The popular Omikon BA.5.2 mutant strain in Xinjiang presents four characteristics

On the evening of September 3, the Press Office of the People's Government of the Autonomous Region held a press conference on epidemic prevention and control. At the meeting, Ni Mingjian, the chief expert of the CDC Center of the Autonomous Region, introduced the characteristics of this round of epidemic virus and the challenges brought to the prevention and control of the epidemic.

The popular Omikon BA.5.2 mutant plant has several characteristics: First, the CT value of the infected nucleic acid CT is generally low, and nearly 70%of the infected persons have the first nucleic acid detection N target, ORF1AB target CT value is 10 Between -25, it is prompted to have a high load and strong infectivity. The second is that the average incubation period is short. The average incubation period of Omikon BA.5 in China is 2-4 days. The incubation period of the observation of the epidemic in our district is close to it, with an average of 2-3 days. The proportion of symptoms infected is high, and a small number of infected people have a positive time lag lag at the time of onset, which leads to the difficulty of early detection and early control of cases. Third, the community is more common. Since the static management on August 10, there are 1,527 cases of infected people in the static management zone of the district (excluding the Corps), of which 57.56%of the infected people reported after 7 days; In the report cases, there were 56 reports of the first case from the epidemic district, which involved 163 infected people, accounting for 38.7%of the number of social reports. The fourth is obvious onset of clustering. As of August 31, there were 73 gathered epidemic in the report venues in the region, involving 2609 people, accounting for 47.6%. Family clustered epidemic was 773, involving 281 people, accounting for 38.1%. These characteristics have increased the complexity and uncertainty of this epidemic, which leads to the continuous increase in the prevention and control of the epidemic.
