Disease accuses of the virosis of in the center and prevents and controls people's bird flu epidemic situation that the expert answers a question
The department of public health of Hunan Province notifies on the 20th, Hunan Province has made a definite diagnosis of a person and has infected with the high pathogenic bird flu case patient already in the death of about 10 past 8 a.m. on the 20th. This is following Beijing, Shanxi, Shandong, another person's bird flu case made a definite diagnosis of during one month. When being on the occasion of the Spring Festival, the appearing and making common people discuss " birds " constantly at one time of people's bird flu case The color changes. How on earth is the bird flu epidemic situation state of our country? Where is the emerging reason of people's bird flu case at present? How should the public take the measure of prevention and control to prevent people's bird flu To question these, reporter interview the intersection of China and disease accuse of the intersection of centre and virosis prevent and cotrol the intersection of Deputy Director and Shu consult Chen HuaLan, chief of the office of experiment, by YueLong and the intersection of country and the intersection of poultry and influenza 21. Ask: People the intersection of bird flu and epidemic situation recently will break out on a large scale Beijing make a definite diagnosis of infect the high pathogenic bird flu case by first people will it be January 6 2009. Hereafter, on the 17th, the 18th, 19 days of January, Shanxi, Shandong, Hunan Province made a definite diagnosis of the bird flu case in succession. At present, Beijing and the intersection of Hunan and patient die already, patient of Shanxi too condition critical. Fewer than one month, our country makes a definite diagnosis of 4 persons continuously and is infected with the high pathogenic bird flu case, but in 2008, the speaker is infected with 3 cases of high pathogenic bird flu altogether in the whole year in our country, cause the social high concern at one time. Does this mean the epidemic situation that people are infected with the high pathogenic bird flu is worsening at present? Will people's bird flu epidemic situation break out by a large scale? To the question that masses cared about these two most, Shu YueLong has denied clearly. Shu YueLong says, no matter seen from pathogenic analysis, or seen from investigation result of epidemiology, our country finds 4 cases of the report newly this year, have not gone beyond the characteristic of people's bird flu epidemic situation grasped in the past. In the past few years, no matter or abroad, people it infects with high pathogenic bird flu to be whether height send out in case. 4 cases of the new discovery report of our country are distributed in 3 provinces, a municipality directly under the Central Government this year, between have relation. January 11 of 2009, World Animals Health Organization (OIE) Secretary General Vallat says too, the person in the Chinese report is infected with the high pathogenic bird flu case is only a individual case at present, not worried for this. "Though several cases have appeared continuously in our country, people have been infected with the risk of the high pathogenic bird flu and increased, of our country the intersection of people and the intersection of bird flu and case present, send out highly, reason that case increase lie in section exactly bird flu high to take place period will it be spring winter. " Shu YueLong says. Statistics reveal, the spring of winter (from November to March of second year) that the morbidity time above the people bird flu case 70% of our country concentrates on ,Take southern province as the core on the region, exceed the city in the countryside. Shu YueLong says, it indicates, the virus is still birds' source, therefore can infer that the present virus is separated, the people of our country are infected with bird flu virus that bird flu circulated while still coming from the birds and polluting the environment at present. How about the bird flu epidemic situation state of our country? According to the introduction of Chen HuaLan, in 2008, the epidemic situation of 6 cases of bird flu takes place only in Tibet, Guizhou, Guangdong in our country, 9,000 poultry of onset, 9,000 pieces of death, slaughter 590,000; The onset counts, dies and counts and drops by 60.87%, 59.09% compared with the same period of last year separately, migratory bird's epidemic situation has not taken place either. Since June of 2008, the high pathogenic bird flu epidemic situation has not taken place in the whole country. "The immune state of bird flu of poultry of our country is good at present, the large-scale epidemic situation will not break out recently. " Chen HuaLan says, autumn will concentrate the great inspection of the immune work on seeing in the whole country in 2008 when notifies from the Ministry of Agriculture, the immune antibody qualification rate of bird flu is up to 86.7%, exceeding the country stipulates the standard, and is higher than in the past. Analyze, under the good immune state, the birds group can produce and protect strength effectively according to the epidemiology law, the large-scale epidemic situation will seldom take place. Shu YueLong shows too while predicting people bird flu epidemic situation of our country of this year, people's bird flu distributes the case to still have, but the possibility breaking out on a large scale in epidemic situation is not big. Two asks: What routes in a situation that the epidemic situation of bird flu has not taken place in the poultry people are infected with bird flu and had, people