Arrivals to Shenzhen who have been to medium- and high-risk areas for COVID-19 should report to their communities, companies or hotels as soon as possible, Shenzhen Center for Disease Control and Prevention (CDC) said Sunday.

Those who have traveled to the cities of Heihe in Heilongjiang Province since Oct. 13 and Shangrao in Jiangxi Province since Oct. 16, and arrivals and returnees from Gansu Province and the Inner Mongolia Autonomous Region are recently required to report to the authorities, according to the CDC.

These arrivals are also required to comply with the city’s epidemic prevention and control measures such as nucleic acid testing, medical observation or health monitoring.

Additionally, the city’s COVID-19 prevention and control authorities also urged arrivals from Shanghai Disneyland and Disneytown between Saturday and Sunday to report to their communities, companies or hotels. They must also undergo a seven-day quarantine and a seven-day health monitoring at home, and take respective nucleic acid tests on the first, fourth, seventh and 14th day.
