(Fighting against New Coronary Pneumonia) The average incubation period of this round of epidemic in Guangzhou is less than 2 days
China News Agency, Guangzhou, September 1 (Reporter Wang Hua) The Guangzhou Municipal Health Commission announced on the 1st that there were 9 new cases of local new coronavirus infections in the city.
Epidemiological data shows that so far, the transmission chain of this epidemic is clear, and it is inseparable from the "swimming pool"; and the transmission speed is extremely fast, with an average incubation period of less than 2 days.
From 11:00 on August 31 to 8:00 on September 1, 9 new cases of local new coronavirus infection in Guangzhou were found in the close inspection.
Among them, 5 cases were the co-exposed persons of the infected person in the swimming place announced the previous day; 3 cases were the family members of the infected person announced the previous day; 1 case was a close contact.
The above 9 infected persons have been closed-loop transferred to the hospital for centralized isolation and medical observation.
After diagnosis, 4 cases were asymptomatic infections and 5 cases were mild cases of new coronary pneumonia.
The current condition is stable.
Since August 30, a total of 16 infected people have been reported, involving many places and a wide range. Some cases have caused secondary infections in family members.
Guangzhou is making every effort to carry out prevention and control work.
The city's epidemic-related sites involve a total of 85 points in 7 districts, and a total of more than 5,300 key populations have been screened, all of which have been included in health management.
From 8:00 on August 31 to 8:00 on September 1, 7.665 million nucleic acid samples were sampled and tested in the city. Except for the infected person announced on the 1st, the rest were negative.
The Guangzhou Center for Disease Control and Prevention pointed out that so far, the transmission chain of the epidemic is very clear, and most of the 16 positive cases were either common exposure in swimming pools or family transmission caused by exposure to swimming pools.
At the same time, it was also found that the epidemic spread very fast. The index case developed on August 27. In just 5 days, it has developed to the 4th generation. The latest reported case has spread from social activities after swimming pool exposure. The average incubation period is 1.9 days (that is to say, one generation can be transmitted in less than 2 days). Therefore, in the face of Omicron, the treatment speed should be faster and the prevention and control measures should be more decisive.
September 1 is the first day of the new school year for primary and secondary schools and kindergartens in Guangzhou.
In the morning, except for individual schools and kindergartens in Haizhu District and other risk areas, other schools have started as scheduled.
Primary and secondary schools and kindergartens in Haizhu District suspend their return to school and offline teaching, off-campus training institutions suspend offline teaching, and childcare and trustee institutions suspend services.
The Guangzhou Education Bureau stated that at the beginning of the school year, teachers and students returned to school with a 48-hour nucleic acid test negative certificate, and normalized nucleic acid test requirements were implemented after returning to school.
In the next step, we will work with the health and disease control departments to study and judge the impact of the epidemic on the start of the autumn semester in a timely manner, and adjust the teaching arrangements and prevention and control measures in a timely manner.
