14 days as part of a trial that began on Monday this week and will run for a month, the people said, asking not to be identified as they weren’t authorized to discuss the issue publicly. Apartment complexes, retail outlets, office buildings and other locations locked down because of infections will also be allowed to open after 10 consecutive days without a positive test result, shortened from the 14 days previously required, they said.
