165438+ 10 month 14 0: 00, 3 1 provinces and Xinjiang production and construction corps reported 52 new confirmed cases. Among them, 32 cases were diagnosed locally, including 12 cases which were converted from asymptomatic infected persons to confirmed cases.
In view of the rapid increase in the number of positive infections in Dalian, especially in recent days, there are two main reasons for the analysis of Dalian CDC:
First, the COVID-19 involved in this epidemic belongs to Delta variant. At present, all the strains in gene sequencing are in the same transmission chain, and it is judged that the same strain is a local aggregation epidemic, which has low homology with the recent local epidemic in China and the COVID-19 genome entered into the case database. The epidemic spread index is high, infectious and the incubation period is short. Nearly 300 cases were reported in just five days and ten days, and the number of cases increased rapidly, which is the characteristic of this Delta variant.
Second, the epidemiological investigation found that the epidemic situation was hidden, and most of the infected people had no obvious symptoms in the early stage. In Dalian Keqiang Food Co., Ltd., Haikuo Food Co., Ltd., Shengfeng Market and other places, a cluster epidemic situation and a number of family cluster diseases were formed, and many cases were reported in schools, causing a certain range of community transmission. The characteristics of epidemic clustering and the emergence of super communicators have led to a rapid increase in the number of cases.
According to the epidemiological information of confirmed cases, the first confirmed case of this round of epidemic in Dalian came from the designated cold storage in zhuanghe city, the first stop. Cold storage employees were diagnosed, followed by food company employees, followed by college students in the canteen.
Beijing Keyuan Community tested positive for an express parcel from Inner Mongolia.

Taizhou CDC once again reminded couriers and citizens to pay attention to:
First, during the epidemic prevention and control period, do not mail-order goods from overseas high-risk areas, and carefully mail-order goods from areas with local epidemic reports in China.
Second, couriers should strengthen health management to ensure that they are not infected and do not go to work with illness; Do a good job in protecting the express delivery during transportation, and the packaging should not be directly exposed.
Third, the general public should take proper protection when receiving express delivery, wear masks and gloves, and keep a distance of one meter from the personnel. The surface packaging of express delivery is not brought indoors. When it is really necessary to bring it in, it can be wiped on six sides with disinfectant wipes or sprayed for disinfection. Be sure to do hand hygiene after handling the courier.
