Xi'an discovered BA.5 mutant strains

Recently, a sudden epidemic in Xi'an had found a total of 18 infected people, and the source of infection was not clear.

On July 5th, Zhang Yi, director of the Prevention and Control Institute of the Shaanxi Provincial Disease Control and Prevention Center, disclosed in an interview with a reporter that after the sequence of the whole genome, it was determined to be the Ommaco BA.5 mutant strain. Essence

Chang'an Street Knowledge (WeChat ID: CapitalNews) noticed that my country found the first BA.5 infection in May in May.

On July 2nd, Xi'an found a positive infection in nucleic acid screening in key groups, and found five initial sieve -positive personnel in subsequent streaming investigations.

As of 24:00 on July 4, a total of 10 confirmed cases and 8 asymptomatic infections were found. Among them, the trajectory of multiplayer activities is related to Shaanxi Chaohui regeneration resource transaction distribution market (Great Frequency Regenerative Art Museum).

The research decision of the Xinguanye pneumonia epidemic prevention and control headquarters in Xi'an decided: From 12:00 on July 5th, the Baiyangzhai Village of Yanta District and other streets of Yanta District was adjusted to a high -risk zone. After the adjustment, the city has 5 high -risk areas, 3 mid -risk areas, and 4 low -risk areas.

According to the Western Network · Shaanxi Headline, since the epidemic in Xi'an this round, the Shaanxi Provincial Center for Disease Control and Prevention immediately conducted a whole genome sequence of the nucleic acid samples of the positive infected person.

Zhang Yi, director of the Prevention and Control Center of the Shaanxi Provincial Centers for Disease Control and Prevention, said that Omikon BA.5 mutant strains have stronger spreading capacity, faster transmission, and have stronger immune escape ability.

It is worth mentioning that at the end of May, the China Disease Control and Prevention Center released an English weekend that China has found the first infection of the first new crown virus Omircor's Omi Virus, which is infected by overseas.

The weekly report showed that the case departed from Uganda on April 25, and was transferred to Shanghai by Amsterdam and Seoul, South Korea. It was discharged on May 12. The results of the genome sequencing show that the patient infected the BA.5 mutant strain.

The gene sequence of BA.5 was first uploaded on March 15, 2022, and the nasopharyngeal and oral pharmaceutical swabs from a patient collected from South Africa on February 25.

In addition, on June 29, the World Health Organization (WHO) stated in the latest global new crown epidemic weekend that global new crown cases have increased by 18%in the past week, reaching the highest level since April. The infection caused by the strong Omikon BA.4 and BA.5 mutations.

As of June 19, the global new coronary virus gene sequencing samples obtained by the WHO show that the addition of BA.4 and BA.5 mutations has accounted for 55%of all samples. Poison.

The WHO said that the proportion of BA.4 and BA.5 mutations is still rising. The rise of the two is related to its mutation that enhances its infectivity. Early signs showed that these mutations increased the immune escape ability of the strains, which means that people who have been infected are more likely to be infected. People who have vaccinated the new crown vaccine are more likely to have breakthrough infections.
