The epidemic situation in Sanya, Hainan spread and overflowed in the province. What are the characteristics of this epidemic?

It is characterized by strong aggregation and strong infectivity.

Aggregation is the main feature of local epidemic situation, and the emergence of local strains is a mysterious clonal mutation, which is first discovered in China and has many characteristics such as strong concealment and strong infectivity. According to the traceability investigation, it is found that Luzhou may come from fishing boats in fishing ports. When they went out to sea to trade with overseas fishing goods, the virus was introduced into Sanya. In view of this situation, the local authorities have also launched a large-scale investigation and disinfection of these fishing boats, hoping to curb the source of virus transmission.

There have been many cases of positive infection in this round of local epidemic. According to the local epidemiological investigation results, the confirmed cases have gone to other provinces, causing the epidemic to spread. The local disease control department has informed the disease control and epidemic prevention centers in other places to actively carry out investigations to prevent the epidemic from spreading in large areas. At present, corresponding measures have been taken there to keep residents as still as possible, and many local tourist attractions have also been suspended.

The clustering of this epidemic is particularly obvious, and the number of positive infected people is more than that of fishing boats, fishermen and fishing markets. At present, the clear communication chain spreads radially around Sanya Yazhou central fishing port. The epidemic situation is still on the rise, and there is a risk of community transmission in urban areas. In order to control the epidemic and prevent the epidemic from spreading in a large area, the local area has designated middle and high risk areas, and the residents in these areas have been managed by pulling nets and detecting all nucleic acids, so as to find the latent virus as soon as possible, and carry out isolation and effective treatment.

In order to cope with the epidemic prevention and control, many local tourist attractions have been temporarily closed, and those tourists stranded in the local area have also been properly resettled. If you want to leave, you must eat nucleic acid negative certificate twice for 48 hours. The entry and exit of local residents are flat, and the negative certificate and nucleic acid sampling record of the day are recorded in the account for 24 hours. Relevant departments have also issued a non-essential initiative, suggesting that gathering should be avoided as much as possible to prevent the epidemic from spreading again.
