Le Health | About Ami Kerong, the latest answer from the National Health Commission is coming!

Recently, many places have reported the discovery of infection cases of the Aomi Kerong variant, which has aroused widespread concern. In response to the Aomi Kerong variant, experts from the Chinese Center for Disease Control and Prevention organized by the National Health Commission made the latest answers to relevant questions.

1. The discovery and prevalence of the Aomi Kerong variant

On 9 November 2021, a variant of the new coronavirus was detected for the first time in South Africa from a sample of cases. On 26 November, the World Health Organization named it the Omicron variant. According to the global covid-19 database GISAID, as of January 17, 2022, 118 countries have submitted 374314 genome sequences for the Omikejung virus. At present, the Omiljung variant has become the dominant popular strain in the world.

The Omikejong variant was first imported into Hong Kong on November 27, 2021, and was first imported into mainland China on December 9, 2021.

2. The spread of the Omikejong mutant strain

Multinational epidemiological data suggest that the transmission capacity of the Omikejong variant is enhanced compared with other variants. The World Health Organization's 23 December 2021 briefing on Omikeron showed a household renewal rate of 15.8 percent, up from 10.3 percent in Delta. According to the UK Health Security Agency, 90% of COVID-19 cases in London and 76% of COVID-19 cases in England were infected with the Aumecreon variant from 19 to 20 December 2021. According to the US Centers for Disease Control and Prevention website, in the week from December 26, 2021 to January 1, 2022, 95.4% of the new crown pneumonia cases in the United States were infected by the Olmikron variant.

3. The effect of existing vaccines on the prevention of infection of the Aomi Kerong variant

The results of the existing studies show that the Olmi kerong variant does not completely immunize to escape from the existing vaccine; the existing vaccine still has a certain protective effect on the Aomi kerong variant, but its ability to prevent infection has declined; it has not been found that the Olmi kerong variant causes an increase in the rate of severe illness and mortality, and for the Aomi kerong variant, the existing vaccine is still effective in preventing severe illness and death.

4. Effect of the Omikeron variant strain on existing nucleic acid detection reagents

The genomic analysis of the Omikerong mutant strain showed that its mutation site was not located in the primer and probe target area of the nucleic acid detection reagent published in the eighth edition of the "Novel Coronavirus Pneumonia Prevention and Control Plan" in mainland China, which did not affect the sensitivity and specificity of mainstream nucleic acid detection reagents in mainland China.

5. Measures taken by relevant countries and regions

In view of the rapid global epidemic trend of the Omikejunn variant, the United States, the United Kingdom, Russia and the European Union have recently recommended that people strengthen daily hygiene protection (hand washing, wearing masks and safe social distancing), and health departments should strengthen disease surveillance, vaccination, especially for frontline health workers to inject COVID-19 vaccines.

6. The mainland's response measures

The mainland's general strategy of "external defense input, internal defense rebound" and "dynamic clearance" general policy are still valid for the Aumechjong variant. The Chinese Center for Disease Control and Prevention has established a specific nucleic acid detection method for the Omiljunn variant, and continues to carry out viral genomic surveillance for possible imported cases and associated indigenous cases, which is conducive to the timely detection of Possible imported or associated native Omilon variants.

7. Recommendations of the World Health Organization on the Response to the Opichron Variant

The World Health Organization recommends that countries strengthen surveillance, reporting and research on COVID-19 and take effective public health measures to interrupt the spread of the virus. Individuals are advised to stay at least 1 metre apart in public places, wear a mask, open windows for ventilation, keep their hands clean, cough or sneeze on elbows or tissues, vaccinate, etc., and avoid going to poorly ventilated or crowded places. Currently, all variant strains can cause severe illness or death. Therefore, preventing the spread of the virus is always key, and the NEW Crown Virus vaccine remains effective in reducing severe illness and death.

8. In the face of the Aomi Kerong mutant strain, the public's precautions in daily life and work

(1) Wearing a mask is still an effective way to block the spread of the virus, and the same applies to the Omikejung variant. Even after completing the full vaccination and vaccination of the booster, it is also necessary to wear a mask in indoor public places, public transportation and other places. In addition, wash your hands frequently and ventilate indoors.

(2) Do a good job of personal health monitoring. When there are suspected symptoms of new crown pneumonia, such as fever, cough, shortness of breath and other symptoms, timely monitor body temperature and take the initiative to seek medical treatment.

(3) Reduce non-essential travel. Try not to travel to high-risk countries or areas, and if necessary, strengthen personal protection during travel to reduce the risk of contracting the Aumecreon variant. Pay close attention to the domestic local cluster epidemic situation, do not go to the county (city, district, flag) where the epidemic is not necessary, and the residents of the place where the epidemic is not necessary do not leave their place of residence.

Beijing: Minimize the purchase of overseas goods, and pay attention to these when receiving overseas mail

On January 17, at the 267th press conference on the prevention and control of the new coronavirus pneumonia epidemic in Beijing, Pang Xinghuo, deputy director of the Municipal Center for Disease Control and Prevention and a member of the national new coronavirus pneumonia expert group, said that many provinces (cities) in the mainland have also reported cases of transmission through cold chain or non-cold chain items, and recently many places in the mainland have also reported positive overseas mail and other items. The coronavirus can survive in low temperatures for a long time, and the risk of material transmission in winter increases. At present, the new crown pneumonia epidemic caused by the global Aomi Kerong variant strain is high, and the general public is reminded of the general public:

First, during the high incidence of the epidemic in foreign countries, minimize the purchase of overseas goods.

Second, if you receive mail or items from abroad, you should wear masks and disposable gloves correctly to reduce direct contact and communication.

The third is to pick up the package at a fixed location as much as possible to achieve contactless handover; if you need to sign in person, you should keep a distance of more than 1 meter from the courier.

Fourth, when disassembling parts, try to carry out outdoors, the outer packaging should not be taken home, and should be classified according to the domestic garbage; if it needs to be taken home, it can be used with chlorine-containing disinfectants or comprehensive disinfection of the internal and external packaging.

Fifth, after handling the mail, take off the gloves in time, replace the mask, carefully disinfect or wash the hands, and avoid touching the mouth, eyes, and nose with unclean hands.

According to the traceability results, once again remind the public friends, since January 11 with the city's reported confirmed case trajectory has intersected, please take the initiative to report to the community, units, hotels, etc., and cooperate with centralized isolation, home isolation, health monitoring, nucleic acid testing and other prevention and control measures.

At present, the city is still facing the double risk of importing the epidemic situation at home and abroad, and the situation of prevention and control is complex and severe. All units and individuals are invited to strengthen their awareness of prevention and control, pay close attention to the progress of the epidemic at home and abroad, and effectively implement the responsibilities of the four parties. Let us work together to build a security barrier in the capital.
