Deep Network Observation | Shenzhen first discovered BF.15 mutant strains, which is important to standardize wearing masks

On the afternoon of August 29, Shenzhen held an epidemic prevention and control press conference.

The Shenzhen Centers for Disease Control and Prevention has conducted a virus -based sequence comparison analysis of all cases since August 23. The results show that most cases of infected strains are BF.15 mutant strains (sub -branches of BA.5.2.1) It was the first discovery of Shenzhen in Shenzhen; the other cases were infected with the strains of BA.5.2, BA.5.2.1 and BA.2.2.

The above -mentioned cases of infection strains are highly the same as the sequence of some strains reported by overseas reports. It does not rule out the possibility of local infection caused by overseas inputs.

The positive cases of the Shenzhen epidemic in this round of epidemic are mainly hidden and transmitted Omikon BA.5 evolution branches. In addition, the current domestic and domestic epidemic is delayed, which has led Shenzhen to face the risk of rebounding and overseas epidemic in Shenzhen at the same time. The risk of inverted irrigation and the three challenges of the input risks in domestic and high -risk areas will be the period with the city's most risks, the highest risk, and the most severe situation in the future.

In this regard, Shenzhen has recently focused on three aspects of response: due to the time adjustment of prevention and control strategies, strengthening "people, things, and environment", the same prevention and control, and normalization prevention and control.

Omikon is not playing in trouble. Here we should remind citizens to take public transport and enter community communities, industrial parks, commercial office buildings and other public places to standardize masks.

Omikon has strong hidden hiddenness, fast transmission speed, highly contagious, non -standard masks, or failure to replace masks in time, which may cause virus breakthrough protection. It is recommended to replace the mask once every 4 hours. Citizens are requested to continue to strengthen their awareness of prevention, maintain good sanitation habits such as "diligently washing hands, one -meter line, constant ventilation, and less gathering", and strict implementation of nucleic acid results must be checked, body temperature must be tested, and the site code must be swept.
