The reporter learned from the press conference on epidemic prevention and control in Xiamen, Fujian that in this epidemic, the transmission capacity of cases is very strong, and many close contacts or exposed personnel have been infected at the same time.
The sequencing results of the virus genome by Xiamen Center for Disease Control and Prevention showed that the virus was typed as Omicron variant BA.2.76.
According to public information at home and abroad, this variant is a subtype of strain with stronger transmission ability than the Omicron variant BA.5.
In the current epidemic in Xiamen, the mutant strain has the characteristics of fast transmission, strong infectivity and strong concealment.
From exposure to the virus to the detection of positive nucleic acid sampling, some people need 1 day, and some people need 3 days, 4 days, or even longer.
In order to effectively detect new coronavirus infected people hiding in the community, it is necessary to carry out multiple rounds of nucleic acid testing in a row.
During the epidemic prevention and control period, citizens and friends are requested to strengthen personal protection, pay attention to wearing masks scientifically, wash hands frequently, and do not gather.
