(Fighting against New Coronary Pneumonia) There are zero new cases in Beijing and Shanghai, and new cases in Nanjing and Si County, Anhui, related to the epidemic

  China News Agency, Beijing, June 28. Comprehensive news: The National Health and Health Commission of China reported on the 28th that 16 new confirmed cases were reported in mainland China on the 27th, including 15 imported cases and 1 local case (in Guangdong).

There were 84 new asymptomatic infections, including 63 imported cases and 21 local cases (6 cases in Anhui, 4 cases each in Tianjin, Liaoning, Guangdong, and 3 cases in Guangxi).

No new deaths were reported.

  As of 24:00 on the 27th, there were 487 confirmed cases in mainland China, a total of 5,226 deaths, and a total of 225,581 confirmed cases.

There are 304 confirmed cases imported from abroad, with a total of 19,320 confirmed cases and no deaths.

  The low-level fluctuation of the epidemic situation in mainland China has been found in Omicron variant BA.4 and BA.5

  China's National Health Commission said at the press conference of the State Council's joint prevention and control mechanism held on the 28th that the recent epidemic prevention and control in mainland China has achieved remarkable results, and the epidemic has generally fluctuated at a low level.

However, sporadic social infections continue to occur in individual areas, and the risk of community transmission still exists.

On the whole, the global epidemic is still developing, the new crown virus is constantly evolving, and the epidemic prevention and control situation in China is still grim.

  The Chinese Center for Disease Control and Prevention said at a press conference on the same day that some experts predict that the world may face a new wave of epidemics caused by the Omicron variant BA.4 or BA.5 this summer.

Since February this year, the main virus strain circulating in China has been the Omicron BA.2 subclade series, but since BA.4 and BA.5 were first detected in imported cases in May, the virus strain was imported abroad. There are signs of a gradual increase in cases.

Judging from the existing research results, the transmission ability and immune evasion ability of these two strains have been slightly enhanced, the difficulty of prevention and control will increase, and the pressure of China's foreign defense import will increase.

  At the press conference on the same day, the National Health and Medical Commission introduced the main differences between the newly released "New Coronavirus Pneumonia Prevention and Control Plan (Ninth Edition)" and the previous edition: the ninth edition will isolate and control close contacts and inbound personnel. The time has been adjusted from "14+7" (14 days of centralized isolation medical observation + 7 days of home health monitoring) to "7+3"; unified closure and control areas and delineation standards for medium and high risk areas, forming new risk area delineation and control scheme; encrypt the frequency of nucleic acid testing for high-risk occupational groups, etc.

  The National Health and Medical Commission emphasized that the ninth edition of the prevention and control plan is an optimization and adjustment of prevention and control measures.

  There are zero new cases in Beijing and Shanghai, and there are new cases in Nanjing and Si County, Anhui Province.

  There were no new local confirmed cases and local asymptomatic infections in Beijing and Shanghai on the 27th. For the first time since April 17, Beijing has achieved zero new local infections.

For the third time in the current round of the epidemic, Shanghai has achieved zero daily confirmed cases and asymptomatic infections.

  The Shanghai Epidemic Prevention and Control Leading Group Office announced on the 28th that from 0:00 on the 29th, Xuhui District and Hongkou District will be adjusted from medium-risk areas to low-risk areas.

So far, there are 10 medium-risk areas in Shanghai.

  On the 27th, Tianjin added 4 cases of local asymptomatic infections (reported on the 27th), ensuring closed-loop management staff for the entry service of international flights.

At present, the relevant departments of Tianjin and the district have implemented control over close and sub-close contact, comprehensively conducted environmental sampling and terminal disinfection of the sites involved, and organized related disposal work such as flow traceability and nucleic acid testing in an orderly manner.

  Nanjing City reported on the 28th that the city received a report from other provinces on the 27th that two people who tested positive for nucleic acid had a history of sojourn in Nanjing.

As of 17:00 on the 28th, Nanjing has identified 4 positive cases among relevant close contacts, all of whom are family members of nucleic acid-positive people in Si County, Anhui, including 2 confirmed cases and 2 asymptomatic infections.

From the 28th, the first residential area in Liuhe District, Nanjing has been adjusted to a medium-risk area.

  Local positive people appeared in many places in Anhui, there have been 9 cases of local infection in the past two days

  According to reports from Sixian County, 1 case of asymptomatic infection was found in the nucleic acid test of key groups of people in the county on the 26th, and 2 more positive people were found in the nucleic acid test of the close contacts of the infected person.

After the outbreak, the county immediately launched an emergency response, and implemented control measures throughout the county from 0:00 on the 27th. Various checkpoints were on duty 24 hours a day, and passenger transport on inter-provincial, city-county highways and urban and rural public transportation were suspended.

  The latest news from Hefei City said that on the 28th, another nucleic acid positive person was found in the nucleic acid screening of key populations in the Shushan District of the city.

This person arrived in Hefei by bus from outside the city on June 25.

  Shenzhen adds 5 more local infections, Dandong epidemic is still in the tailing stage

  Guangdong Province added 1 local confirmed case and 4 asymptomatic infections on the 27th, all in Shenzhen.