are infected with the bird flu case, this seems to be a paradox. But Chen HuaLan is analyzed and points out, it has multiple channels that people are infected with bird flu, first, contact and infect the poultry, second, contact and take the poisonous wild bird, third, contact the virus pollutant (food) Tasting and environment,etc.. The statistics show, more than 300 people who have already had 14 countries at present are infected with high pathogenic bird flu, with eating or contacting the thing (food) polluted by H5N1 bird flu virus more Taste and have something to do, certain amounts of patients infect the route unidentifiedly too. Chen HuaLan says, from sampling and monitoring the situation to see to living birds' market poultry and environment recently, and the situation of measuring the positive sample on the specific market, the hidden danger which propagates the epidemic situation exists to explain the living birds' market. Chen HuaLan says, since 2003, several million poultry and wild bird has been infected with H5N1 bird flu virus in the whole world, and through plant, field, forest, laboratory,etc., there are several million times at least in the chance that these animals contact with the mankind, but the messenger is infected only more than 300 cases in a few years, up till now, we have not discovered cultivating yet personnel and the veterinarian personnel have been infected with the bird flu case, it means and expose only a few people exchange the sense to bird flu virus in crowds. He says, though bird flu infects people and leads to the fact the reason why people die is still perplexing the experts of various countries, but the one that can confirm is, bird flu virus found at present, do not still possess the successors of people's condition, so the public needn't worry excessively. Shu YueLong expresses and approves this. He points out, the route overwhelming majority that known bird flu virus infects people is to pass the birds successor in the world at present, the successors of people's possibility is extremely limited. Through carrying on gene sequence and antigenic characteristic of separating for virus and analyzing to the bird flu case of the person of our country, the result indicates, bird flu virus that our country separates can be divided into 2 different groups, but all separation virus is birds' source, have not found the evidence that bird flu virus and the people influenza virus recombinate or mix again. In addition, 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. "Can infer people of our country infect, come from birds and bird flu virus that circulate pollute the environment, still at present. " Shu YueLong says. Three asks: How people's bird flu defends accusing of " analyze the bird flu epidemic situation situation of the people of the whole world and our countrying, infer of our country the intersection of people and bird flu send out case, appear constantly also, infect the intersection of source and clear case might remain as before, 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, so the prevention and control of bird flu still shoulders heavy responsiblities. " Speak of and defend Accusing of the situation, Shu YueLong says. The Ministry of Agriculture pointed out too recently, near on the Spring Festival, beasts and birds' products flowed frequently, the trading volume was large, have led to the fact the risk taking place and spreading in epidemic situation of domestic bird flu increases. For this reason, in order to guarantee not to happen high pathogenically? Olive Ling Shun ィ of Wan of Liang  Zan rosy clouds appearance of Gou's good fortune of naphthalene Block, would like the intersection of rock and  to be Ji awake to lead worried polonium Fu in harmony kang [Sao  detailed to mend the intersection of spring onions and  Xing compete, ask poor decayed tooth  play, brother of Fu, beak Polonium Fu ∫ Bu [whiz Suan in harmony of worried kang of Bi fresh school  of blue appearance? "Try hard to avoid contacting and taking in and dying of illness the birds, reduce the chance contacted with the living birds, defend people and is infected with the most effective precautionary measures of bird flu. " Shu YueLong says. He reminds the public to form the good personal hygienic habit at the same time, notices the raw prepared food dealt with etc. separately. Relevant experts say, the route that the mankind is infected with bird flu virus is mainly to keep in touch and infect. After the poultry is boiled well-donely, the virus can be killed, the possibility to travel is relatively small, have not found the case infected because of eating poultry and egg yet at present. But if the disease birds are not boiled well-donely and eaten, the virus may enter the human body. In addition, prevent the best method of people's bird flu, it is to keep sufficient sleeping and having a rest, carry on right amount of sports, strengthen one's own resistance, and strengthen indoor airiness, don't go to the place not good enough in airiness. Ministry of Public Health relevant person in charge remind the public whether prevail as infectious disease of coming down with, too, temporarily don't get the intersection of airiness and fine, the intersection of people and large public place. Have symptom of having a fever, coughing etc. want, seek medical advice in time, have poultry the intersection of contact and the intersection of influenza and kinds of symptom patient of history to need to seek medical advice in time, explain situation to exposed to poultry to doctor, make sure, find, rescue, cure the disease people early early, early report, preventing and cotrolling the epidemic situation early.
