The State Council Information Office held a regular briefing on the policy on the 28th to introduce the "Guiding Opinions on Promoting the High-quality Development of Disease Prevention and Control". Li Zhengmao, director of the Department of Planning, Finance and Regulations of the National Bureau of Disease Control and Prevention, said at the meeting that monitoring shows that the current new crown epidemic in China is at a low level, and the local epidemic strain is still eg5 variants, jnThe proportion of 1 variants is still relatively low, but it is also on the rise.
Q: Recently, the World Health Organization said that the new coronavirus jnThe 1 variant is spreading rapidly, and it was decided to replace JN1 is listed as a variant of concern. As of the 10th of this month, 7 cases of JN. have been detected in China1 case, how will the prevention and control of related diseases be done, and will the strain pose too much threat to China's public health?
Li Zhengmao said that recently, jn1 The proportion of variants has risen rapidly in the world and has become the main epidemic strain, and the epidemic situation in some countries has increased significantly. Monitoring shows that the current new crown epidemic in China is at a low level, and the local epidemic strain is still eg5 variants, jnThe proportion of 1 variants is still relatively low, but it is also on the rise. A total of JN1. There are 490 sequences of variants, of which 443 are imported cases, accounting for 90%, and 47 are local cases.
The available evidence suggests that jn1. The immune evasion and transmissibility of the variant were enhanced, but its pathogenicity was not enhanced, and previous infection and vaccination with vaccines containing XBB ingredients had the effect of immune cross-protection, and specific antiviral drugs were still effective.
Experts believe that this winter and next spring, China will continue to show a variety of respiratory diseases alternately or common epidemics. Influenced by foreign jn1. Influence of multiple factors such as the continuous importation of variants, the size and flow of people before and after the Spring Festival, jnThe 1 variant may develop into the dominant epidemic strain of the new coronavirus in China, which will contribute to the rise of the new crown epidemic, increase the risk of severe death of vulnerable groups such as the elderly and patients with underlying diseases, and may put some pressure on the rural medical service system with relatively weak treatment capacity. The National Bureau of Disease Control and Prevention must attach great importance to it, make careful arrangements, and make preparations in all aspects.
Li Zhengmao said that the National Bureau of Disease Control and Prevention will continue to do a good job in the prevention of new crown and multiple diseases, continue to pay attention to the dynamic changes of the international epidemic and epidemic strains, strengthen epidemic monitoring and early warning, and promote the vaccination of high-risk groups with severe disease such as the elderly and patients with chronic underlying diseases to receive new coronavirus vaccines containing XBB ingredients, so as to reduce the risk of severe disease and death after infection. At the same time, with a focus on rural areas, we should make good preparations for the response of medical resources, and strengthen the management of hierarchical and categorical treatment of infected persons.
Li Zhengmao reminded that the New Year's Day and the Spring Festival are approaching, and the Spring Festival is about to arrive, and the flow of people and gathering activities will increase, which may increase the risk of the spread of infectious diseases. It is recommended that everyone continue to maintain good hygiene habits such as frequent ventilation, frequent hand washing, and social distancing, and wear masks scientifically when taking public transportation or going to crowded placesThe elderly, patients with severe chronic underlying diseases, pregnant women, etc., should minimize going to crowded places;Patients with respiratory infections or those with related symptoms are advised to postpone travel and avoid going to crowded places.
