(Fighting against New Coronary Pneumonia) Guangzhou Baiyun Airport Epidemic is an Overseas Import-related Epidemic
China News Agency, Guangzhou, April 29 (Wang Hua and Zhang Hengyuan) The Guangzhou Municipal Health Commission announced on the 29th that the local epidemic found at Guangzhou Baiyun International Airport, after epidemiological investigation and laboratory gene sequencing comparison, showed that it was An independent overseas import-related epidemic was initially judged to be caused by accidental exposure of airport staff at work.
From 12:00 on April 28 to 12:00 on April 29, 20 new local positive infections of the new coronavirus were added in this outbreak; among them, 12 were confirmed cases and 8 were asymptomatic infections.
The above 20 cases of infection were found in the close contacts of the isolation places, key groups and control areas.
Up to now, a total of 24 cases of infection have been reported in this outbreak, all of which are asymptomatic or mild.
The epidemic mainly occurred in the airport and surrounding areas, and the related flow tracing work is still in progress.
Zhang Zhoubin, a spokesman for the Guangzhou Center for Disease Control and Prevention, said that the virus gene sequencing result of the epidemic is the evolutionary branch of Omicron BA.2, which is quite different from the mutation site of the previous domestic epidemic infection, but it is different from a recent entry infection. The sequences are highly homologous, "combined with epidemiological investigations, this outbreak is an independent overseas imported related outbreak, which is initially judged to be caused by accidental exposure of airport staff."
Zhang Zhoubin said that in this epidemic, the airport staff were all negative in the routine nucleic acid test on April 25. In just two days, a large number of infected people appeared, which fully reflects the mutation of Omi Keron. The characteristics of the strains are highly contagious, fast in transmission, and short in incubation period. This also reminds once again that personal protection should be placed in the most important position.
As of 12:00 on the 29th, Guangzhou has screened 1,405 close contacts and 753 sub-close contacts, 3,468 key personnel, and a total of 15.07 million nucleic acid samples; 545 environmental samples, of which 4 were positive, were infected found in the person's home or work environment.
