Shanghai Disney Resort suspended operations on Monday to comply with COVID prevention measures after the city recorded 10 new cases.

The resort said it was immediately shutting its main theme park and surrounding areas and the Shanghai government said all guests would have to provide a negative COVID test before they were allowed to leave, Reuters reported.

Anyone who had visited the park since 27 October would need to test for COVID-19 three times in three days, it added.

According to social media reports, the theme park continued to operated rides for those stuck in the park.

Videos on China’s Weibo platform showed people rushing to the park’s gates after hearing about the new COVID prevention measures, but the gates were already locked.

The resort later reported that everyone had tested negative and had been allowed to leave.

No date has been given for when the park will reopen.

This is the second time in a year that the park has unexpectedly shut suddenly because of COVID. Last November, the gates were shut on 30,000 people after authorities ordered everyone to be tested as part of contact tracing.
