The first recent COVID-19 case was reported on Hainan on August 1, after which the coronavirus spread to over ten cities on the island.
As of Monday morning, there have been over 980 confirmed COVID-19 cases on Hainan and nearly 450 asymptomatic cases. No deaths have been reported.
Most of the cases have been registered in the resort city of Sanya, where a lockdown has been in effect since Saturday.
Tourists are not allowed to leave Sanya unless they get two negative COVID-19 test results within 48 hours. Hainan residents are allowed to leave the island only in case of emergency.
According to Chinese health authorities, the new omicron subvariant BA.5.1.3, which could have been imported to the island with frozen seafood, accounts for the majority of cases in Hainan.
