This field involves staff in many places. Secondly, a large number of residents in these places buy some fresh food every day, and these people live in different places, which has caused the widespread spread of this round of epidemic. Before the end of the epidemic in Guiyang City, Guizhou Province, Zunyi City, Guizhou Province ushered in a new epidemic. At present, static control has been implemented for medium-risk and high-risk areas, and the control has been lifted from 10 in September 2022 to 13 in September 2022.
So where did the epidemic in Zunyi City, Guizhou Province come from?
After the outbreak, the local authorities immediately carried out scientific prevention and control of this round of epidemic, decisively attacked and traced back to the source. According to the survey results of epidemic situation, the source of infection in this round of epidemic situation is outdoor, and according to the reported cases, they are all related to the wholesale market of Haifengjing in Honghuagang District. Because the virus in Zunyi City, Guiyang City and the virus prevalent in Guiyang City belong to the same sequence and have high homology, both of which are Omicron strain BA.2.76, it can be seen that there is a certain relationship with the transmission chain in Guiyang, because the wholesale market of Haifeng Well in Honghuagang District is related to the wholesale market of logistics in Huaxi District of Guiyang Flower Orchard. In response to this outdoor input, various departments have implemented control measures for relevant risk personnel. However, due to the large range of cases involved and the large number of people exposed, there is a certain risk of transmission. Therefore, according to experts' pre-judgment, two areas in Honghuagang District of Zunyi City are classified as high-risk areas, one as medium-risk areas and the rest as low-risk areas. At present, Zunyi City has adopted the method of cross nucleic acid detection for these high-risk urban areas.
