Winter and spring are high incidences of H7N9 and other respiratory infectious diseases. Shu Yuelong, deputy director of the China Center for Disease Control and Prevention and director of the National Influenza Center, said that since the beginning of winter last year, due to climate and other factors, the global bird flu epidemic has shown a high incidence, affecting nearly 40 in Asia, Europe, and the Middle East. Countries and regions. The incidence of H7N9 epidemic in China is characterized by an increase in cases, a wide distribution area, and a high degree of dissemination. Cases are mostly distributed in the Yangtze River Delta and Pearl River Delta regions. However, the overall characteristics of the epidemic have not changed. Exposure to infected poultry or exposure to live poultry markets is an important risk factor for human infection. The available evidence shows that the virus cannot yet cause continuous human-to-human transmission.
Ni Daxin, deputy director of the China Center for Disease Control and Prevention Center, introduced the National Health and Family Planning Commission to further study the layout of the epidemic prevention and control work, strengthen the responsibility of the region, play a role in the joint prevention and control work mechanism, promote the implementation of source control measures, and require positive detection of cases and external environmental viruses. The area closes the live poultry business market. In some cities and regions such as Zhejiang, Jiangsu, Anhui, and Guangdong provinces, the number of new cases has decreased significantly or no new cases have emerged; the control of live poultry transport to the outside world has been strengthened, and the live bird quarantine and cleaning, killing, etc. have been strengthened.

From the current situation, the overall mortality of H7N9 bird flu patients is about 40%. Chen Zhihai, chief physician of the Beijing Ditan Hospital Infection Center, said that existing antiviral drugs such as oral oseltamivir and intravenous infusion of palamivir can effectively inhibit the influenza virus. However, the sooner these drugs are used, the better the effect is, and the reason for the higher mortality rate of the patients is mainly the missed time for the best treatment. Therefore, patients with fever should seek treatment as soon as possible and use antiviral drugs as soon as possible.
It is understood that the National Health and Family Planning Commission will strengthen patient care, improve diagnosis and treatment plans, strengthen the training of first-line medical personnel at the grass-roots level, strengthen case screening and early diagnosis, and strive to realize early detection and early reporting. Early diagnosis, early treatment, and efforts to reduce the occurrence of severe cases; deployment of medical resources to ensure the supply of medical facilities, medicines and protective supplies, strengthen severe treatment, and minimize mortality.
Experts suggest that the public should avoid contact with live animals in their daily lives, not to contact sick and dead poultry, especially in areas where winter and spring seasons and epidemics occur. If contact is required, wash hands as soon as possible; in addition, efforts should be made to change the habits of purchasing and consuming live poultry, and to purchase chilled fresh poultry, chilled birds and their products with quarantine certificates.
