(Fighting against New Coronary Pneumonia) The ability of all parts of China to respond to the epidemic has been further improved
China News Agency, Beijing, July 21. Comprehensive news: China's National Health and Medical Commission announced on the 21st that there were 200 new confirmed cases in mainland China on the 20th, of which 52 were imported from abroad and 148 were local.
There were 743 new asymptomatic infections, including 65 imported cases and 678 local cases.
No new deaths were reported.
As of 24:00 on the 20th, there are 1,615 confirmed cases in mainland China, a total of 5,226 deaths, and a total of 228,180 confirmed cases.
There are currently 510 confirmed cases imported from abroad, with a total of 20,213 confirmed cases and no deaths.
The existing measures to further improve the ability of all parts of China to respond to the epidemic are still valid for BA.4 and BA.5
On the 20th, there were 826 new local infections (confirmed + asymptomatic) in mainland China, exceeding 800 for two consecutive days.
Among them, 148 cases were confirmed locally, from 8 provinces: 52 cases in Guangxi, 49 cases in Gansu, 18 cases in Guangdong, 16 cases in Sichuan, and 4 provinces with new single-digit additions; 678 cases of local asymptomatic infections, distributed in 11 provinces: 314 cases in Gansu, 135 cases in Guangxi, 77 cases in Anhui, 76 cases in Henan, and the other 7 provinces have new cases of less than 30 cases each.
China's National Health Commission said on the 21st that since July, the epidemic situation in mainland China has generally been in a low-level fluctuation state. Recently, the epidemic situation in a few areas has rebounded, showing a trend of scattered and frequent occurrences in many places.
In the past week, the local epidemic in mainland China has affected 78 cities in 21 provinces. Among them, Lanzhou in Gansu, Beihai in Guangxi, and Zhumadian in Henan are still in the advanced stage, and the risk of social transmission is relatively high.
On the whole, all localities can effectively control the epidemic in a relatively short period of time after the outbreak, and the response and disposal capacity and efficiency have been further improved.
Recently, the Omicron BA.5 variant has appeared in many places in China, which has attracted attention.
Dong Xiaoping, chief expert of virology at the Chinese Center for Disease Control and Prevention, said on the 21st that the transmissibility of BA.4 and BA.5 subclades has slightly increased compared with other Omicron variants, and the pathogenicity is generally similar to that of other Omicron variants. strains are similar.
However, the epidemiological mathematical model study shows that the infection rate and mortality caused by BA.4 and BA.5 subclades will increase.
Nonetheless, China's existing prevention and control measures are still effective.
Dong Xiaoping believes that multiple variants of the new coronavirus have appeared in just two and a half years, forming multiple epidemic peaks.
Most scholars believe that the mutation of the new coronavirus will exist for a long time, and the Omicron mutant should not be the last mutant.
For the monitoring of new mutants, the influence of their transmission, pathogenicity and immune escape will be the long-term focus of the industry.
In Lanzhou and Beihai, the current round of infections exceeded 1,000 cases, and 21 cases from Beihai spilled positive but did not spread
On the 20th, Gansu Province added 49 local confirmed cases and 314 asymptomatic infections, involving multiple cities and prefectures, including 41 confirmed cases and 191 asymptomatic infections in Lanzhou.
As of 24:00 on the 20th, Gansu Province has reported a total of 1,655 local infections (325 confirmed cases and 1,330 asymptomatic cases), including 1,202 cases in Lanzhou.
Lanzhou City announced on the 21st that a round of nucleic acid screening in key areas that the city recently concluded detected 121 positive cases, including 35 social cases, indicating that the epidemic still has a greater risk of social transmission.
The results of the virus gene sequencing analysis showed once again that the virus in Lanzhou was the Omicron variant BA.2.38, which was characterized by a wide range of sites, a short intergenerational transmission interval, and a large number of epidemic-related places. Control work brings great difficulties and challenges.
On the 20th, Guangxi added 52 local confirmed cases and 135 asymptomatic infections. Except for 4 asymptomatic infections reported in Fangchenggang City, the rest were all in Beihai City.
As of 24:00 on the 20th, Beihai City has 1,132 local infections, becoming another city in mainland China with more than 1,000 local infections after Lanzhou.
Beihai City issued a notice on the 21st. In order to further identify potential risk personnel, the city has carried out nucleic acid testing for all employees for three consecutive days starting on the 21st.
In order to limit unnecessary travel to the greatest extent, from 7:00 that day, temporary traffic control will be implemented on some roads in the main urban area of Beihai City.
According to the official introduction of Guangxi, the number of positive social cases in Beihai City is continuing to decrease, and the development trend of the epidemic is gradually slowing down.
As of 15:00 on the 20th, a total of 21 positive cases in Beihai had spilled over to 8 counties (districts) in 5 districts and cities, all of which were found in key control personnel and did not spread to the society.
At present, the epidemic situation in Guangxi is generally stable, and the order of production and life is normal.
Shanghai adds 12 more high-risk areas, Shenzhen adds 22 new local infections
On the 20th, Shanghai added 3 local confirmed cases and 14 asymptomatic infections, of which 4 asymptomatic infections were found in social screening.
The Shanghai Leading Group Office for Epidemic Prevention and Control announced on the 21st that it adjusted the epidemic risk levels in some areas of the city, adding 4 high-risk areas and 8 medium-risk areas.
On the 20th, Guangdong Province added 17 local confirmed cases and 6 asymptomatic infections. Except for one asymptomatic infection reported in Zhuhai, the rest were all from Shenzhen (there was another local asymptomatic infection in Guangzhou who was transferred to a confirmed case).
According to a report from Shenzhen City, among the 22 newly infected people in the city on the 20th, some still came from the social side and those who took the initiative to seek medical treatment.
The above-mentioned case trajectories involve Nanshan District, Futian District, Dapeng New District, Pingshan District and other places. Among them, 13 cases live in Nanshan District, and many places in Nanshan District have been adjusted to medium and high risk areas.
Anhui Province added 7 local confirmed cases and 65 asymptomatic infections on the 20th, mainly from Huaiyuan County (7+65) in Bengbu City.
From July 15th to 20th, a total of more than 400 local infections were reported in Huaiyuan County in this round of the epidemic.
According to reports, as of the afternoon of the 21st, including Huaiyuan County, Bengbu City has had zero new social infections for 3 consecutive days, and the city's epidemic situation has continued to stabilize and improve.
Hongya County, Sichuan suspends public transportation in the county, Zhumadian, Henan has more than 500 cases of infection in this round

According to reports, newly infected people in Chengdu were found in close contacts who were quarantined and controlled, and the transmission chain was clear.
However, the virus in this outbreak is the Omicron variant BG.2, which spreads faster and is more difficult to prevent and control than the virus strains in previous local outbreaks in the city.
To this end, Chengdu has comprehensively strengthened the city's social epidemic prevention and control measures.
On the 20th, Meishan City added 3 local confirmed cases and 24 asymptomatic infections, all in Hongya County.
