Seeing these cases, you know how important wearing a mask

Today (27), the Chongqing Municipal Government News Office held a press conference on the 119th Chongqing New Crown Pneumonia Epidemic Prevention and Control Work. Luo Fei, chief physician of the Municipal Centers for Disease Control and Prevention, introduced the virus characteristics of Chongqing's this round of virus.

Luo Fei introduced the relevant situation Zou Le Photo

There are many epidemics in Chongqing

All Omikon variants

"At present, Omikon mutant strains have become the advantages of overseas input and local epidemics. Studies have found that the average incubation period of Omiko's mutant strain is shortened, the transmission capacity is stronger, the transmission speed is faster, and the transmission process is hidden."

Luo Fei introduced that at present, there are many epidemic conditions in Chongqing, all of which are Omicong's mutant strains. In the early stage, BA.5.1.3 was mainly BA.2.76. Shapingba 8.16 epidemic and Kowloon Po -22 epidemic chain was caused by BA.2.76.

Regarding the characteristics of Omikon's mutant strain, Luo Fei gave an example:

On August 24th, Beibei District found two infected people in the screening of nucleic acids in the central city, and immediately tone chasing the sun to investigate their close -up and sub -dense risks to test nucleic acid testing. But in fact, the five people also participated in the nucleic acid screening on the 24th, and the result was negative. Because the virus has a growth process in the human body, if the virus load in the early stage of infection is lower than the detection threshold, it is difficult to detect positive. On the one hand, the screening of nucleic acid screening is very important. On the other hand, it is difficult to detect all positives through a screening due to strong hidden virus.

Therefore, for the characteristics of Omikon's mutant strains, the "New Coronatte Pneumonic Pneumonia Prevention Plan (Ninth Edition)" has clarified the requirements of multi -frequency nucleic acid detection on densely connected, sub -dense connections, and history of risk areas.近期重庆多个临时管控区就进行了多轮核酸检测，比如沙坪坝区临时管控区有些市民已接受了核酸检测，但可能因为病毒隐匿性强，一次、两次甚至三次、四次都无法完全将Its detection has led to a new positive infection report from some communities and buildings, and multiple rounds of testing may be required, and everyone is requested to give understanding and support.

Regarding the characteristics of strong communication ability, Luo Fei for example:

Some time ago, a person returned from the city outside the city to relax the vigilance after the first nucleic acid testing for negative, and frequently dinner with family members and friends, and did not take any personal protective measures at entertainment venues such as KTV. On the third day, when the test results of the nucleic acid test of the personnel were positive, about 10 family members and friends had been infected, causing a clustered epidemic in the family, and subsequently caused the epidemic in many districts and counties in Chongqing.

Luo Fei emphasized that citizen friends who must carry out 2 days of nucleic acid testing in accordance with health management measures must be based on the attitude of being responsible for themselves, being responsible to the family, and responsible for society. Do not go out. You must be reported to the community to agree, and do personal protection. During the period, you do not gather dinner, do not take public transportation, and do not go to a closed public place.

Wearing a mask is important

Just look at these cases and you know

"It is important to wear a mask. Because the new crown virus is mainly through the respiratory tract and close contact with the respiratory tract, wearing a mask is very effective in preventing and controlling respiratory infectious diseases."

Luo Fei gave an example again at the press conference, emphasizing the importance of wearing a mask:

On one occasion, I found that a infected person had a wide range of activities. He took a bus many times and stayed in a chess room for a short time. We are very worried that these social activities will cause a large epidemic dissemination, so quickly act, edge and tone investigation, border management control detection, and quickly find all close contacts and close contacts. A few days later, several positives were discovered among these contactors, but they were all activists of chess and cards, and no positives were found among those who took the bus. We believe that the reason is that although the chess and card rooms and buses are closed, the relevant personnel in the chess room did not wear a mask, and the relevant personnel in the buses were regulated to wear masks.

Recently, there is another infected person who goes to a park without wearing a mask. Most of the personnel who are active at this place have not worn a mask. Although this is an outdoor open place, it still leads to more than 30 infected people in the future. Essence

Earlier, there was also a infected person who had repeatedly traveled to and from North Railway Station, train west station and other dense transportation stations. There were many close contacts, but they were not infected in the end. The flow was found that the infected person had been wearing a mask, including walking or staying in public places.

"The above cases let us realize that standardizing wearing masks can indeed effectively reduce the risk of infection and block the spread of virus. I have to say that it is more popular -as long as the mask is worn well, the virus is difficult to do." Luo Fei is strong. Call for citizens friends to wear masks and make personal protection when they are intensive places, public transportation and closed space, and do a good job of personal protection.
