One flight 3 pass 36!Expert: This reason will be accelerated!

Since August 12, since the emergency response to the immune -related flights from foreign provinces, as of 16:00 on August 18, the input -input epidemic has reported 61 positive infections. The virus gene sequences are BA.2.76 mutant strains.

On August 19, Zeng Daxian, the leader of the Wenzhou epidemic prevention and control expert group, said in an interview that combined with the epidemic situation across the country, the BA.2.76 mutant strain is currently the most contagious and fastest transmission strain. Among the "8.12 province's input epidemic" in Wenzhou City, three positive infected people on a plane transmitted 36 same flight personnel.

You can spread a generation in less than 2 days

Infected 1-2 days after being infected

Zeng Diandian said that the most obvious feature of BA.2.76 compared to other mutant strains in Omikon is: stronger infectious power and faster dissemination.

Judging from the situation of immune -related flights, three positive infected people were infected with 36 people on the same aircraft, and the seats of the three positive infected people were the same. Among the other infected people reciprocal.

In addition to the closed space of the cabin, there are also people infected by 3-5 meters apart because they have walked the same exit channel with positive infected people. They were infected less than 1 minute before and after.

Zeng Diandian analyzed that viruses were transmitted through air solution and long airplane time, unconventional masks, and failure for more than 4 hours, etc., all the causes of accelerated virus transmission.

In addition, from the perspective of the onset of positive infections, it is mainly the main infection of the upper respiratory tract, which is easier to copy and detoxify in large quantities. The incubation period is short. "BA.2.76 virus has a high load, and can spread a generation within 2 days."

Make a mask for 4 hours to replace

Keep your social distance as much as possible for more than 2 meters

According to the characteristics of the BA.2.76 mutation strain, what are the main points of attention? According to the recovery of this input epidemic, Zeng Dianxian gave important suggestions:

1. Make a mask for 4 hours to replace. He explained that the passengers on the plane were waiting to the airport, taking a plane, and landing. The time was over 4 hours, and the mask was not replaced. In an environment with a high virus load, the masks wearing the mask were basically invalidable. It's right. Therefore, when taking a plane and motorcycle, it is recommended to wear a mask above the medical surgical level to ensure that it is safe to be replaced for 4 hours.

2. Children should choose the right mask. Among the positive infections, children wearing N95 masks, but still infected. It is speculated that the face of the child is smaller. After wearing the N95 mask, it does not fit the face shape, which is not closed enough. Children should choose a mask that meets the requirements, and check whether it is closed after wearing.

3. It is not enough to maintain a social distance of 1 meter. Try to keep it more than 2 meters. Due to the very strong infectious power of this variable plant, it is recommended to extend the social distance to ensure safety.

4. Try not to go to a closed place for the crowd. For example, in a similar epidemic, a case of infection with the elevator who takes the elevator when a positive infection is also infected. This shows that the risk of being infected in a closed space is very high.

5. Do your hand hygiene. In addition to the dissemination of the respiratory tract, the virus may also be spread through contact, so keep his hands frequently.

13 rows can be transmitted in 13 rows on the front and rear of the plane

Suggestion: Reduce cross -provincial travel

Most of the epidemic infected in this epidemic is infected in the cabin, and the farthest is 13 rows. Jiang Xiangao, Jiang Xiangao, deputy leader of the expert group of the new crown pneumonia medical treatment of Wenzhou City, analyzed the long analysis of the flight time. During the period, the mask was taken off or wearing a mask was not standardized; the virus was transmitted by gas solidaries, which were all possible factor that caused multiple people infected.

This shows that the virus in the closed space is more contagious. Therefore, taking planes and trains, the chance of being infected is relatively high after encountering a positive infection.

Experts suggested that the recent reduction of inter -provincial travel without going to high -risk areas. If it is from other places (back) Wen, be sure to open the "Wenzhou epidemic prevention code" pre -report in advance, take the initiative to perform nucleic acid testing after arriving in Wenzhou, and cooperate with the community to implement health management measures.

Most of the asymptomatic infected

Suggestion: vaccine prevention

The effect is obvious, the vaccine is vaccinated throughout the process

Jiang Xiangao introduced that the positive infections that have been discovered in the epidemic have been treated in designated hospitals. From the perspective of symptoms, there are more than 80%of the asymptomatic infected, and all the rest are mild.

It is understood that the average age of infected people is 31 years old. Except for 1 child, all the rest have been vaccinated, and most of them have completed the whole process. Experts analyze that the age is light plus the vaccination of the whole process, so most of them are asymptomatic or mild after infection.

In this case, completing the full vaccination and strengthening needles can effectively prevent severe illnesses and death. Jiang Xiangao reminded that Omikon's mutant strains are very contagious. Ordinary citizens, especially elderly people who do not have contraindications, must vaccinate the vaccine as soon as possible and complete the inoculation of enhanced needles in accordance with the prescribed interval.
