An influenza pandemic - an epidemic that covers many countries and continents, in fact - the whole world. Human history has known several influenza pandemics. Each such a pandemic - a huge number of cases and deaths, huge economic losses. The most famous, the infamous pandemic - is the famous "Spanish flu" or the Spanish flu - A (H1N1). "Spanish flu" - the most terrible, the most tragic pandemic flu. Absolutely no reliable information, but according to some studies, in 1918-1919. Influenza A humanity paid the price of 40-50 million (!) lives. Asian flu. A virus (H2N2). The pandemic of 1957-1958. Two million dead. Hong Kong flu - A (H3N2). 1968-1969. One million. One appeared in the world a new type of influenza A virus among humans and cause a pandemic. But after that the virus does not disappear. Continues to circulate in human society and is the cause of sporadic cases of the disease. But, as most people with this type of virus antibodies have been epidemic becomes impossible. Nevertheless, the further in time from coming off mankind pandemic of the less people have antibodies to a particular embodiment the virus. It is clear in fact, that in 1959 (at the end of the Asian flu pandemic) in the world inhabited by billions of people with immunity to influenza A (H2N2). Years passed ... Number of people who have antibodies to A (H2N2), diminished. And again you can expect from this virus epidemic. One consolation is only one thing - if you really expect an epidemic of A (H2N2), then doctors and scientists know it is about this version of the virus almost everything: age and epidemiological characteristics of the disease, typical symptoms, possible complications. That is, the unpleasant waiting, but at least it is known what to expect. But with the emergence of a new virus in principle reason for the unrest is more than real. As soon as we started talking about the symptoms, epidemiological features, and so on, look at this in more detail. Thus, the influenza virus is common in all countries and on all continents. The peak incidence is usually necessary to cold (winter) months. Is largely due to a more active, more intimate communication of people (children) in schools, kindergartens and transport. Again, the exchange of indoor air can not be compared with that in the warmer months. The windows are closed, all struggling with drafts and cherish the warmth is so active that room ventilation is seen as an attempt to freeze the others. The main mode of transmission of the virus from person to person - airborne. Coughing and sneezing, plus transport and accommodation with an absent air exchange, plus a crowd of people - logical and predictable result: the rapid spread of infections and epidemics. The air influenza virus retains its activity for up to four hours. By the way, there are certain characteristics - resistance of influenza A is higher than that of influenza B virus but both "love" low temperature - the optimum figure of about 4 ° C. Pronouncing the word "like", we mean that it is at this temperature the virus persists for a long time. At the same time, the ideal temperature for reproduction - is the temperature of the human body. Virus contained in the drops of saliva and phlegm, after the droplets dry and sag, such as linen, retains its activity for about two weeks and room dust - five weeks! Very interesting illustration about the stability of the virus. The research showing that influenza virus can persist for a long time the banknotes. And the described phenomenon can largely influence the intensity of the epidemiological process. The most persistent in this regard is a strain of H3N2: a dried on paper nasal secretions, he remained active up to 17 days! At the same time, almost all disinfectants flu virus is easily killed and the standard wet cleaning with the use of these funds - a great way to disinfect the premises. And if you add room ventilation and washing clothes - so the local victory over the virus for more than real. The incubation period of the flu - from one to three days. The patient is contagious for 24 hours before the first symptoms. This, incidentally, is one of the factors that make it impossible to prevent the spread of infection by various travel restrictions and quarantine measures. Onset of the disease is almost always sharp: that is, virtually no such that today 37,5 ° C, 38 ° C tomorrow, day after tomorrow 39 ° C. As a rule, faster: like an hour ago everything was in order - and all of a sudden 39 ° C, chills, and head hurt. By the way here's one of my friend used honda engines The average duration of fever perioda6 - 3-5 days, but it is necessary to take into account the fact that the patient is contagious 1-2 days after normalization of body temperature. Flu symptoms are non-specific: that is, not the flu is nothing that can not be observed in other viral respiratory infections. When compared with the bulk of other viruses that have a tendency to the fact that the temperature increase is more pronounced, more likely to have myalgia, headache, runny nose is less pronounced. In other words, the main and most characteristic symptom of the flu - it's not a stuffy nose, cough and 37,5 ° C, a condition marked by the words "not bad at all." One of the sites of partners used honda engines Here it is worth noting that the principal feature, now no longer the influenza virus, and actually a disease called "the flu", is the dominance of the general toxic syndrome syndrome respiratory tract lesions. However, this basic feature is noteworthy is in the early days of the disease, and as the temperature normalization and improvement of the general condition of the fore catarrhal phenomena (cough, stuffy nose, etc.). To finish up the subject of influenza, it remains to actually pay attention to four issues: • Complications; • Prevention; • Laboratory Diagnosis; • Treatment. The author is well aware that it is concerned with these questions readers most. Meanwhile, the vast majority of methods of diagnosis, prevention and treatment are the same for all SARS. And there are no complications that can occur with flu, but fundamentally impossible with other viral respiratory infections. That is why we will return to these topics later, in fact, consider them in great detail and will devote to each of the four separate issues of this book.
