According to the Shenzhen Health Commission on February 8, the genome sequencing of the newly confirmed COVID-19 case in Shenzhen on January 31 was confirmed to be the Omicron variant (BA.1 evolutionary branch).In addition, the omicron epidemic in Shenzhen, Guangdong province has affected nine cities in Guangdong, Guangxi and Hunan provinces.On the same day, at a press conference under the Joint prevention and control mechanism of The State Council, He Qinghua, a first-level inspector with the NHC disease Control and Prevention Bureau, said that the virus sequence of seven asymptomatic cases reported in Heihe, Heilongjiang province, showed the omicron mutant strain.According to a health Times reporter, since 2022, about 7 local confirmed COVID-19 cases in China have been infected with the omicron variant virus.He Qinghua, first-level inspector of the National Health Commission for Disease Control and Prevention, has reported many local cases of Omicron since the first local case of omicron variant strain (ba.1 evolutionary branch, and the current outbreak in Tianjin also spilled to Anyang, Henan province) appeared in Tianjin in early January.The first case of an omicron variant (ba.1 evolutionary branch) was detected in Wuxi, Jiangsu Province on January 10. The patient arrived in Shanghai from Australia on January 5.On January 14, zhuhai Municipal People’s Government announced at a press conference that on the morning of January 13, a local case was reported in Tanzhou Town, Zhongshan City, which was preliminatively identified as Omicron virus after genetic sequencing.On January 17, a new local case was confirmed in Beijing, which was related to the sending and receiving of international mail. The specific mutation site of omicron mutant strain was detected in the environmental sample of this international mail.On January 26, hangzhou reported a new confirmed case of the virus infected with omicron variant (BA.1 evolutionary branch).Worldwide, the omicron original strain still accounts for the vast majority of new cases worldwide.As of Jan. 31, it was 96.4%, according to WHO.But genetic sequencing suggests that the subvariant ba.2 is rapidly gaining ground and is soon expected to dominate new cases in India, Nepal, the Philippines, Qatar and other countries.On 6 February local time, Dorit Nitzan, WHO regional emergencies Director, told the Jerusalem Post that the Ormica strain ba.2 is expected to become the new dominant strain globally.Many countries in Europe are relaxing their quarantine measures. Who warns that the number of omicron infections in multiple countries has not yet peaked. In the context of novel coronavirus activity, these countries should lift restrictions in a steady, slow and gradual manner.On February 8, the German federal health minister lauterbach with German federal CDC Robert Koch institute held a joint press conference, weiler lauterbach worry about the outbreak of the deterioration of the situation, and said, now the largest number of infections of the new champions, which makes “from the Angle of epidemiology, in such a large number of infection is likely to happen in new mutations.”(Qiao Jingfang)
