Shanghai Disneyland closed down temporarily on Sunday after it was discovered that a visitor had a positive COVID case. Nearly 34,000 other tourists on the premises had to be tested before leaving as part of China's strict COVID containment efforts.

The amusement park's forceful reaction to the singular positive case is in line with Beijing's "zero tolerance" policy approach to the disease that is reminiscent of Australia's, where COVID infections are tracked very closely among the population and lockdowns were reimposed well after many western countries lifted them. But while Australia has a 64.3 percent vaccination rate, China has an almost 80 percent vaccination rate.
