How was the Haikou epidemic caused?

In early August, 2022, Haikou reported the first confirmed case of COVID-19. Subsequently, the virus spread, and an epidemic occurred in three cities and counties in Hainan Province/KLOC-0, including seven cities and counties in Sanya, and the epidemic spread in communities. Li Wenxiu, deputy head of the medical treatment team of COVID-19 Epidemic Prevention and Control Command, Hainan Province, said that the virus strain that caused the current epidemic in Hainan was the first reported strain of Omicron BA5 13 in China. The new mutant has the characteristics of strong infectivity, rapid spread and strong concealment, which increases the difficulty of epidemic prevention and control.

In order to prevent the spread of the epidemic, Haikou has implemented temporary global static management since August 6, 2022, and many other cities and counties related to the epidemic have also implemented temporary static management. The sudden epidemic disrupted the itinerary of passengers, and a large number of passengers were stranded in Hainan.
