All cases were mild, and no new asymptomatic local cases had been reported.Lou Xiaoming, deputy director of the Zhejiang Center for Disease Control and Prevention, said at a press conference that from the current epidemiological investigation and analysis, the transmission chain of the outbreak should be relatively clear.As of 12 noon today, of all the positive cases, 16 are huierte employees, the rest are direct or indirect contact with employees.Sequencing of the first case also revealed a clade of BA1.1.The homology of the virus genome was low by comparison between China CDC and other provinces in China.Compared with the global comparison, it is highly consistent with the foreign report on December 11, 2021.Of the 11 tested samples, 4 were positive for Omicron, indicating the possibility of transmission from person to person.We have preliminarily determined that the mode of transmission of the epidemic is from objects to people, and then from specific activities of people.Wang Xuchu, deputy director of hangzhou Municipal Health Commission, said 30 local confirmed cases had been reported.Among them, 3 cases were hospitalized voluntarily, 4 cases were detected by screening in the containment area and control area, and 23 cases were detected by testing at isolation points.Among the 30 cases, 15 were employees of Huite Catering Equipment Co., LTD., and there were 4 cases of family clustering, involving 9 people.Seven of those who attended a wedding banquet were found to be infected, and another seven were found to live or work in The Xiyuan community of Changjiang River in Binjiang District, showing a certain degree of clustering.At present, there is 1 risk area in the city, and classified control measures and environmental disinfection have been taken in all relevant epidemic-related sites.According to the epidemiological investigation, experts concluded that the transmission chain of this round of epidemic is relatively clear and the overall risk is controllable, but there may still be multiple positive cases in the future.The main reasons are as follows: First, the earliest onset of illness of positive infected persons is January 20, and most of them are between 20 and 25.Therefore, it is inferred that the first case is the third generation, and it is estimated that the virus was introduced in early January.Second, half of the cases were workers of Huite Catering Co., LTD., with a long interval, the virus has already spread within the company, and there may still be further cases.Thirdly, there are many cases of the company living in the changhe community of Binjiang District. The possibility of further cases in the community cannot be ruled out.Fourthly, seven cases have been detected among those who attended the wedding on 24 January.The wedding became a magnified venue for the outbreak.
