As we all know, Omikon BA.5.2 has more evolutionary branches, faster and more concealed. What are the specific performances of these characteristics? On September 2nd, Wang Xiaojun, the director of the Emergency Control and Prevention and Control Center of the Autonomous Region's Disease Prevention and Control Center, answered.

Compared with previous poison strains, Omikon BA.5.2 evolved branches present 3 characteristics:

The first is more contagious and faster transmission.

According to relevant research reports, the basic regeneration of the strains is 18.6, which is 5.6 times the original strains, 3.65 times of Delta, and 1.39 times of Omikon BA.2. In layman's speaking, the basic regeneration is 18.6 means that 1 infected person can be transmitted to 18 people average.

Second, the virus is more hidden.

The asymptomatic infection discovered by the epidemic accounts for relatively high. A small number of infected people have a positive time lags in the time of the onset of the onset of the disease. Symptoms such as fever, cough, and sore throat have occurred. However, the test results of nucleic acid tests are still negative, resulting in early discovery and early control of cases, which can easily cause diffusion and spread.

Third, the virus spacing is shorter.

The algebraic spacing refers to the interval between the onset date of the primary case and the onset dates caused by its infection. The shorter the spacing of the generation, the faster the effective transmission of the virus, the faster the spread of the population in the crowd. The an average of 2-3 days on average of Omikon BA.5.2 evolutionary branch, and some cases can be passed on to 1st generation.

In view of the dissemination of Omikon BA.5.2 evolutionary branches, Wang Xiaojun reminds the public that during the epidemic period, please actively participate in nucleic acid testing in accordance with the requirements of the territorial epidemic prevention and control work headquarters, and actively cooperate with the various prevention and control measures adopted by the local government. In particular, when implementing social prevention and control in partitioned dynamics, it is necessary to strictly implement the premium requirements of high -risk zones "without leaving the house", and the "people who do not go out of the zone to peak the peaks".

During the epidemic, residents should do personal protection in accordance with the "Code of Citizen Citizen's Basic Conduct", continue to maintain good health habits such as masks, hard -working hands, and less gathering, and do a good job of self -health monitoring. Suspected symptoms report to the local villages (communities) as soon as possible, and the village (community) will help contact the medical treatment in time.

8. Do a good job of cleaning and disinfection. Keep the room tidy everyday. Cooking utensils and countertops that deal with imported frozen foods, the items and catering utensils used by patients and visitors, should be cleaned and disinfected in time. When collecting express delivery, wipe or spray the express packaging with 75%alcohol or chlorine -containing disinfection agent, discard the outer packaging in time after sealing, and do it with hand hygiene. Before the use of air conditioners, cleaning and disinfection of the air -conditioned wall -mounted filter, the surface of the evaporator, and the inlet air outlet.

9. Keep the toilet hygiene. Cover the toilet cover before the toilet flushing, often open the window or open the exhaust fan to keep the water sealing water. Cleanly clean the sanitary ware and ground in the toilet. When there are dirty or moldy points on the surface, it is necessary to clean and disinfect in time.

Strengthen physical exercise, adhere to the rules of schedules, ensure sufficient sleep, and maintain a healthy mentality; healthy diet, quit smoking and alcohol; do daily health monitoring, fever, dry cough, fatigue, sore throat and other symptoms, seek medical treatment in time.

11. Nucleic acid detection. In accordance with the requirements, do a good job in the test of nucleic acid prevention and control in the normalized epidemic and the disposal of the local epidemic.

12. vaccination. In response to the country's new crown virus vaccination policy, the people who have no contraindications for inoculation of taboos in the age of 3 should vaccinate the vaccine to achieve "depletion" and protect personal health.
