Development Trend of Influenza A H1N1 influenza
By the end of October this year, China’s mainland had reported confirmed cases of Influenza A H1N1 influenza 4.6 thousand cases of the past half year, the flu epidemic in our country as well as the rest of the world spread rapidly. With the arrival of autumn and winter in the northern hemisphere, North America, Europe, Asia and other regions of the influenza A H1N1 flu has shown signs of rapid upward trend.
Chinese Ministry of Health deputy director of the Office of Emergency Liang years pointed out that the autumn season, the temperatures plunged, it makes the immune system to reduce airway drying, an increase in indoor activities, indoor spaces and poor ventilation conditions, factors that increased the risk of influenza infection.
Expert analysis, the traditional seasonal influenza, in northern China is usually the peak period in December each year to the next year in January, but the early arrival of this year’s peak season for influenza. In Beijing, for example, influenza-like illness increased significantly in late October day, there are 5000 cases of influenza-like illness about in previous years, flu has reached the peak level.
Liang years emphasized throughout the country within a short time into the Influenza A H1N1 influenza outbreak period, the probability of smaller, but the peak in different regions will be expected. Many schools have clusters of cases have emerged. Nin Leung said that with the influenza A H1N1 flu in China confirmed the increase in the number of cases, the emergence of cases of severe and death will be inevitable.
Minister of Health Chen Zhu said recently, said: “At present, although not Influenza A H1N1 influenza virus mutates, the majority of patients with mild disease, but the increasing cases of severe and death is inevitable.”
October 31 The statistics show that China’s current confirmed cases, more than 90 cases of cases of severe disease. Since October 2, had already reported six cases of deaths.
Liang years that the National Day holiday, the influenza epidemic developed rapidly, October 12, the nation’s influenza A H1N1 influenza cases reported over 15,000 cases, many of the local surge in patients with influenza-like symptoms, individual parts of the deaths, the epidemic by cities to the west, rural and ethnic minority areas continued to spread.
At present, China’s mainland network of 411 laboratories and 556 hospitals to carry out sentinel surveillance of influenza-like illness. Monitoring shows that, although the virus has not mutated, the clinical severity of the disease generally more moderate, but my general susceptible population, nearly 80% of influenza cases for the Influenza A H1N1 influenza patients. October 28 at a State Council executive meeting said that the coming period, the epidemic will continue to develop, the prevention and control situation is very serious.
A flow of the vaccine should not be vaccinated in the
June 8 this year, received from the World Health Organization can be directly used for vaccine production strains, to September 3 issued by the State Food and Drug Administration drug approval number, China’s first branch is also the world’s first branch of production batches to obtain Influenza A H1N1 influenza vaccine is only 87 days cycle.
Compared to the period of SARS and avian flu vaccines, our country can be developed in such a short period of time influenza A H1N1 influenza vaccine, causing many people to the vaccine safety and effectiveness questioned.
Experience has shown that vaccine is the prevention of infectious diseases, one of the most effective means. “The vaccine can be put into use as early as one day, as early as one day to protect priority groups and vulnerable populations, we can minimize the losses caused by an influenza pandemic.” Beijing Sinovac Biotech Co., Ltd., said Yin Weidong, managing director.
June to August, the State Food and Drug Administration have released the “good Influenza A H1N1 influenza vaccine production preparation work of the notice”, “pandemic influenza vaccine program of work of the special approval of emergency” and a series of documents, processing of applications for vaccine review laid the basis of a policy. From R & D to production, every step of strict compliance with “procedures are not reduced, the standard without compromising” principle.

My government regulations Influenza H1N1 influenza vaccination in accordance with informed consent, voluntary, free of charge principle. Before inoculation, vaccination was informed by the kinds of persons or their guardians vaccination species, role, contraindications, adverse reactions and precautions, asked by the kinds of persons in health status and whether there are contraindications such as vaccination, and to inform and asked questions truthfully record .
Domestic and international studies have shown that influenza A H1N1 influenza vaccine protection rate can reach more than 85% of its vaccination will greatly enhance the overall immunity to susceptible populations. At present, a total of eight influenza A H1N1 vaccine production, production of influenza vaccines, the ongoing protection of the vaccination priority groups. 10 31, China totaled 3.7878 million people of Influenza A H1N1 influenza vaccination, and will further accelerate the progress of vaccination.
