Beijing Chaoyang hospital breathes and critical the disease medical department's associate professor of treatment Cao ZhiXin from nearly several months case of the global report is counted and can be seen, the new first type H1N1 influenza epidemic situation keeps growing in intensity, " influenza prevails in era big " Have already come. Then, what kind of scene is represented before our eyes? Breathing the professional doctor as one, I talk about situation and view found out about by oneself. The epidemic situation may last the epidemic situation of this influenza of longer time would start in March of this year, find the new first type H1N1 influenza case in U.S.A. and Mexico initially. Northern Hemisphere annual influenza high to take place season usually from November to March next year those years, so this new influenza appears when general seasonal influenza finishes exactly. Over one month, people have placed hope on being transferred with the weather in Northern Hemisphere to the epidemic situation of warm influenza and will be relieved to some extent, but turn out contrary to one's wishes. The present epidemic situation situation indicates, the climate factor seems that has not obviously influenced this spread strength of new influenza virus, not merely in Northern Hemisphere ' Such as North America, Europe) ,And in the Southern Hemisphere ' Such as Australia) ,The spreading trend appears in influenza. Can want to see, if present epidemic situation develop further, it extends to next influenza to be high to take place season. So, the epidemic situation of influenza may last more than 6 months even one year. New influenza has two characteristics of relatively lower characteristic influenza virus of strong, pathogenic strength of contagiousness that determine the severity of the epidemic situation. First, contagiousness. Because crowds generally lack immunity to such new influenza virus, this influenza demonstrates stronger contagiousness, shown as the case is counted and increased rapidly in the world, a lot of take place to break out and prevail in environments such as the school,etc.. Second, pathogenic strength. Patient's proportion and case fatality rate of serious disease weigh two indexes of the pathogenic strength of influenza virus. According to having materials now, only 2%~5% first type H1N1 influenza make a definite diagnosis of a patient to need hospital treatment in U.S.A. and Canada, this proportion is 6% in Mexico, prove the patient's proportion of serious disease influenza is not high. According to the data on June 11, the case fatality rate that global first type H1N1 influenza makes a definite diagnosis of the patient is 0.5%, this is a relatively lower figure (2003 SARS case fatality rate 7%~13%, the case fatality rate of great influenza of 1918> 2.5%) . Influenza large prevailing danger lie in short time appear a large number of patient high to take place season in general influenza, 5%~15% in population can present upper airway infection and symptom, and great for influenza while prevailing The population up to 1/3 may be infected. The danger with great and prevailing influenza is lying in this: Influenza patient presenting the huge quantity within relatively short time, even patient's proportion and case fatality rate of serious disease are not high, also will present absolute serious disease and death patient larger in quantity because of huge patient's base figure, thus make health epidemic prevention and medical treatment system face the pressure greatly, greater influence emerges to the whole society. The high-risk group to be laid special stress on protecting influenza of high-risk group have meaning of two layers. First, easy to be infected the crowd of influenza, mainly have persons who keep in close touch with the influenza patient for a long time due to working reasons, such as medical worker, public health personnel,etc.. Second, apt to present the crowd with taller serious complication, case fatality rate after suffering from influenza. It is generally acknowledged to children, old man, pregnant woman, have chronic patients who are the high-risk group. Adopt strong prevention and control and treatment means to the high-risk group, can be in order to lower influenza patient's proportion and case fatality rate of serious disease notably. This new influenza, besides demonstrating the above-mentioned characteristic to a certain extent, have some and seasonal difference of influenza, until patient healthy at ordinary times in the intersection of Mexico and about 50% death, as to this need to make and further summarizing analysis. It is to deal with the foundation with great and prevailing influenza to understand and cooperate with implementing the formulation and implementation taking government as leading tactics of prevention and control to the measure of prevention and control. Our country has already delayed the spreading of epidemic situation to a certain extent through enclosing and stopping up the tactics to inputting first type H1N1 influenza case. It is large and prevailing in the world with influenza, the native country of our country has illness coming on originally the example may increase gradually, even appear influenza and break out and prevail, the tactics of prevention and control of our country will carry on corresponding adjustment too. Understand and cooperate and implement the measure of prevention and control, it is every citizen's due obligation of ours. Who does it chain person who keeps in close touch influenza mean in adopt protect situation effectively, diagnosing, treating or attending to, visiting first type the intersection of H1N1 and the intersection of influenza and person of patient; Have lived together with the patient or had personnel that have contacted at short range; Have contacted patient's respiratory tract secretion, the humoral one directly; May be exposed to personnel of environment or object which the patient pollutes,etc.. The person who keeps in close touch influenza needs to observe segregation medical science for 7 days.
