About half of the cases are caused by meals

There is a risk of spillover from the spread of the outbreak
About 80% of the infected people in this epidemic live in the same natural village, the spatial aggregation is obvious, the community has a long hidden transmission time, the trajectory of personnel activities is large, coupled with the large mobility of personnel during the Spring Festival, the risk of further spread is relatively high, and it is necessary to complete the screening and control of risk personnel, accelerate the speed of nucleic acid screening, and find the source of infection in the community as soon as possible.
He Qinghua stressed that the spillover cases from Bose to Nanning, Guangxi and Guangzhou, Guangdong, had many trajectories before being controlled, and there was a risk of spillover from the spread of the epidemic.
