Shanghai announced similar restrictions as the city reported 65 new virus cases on Sunday, though it has not entered a complete lockdown. Instead, all residents are barred from leaving the city unless it is necessary to do so and must have a negative P.C.R. test as well.

Shanghai’s Disneyland also announced it is halting all of its theater shows and is requiring visitors to show negative results from a P.C.R. test taken in the preceding 24 hours, the Times reported.

This comes as China’s National Health Commission reported 3,122 new virus cases on Sunday, a rise from previous totals from 1,524 on Saturday and 1,100 on Friday, though still well below surges in other countries.

According to Johns Hopkins University, the average number of new virus cases has reached 1,370 per day in China over the past week.
