China News Agency, Beijing, December 20 (Ma Shuaisha) Lei Zhenglong, deputy director of the National Health Commission for Disease Control and First Inspector of China’s National Health Commission, said in Beijing on the 20th that recently, China’s Tianjin, Guangzhou, Changsha and other places have reported that Imported cases of Omi Keron mutant strains, local cases caused by imported cases of Omi Keron mutant strains have been reported in individual regions, and the existing infection prevention and control measures in medical institutions in China are still effective for the Omi Keron mutant strains.

  On the same day, the Joint Prevention and Control Mechanism of the State Council of China held a press conference.

Lei Zhenglong pointed out at the meeting that recently, many countries and regions around the world have found cases of Omi Keron variants. China’s Tianjin, Guangzhou, Changsha and other places have reported imported cases of Omi Keron variants, and some regions have reported Omi Keron variants. The local cases caused by the imported cases of the Mikeron mutant, "this suggests that we cannot relax our prevention of the Omi Keron mutant."

  To this end, he pointed out that the National Health Commission will focus on deploying and strengthening the prevention and control of Omi Keron mutant strains from four aspects:

  The first is to insist on "personal defense" and strengthen the input of foreign defense at ports.

For personnel in high-risk positions at ports, the prevention and control requirements such as standardized protection, closed-loop management, and high-frequency nucleic acid testing shall be implemented.

Increase the sampling inspection rate of imported goods from high-risk countries, and do a good job of preventive disinfection of the surface of goods;

  The second is to strengthen the management of centralized isolation sites to strictly prevent cross-infection.

Strictly release the standards for quarantined personnel, and the quarantine can be lifted only if the three samples of people, objects, and environment are negative.

For those who are found to be positive for nucleic acid testing in the centralized isolation site, immediately review the flow of investigations, recalculate and extend the isolation time for risk personnel;

  The third is to strengthen monitoring and early warning.

Pay close attention to the epidemic trend of Omi Keron mutant strains in the world and neighboring countries of China, strengthen the monitoring of new mutant strains, and carry out virus gene sequence determination on all qualified imported cases, inbound articles and positive samples from the relevant environment;

  The fourth is to strengthen emergency response to the epidemic.

The emergency command system was activated immediately after the outbreak.

  "China's existing medical institution infection prevention and control measures are still effective against Omi Keron mutant strains. In the medical institution infection prevention and control work, the existing prevention and control measures must still be implemented." Lei Zhenglong said.

  Lei Zhenglong said that the current national epidemic situation is generally stable.

The associated epidemic in Manzhouli, Inner Mongolia, has been basically controlled.

The development of the epidemic situation in Shaoxing, Zhejiang has slowed down, and the risk of epidemic spillover has been reduced.

The epidemic situation in Ningbo, Hangzhou, Shanghai, Jiangsu, Anhui and other places in Zhejiang Province has basically been brought under control.

The Xi'an-Dongguan related epidemic situation is still developing, and the risk of continued transmission between the two places is relatively high. Recently, sporadic cases of spillage have been discovered, and the investigation of risk personnel is being carried out.

The local cases reported in Guangzhou caused by imported cases of overseas Omi Keron mutant strains have been promptly taken to investigate risk personnel, and the risk of recurrence and transmission is low.

The cases reported by Xiamen and Chengdu in closed-loop management personnel have a low risk of community transmission.

  Mi Feng, spokesperson for the National Health Commission of China and deputy director of the Propaganda Department, said at the press conference that at present, 89 countries and regions around the world have reported Omi Keron variants, and the epidemic situation in some neighboring countries in China is increasing rapidly. The input pressure continues to increase.

The most important thing to prevent the imported epidemic from abroad is the port. The key is to implement various prevention and control measures, strengthen the control of the source of the epidemic and the safe and orderly flow of personnel.

  New Year's Day and the Spring Festival approaching, Mi Feng said that we must always tighten the string of epidemic prevention and control, strengthen duty, implement the "four morning" requirements, and strengthen closed-loop management. Once an epidemic occurs, deal with it quickly, resolutely, and decisively, and stop it as soon as possible. Spread, to ensure that the holidays are not relaxed, the closed loop can be closed, prevention and control are in place, and the measures are temperature.

It is necessary to fulfill the responsibility of personal protection, strengthen self-protection, and actively vaccinate the new coronavirus vaccine.
