At the customary news briefing of Ministry of Public Health held on January 12, Ministry of Public Health requires, all types of medical organization should strengthen and monitor efforts during the Spring Festival, especially find the acute infectious disease case including bird flu in time, report in time. If the medical organization does not cause finding, report by human factor in time in diagnosis of the infectious disease case, will deal with strictly at the request of prediction scheme. Most cases take place to the phenomenon which some the public worries about to the appearance of the epidemic situation of bird flu very much in the spring of winter, China CDC ( Center for Disease Prevention and Control) Notified characteristic and progress for the prevention and control of the present people's bird flu epidemic situation a few days ago. Deputy Director, national influenza researcher Shu YueLong, director of centre claim that China CDC virosis prevents and cotrols, by January 7 of 2009, 15 countries will find that make a definite diagnosis of 393 bird flu virus H5N1 case of person in the whole world, among them 248 die, case fatality rate exceeds 60%. A person's bird flu case of the report of Beijing, find the 31st person's bird flu virus H5N1 case made a definite diagnosis of in the hinterland of our country recently, also the case the 21st dies. YueLong Shu introduce, global the intersection of people and the intersection of bird flu and several case have illness coming on in the spring of winter, the age median of the case is 18 years old, any age bracket has illness coming on. The case fatality rate of the group is higher than the crowd of group over 50 from 10 years old to 19 years old. The morbidity of different gender is counted and the case fatality rate difference, without the significance. But between 20 years old and age group of 39 years old, women's case fatality rate is higher than men. The people bird flu case epidemiology characteristic of our country is generally the same with the whole world, 77% of the people's bird flu case has illness coming on and concentrates on from November to Winter-Spring in March of next year season, the age median of the case is 29 years old, among them more than half case is smaller than 30 years old. Case come loose, take place, jump dragon, point out known bird flu virus it infects routes of people to be the intersection of birds and spread to reach people mainly at present while being easy more, exposed to dying of illness directly the birds are the most common dangerous factors, eating has not been had a potential danger too by the poultry products of deep processing. The living birds' market of visit is infected with and had illness coming on the possible dangerous factor by the urban case. Nearly 1/4 of the cases infect the source not clear, still can't get rid of the environment to people's spread route. It is introduced, a prominent characteristic of people bird flu virus H5N1 epidemic situation is, the case is highly distributed. Since 2003, 10 countries have reported 45 gather venereal disease example, more than 90% of the gathering venereal disease examples take place in the kinsfolks who have blood relationship and live together in the whole world, a few are neighbours, friends or persons from the same area. Gather the intersection of venereal disease and the youngest 1 year old under example, most large 80 year old, smaller than 40 year old group, account for 92%. Men and women's case is counted and is similar to. The majority gathers the venereal disease example and exists together and exposes the history, but there are limited person successors under the circumstances that the intimate health is exposed to the prerequisite. H5N1 case of our country, except that two Nanjing cases gather the venereal disease exception for the family, the others are distributed. 30 cases and 30 county Districts distributed in 14 provinces, and take southern province as the core (27) ; Rural case ( 18) Exceed the urban case ' 12) . 15 once direct or mediate contact die of illness birds before not having illness coming on ' Have made a definite diagnosis of animal's epidemic situation of bird flu in 4 case sites) ,Had lived on birds' market before 17 had illness coming on, one infected the source not clear. One has attended to the remakable bird flu patient for a long time before having illness coming on ' Its son) ,This case is greatest through being exposed to the possibility that respiratory tract secretion and intestinal excrement of its son are infected directly, but can't totally exclude the possibility that it is infected on living birds' market. All separation whether the intersection of birds and source jump dragon, say our country separate to 23 virus, H5N1 of bird flu, in making a definite diagnosis of case already while being easy in virus, the intersection of Beijing and virus of case that make a definite diagnosis of newly separate the work and is in progress. So far, the virus that all separation gets is birds' source, have not found bird flu virus and the people influenza virus are recombinated or mixed the evidence again. It is still birds' source that the receptor specificity of the virus connects peptide characteristic with the antigen of hemagglutinin, different from people influenza virus, and with the high homology of virus from separating in the birds of our country. After analyzing animal and human world bird flu epidemic situation situation of the whole world and our country, Shu YueLong infers, the people of our country are infected with bird flu virus circulated while still coming from the birds and polluting the environment at present, people bird flu send out the case, appear constantly even. And increase a case newly each time, will be all worthy of improving it and propagating ability and creating the chance among persons again through the mutation of adaptability or gene for the virus. Two major monitoring systems are caught the strange researcher of home of horse of director of China CDC information center of epidemic situation of person's bird flu and introduced, our country set up and launched people's bird flu monitoring system in 2004, monitored pneumonia of unidentified reason nationwide, meet an urgent need and monitor when animal epidemic situation and people's bird flu case of bird flu take place, search for people's bird flu epidemic situation. Among them, pneumonia of clear reason monitors and requires to report the unidentified reason pneumonia case in time in all types of medical organization, diagnose and arrange and look into the work SARS and people's bird flu case laboratory at the same time, work of public health of handling etc. that and launch the epidemic situation. Meet an urgent need, monitor, require in the animal epidemic situation or people's bird flu case of bird flu takes place in 3 kilometers of areas, influenza one kind of symptom cases and persons who keep in close touch of companion launch monitoring voluntarily to generating heat. These two kinds of monitoring systems complementing one another have played an important role in people's bird flu prevention and control in our country. The bird flu case overwhelming majority of person that our country made a definite diagnosis of was found through the unidentified reason pneumonia monitoring system. Meet an urgent need monitoring system find 1 the intersection of people and the intersection of bird flu and case respectively in 2005 and 2007 separately. Horse's family is strange Say, the unidentified reason pneumonia report has already become the important component of the straight newspaper system of epidemic situation of network of our country. As global unique national infectious diseases and online straight newspaper networks of public health information, this system has already covered the above hospital and 80% of the health clinics in towns and townships at county level of 96% of our country now. Have not eaten and is familiar with? Huan Sun's raw meat quiet ��? Fear poultry's food because of bird flu to some people, Chinese CDC office director, disease accuse of meeting an urgent need and going through person in charge researcher Wang Jian to point out, it is to infect source, spread route and more easily infected group to form 3 key elements that infectious disease propagates, lack any among them and can't infect. At present, there is not a person's bird flu case that because ate the well done poultry and infected in the whole world. Wang Jian says, the people of our country are not used to eating the raw meat, helping people's bird flu prevention and control. People want trying hard to reduce and poultry, the chance which the poultry contact that especially die of illness, don't slaughter, eat and die of illness the poultry. If must keep in touch, should notice that wears gloves to operate, pay attention to growing and separating skillfully. Wang Jian briefs on, preventing bird flu should pay attention to the personal hygiene, especially the hygiene of hands, and then wash hands before a meal.
