Winter and spring are the high season of respiratory infectious diseases such as H7N9. Shu Yuelong, deputy director of the Institute of Virology of China CDC and director of the National Influenza Center, said that since the winter of last year, due to various factors such as climate, the global animal bird flu epidemic has been on the rise, affecting nearly 40 countries and regions such as Asia, Europe and the Middle East. The epidemic situation of H7N9 in China has the characteristics of increasing cases, wide distribution area and high distribution degree. Most cases are distributed in the Yangtze River Delta and the Pearl River Delta. However, the overall characteristics of the epidemic situation have not changed, and contact with infected poultry or live poultry market is an important risk factor for human infection. Existing evidence shows that it is impossible for the virus to continue to spread from person to person.
Ni Daxin, deputy director of the Emergency Center of China CDC, introduced that the National Health and Family Planning Commission further studied and deployed epidemic prevention and control work, strengthened territorial responsibility, played the role of joint prevention and control work mechanism, promoted the implementation of source control measures, and required areas where positive cases and external environmental viruses were detected to close the live poultry market. After taking this measure in some cities and regions in Zhejiang, Jiangsu, Anhui, Guangdong and other provinces, the number of new cases decreased significantly or no new cases appeared; Strengthen the control of live poultry transportation in different places, strengthen preventive measures such as quarantine, cleaning and disinfection of live poultry, and actively promote the research and implementation of long-term measures such as prohibiting live poultry trading, promoting the transformation and upgrading of poultry industry, and implementing the circulation and listing of chilled poultry products.
How to prevent and treat it? It is understood that while strengthening epidemic monitoring and risk assessment, the National Health and Family Planning Commission will strengthen patient treatment, improve the diagnosis and treatment plan, increase the training of grassroots first-line medical personnel, strengthen case screening and early diagnosis, and strive to achieve early detection, early reporting, early diagnosis and early treatment, and strive to reduce the occurrence of severe cases; We should allocate medical resources, ensure the supply of medical facilities, medicines and protective articles, strengthen severe treatment and minimize mortality.
Experts suggest that the public should avoid contact with live birds, let alone dead birds, especially in winter and spring and epidemic areas. Wash your hands as soon as possible if you touch them; In addition, efforts should be made to change the living habits of buying and consuming live poultry, and to buy chilled poultry, chilled poultry and their products with quarantine certificates. Raw poultry meat and eggs must be thoroughly cooked, and hands should be thoroughly washed after processing raw poultry meat and eggs; In the process of food processing, raw and cooked foods should be separated; If you have fever and respiratory symptoms, you should wear a mask and see a doctor as soon as possible.
The latest prediction of the disease From the current situation, the overall mortality rate of H7N9 avian influenza patients is about 40%. Chen Zhihai, chief physician of beijing ditan hospital Infection Center, said that the existing antiviral drugs, such as oral oseltamivir and intravenous palamivir, can effectively inhibit influenza virus. However, the sooner these drugs are used, the better the effect will be. The main reason for the high mortality of patients is that they missed the best opportunity for treatment. Therefore, patients with fever should see a doctor and use antiviral drugs as soon as possible.
Recently, the National Health and Family Planning Commission, together with agriculture, industry and commerce, food and drug supervision and other departments, formed a joint supervision team twice to supervise the prevention and control work in key epidemic provinces and guide local governments to strengthen the implementation of prevention and control measures. According to statistics, from February 6 to 12, 69 cases of human infection with H7N9 avian influenza were reported nationwide, and 8 people died. 12- 14, the national epidemic situation showed a downward trend, with 3 cases, 1 and 4 cases reported respectively.
Experts predict that there will still be sporadic cases of H7N9 in Chinese mainland in the near future. Song Shuli, spokesperson of the National Health and Family Planning Commission, said that the epidemic information and the progress of prevention and control work will be announced in accordance with the law, and public concerns will be responded in a timely manner. At present, the epidemic situation is temporarily adjusted from monthly release to weekly release. ?
