In the past, people’s awareness of influenza A (H1N1), due to the distance, is only in theory. With the beginning of the epidemic in some local areas of Luzhou (mainly in some schools) in the last week, the rapid progress of the epidemic has led to panic about the disease, which is a normal phenomenon, because many people have experienced a pandemic of infectious diseases, especially students. Here, people are urged to be scientific. A, influenza A (H1N1) virus and ordinary influenza virus like! Although the genotype of these two viruses are different, but in the outside world are relatively low resistance to ethanol, iodophor, tincture of iodine and other common disinfectants are very sensitive to heat sensitivity, 56 ℃ conditions can be inactivated in 30 minutes. Second, why is this local epidemic sudden and fast progressing? This is fully consistent with the general epidemiological characteristics of respiratory infectious diseases, the reason is that the influenza A H1N1 virus, unlike ordinary influenza virus, is a new genotype, human beings completely lack of immunity to it, so people are generally susceptible; second is the climate factor, the Luzhou area from the September high temperature weather quickly into the colder climate in October, the human body physiological functions have not yet adjusted, resulting in The resistance of the body is reduced. Why is the disease spreading so rapidly? This is mainly due to the path of transmission of the disease is determined. Influenza A (H1N1) virus infects the human body is mainly in the upper respiratory tract mucous membrane replication, so the disease is usually through the upper respiratory tract of the card he symptoms (such as cough, sputum, sore throat, sneezing, runny nose, etc.) generated by the droplets out of the body, thereby spreading to others. Therefore, this pathway is most likely to gather in a crowd and the air does not circulate in the place to achieve, which is also prone to aggregation of school morbidity is one of the important reasons. Fourth, how is the prognosis of influenza A (H1N1)? Through the close observation of the local patients of this type found that almost all cases of the disease are relatively light, often naturally remitted after 2-3 days of illness, and we have experienced in the past the common cold almost. This is as self-limiting as other acute viral infectious disease manifestations. Therefore, the majority of cases have a good prognosis and there is no need to be hospitalized in isolation for observation and treatment. V. Which cases can be arranged for home isolation observation and treatment? They are cases with only general flu symptoms, including fever, runny nose, nasal congestion, sore throat, cough, headache, myalgia, malaise, no lower respiratory tract infection, no other complications, and non-influenza high-risk groups. And there is no need to actively apply the treatment of the neuraminidase inhibitor Oseltamivir, a potent drug against this virus, and only give general treatment: rest, drink more water, and closely observe the changes in the condition; antipyretic treatment can be given to high fever cases, and drugs containing aspirin (acetylsalicylic acid) are prohibited to prevent the emergence of Richter’s syndrome. Sixth, what are the high-risk groups that are likely to become serious cases? The following groups of people with flu-like symptoms, more likely to develop into serious cases, should be given high priority, as soon as possible for influenza A (H1N1) virus nucleic acid testing and other necessary tests: women during pregnancy; with the following diseases or conditions: chronic respiratory disease, cardiovascular disease (except hypertension), kidney disease, liver disease, hematologic disease, neurological and neuromuscular diseases, metabolic and endocrine diseases system diseases, immune suppression (including the application of immunosuppressants or HIV infection, etc. resulting in immune depression), long-term aspirin users under 19 years of age; obese people (high risk of body mass index ≥ 40, body mass index of 30-39 may be a high-risk factor); children aged < 5 years (age < 2 years is more prone to serious complications); elderly people aged ≥ 65 years. Seven, which cases should be hospitalized in isolation for observation and treatment? In addition to the more likely to become a serious case of influenza A (H1N1) high-risk group of people with the onset of influenza A (H1N1), one of the following cases of other cases of influenza A (H1N1): persistent high fever > 3 days; severe cough, coughing pus sputum, bloody sputum, or chest pain; rapid respiratory rate, breathing difficulties, blue lips; mental changes: unresponsiveness, drowsiness, agitation, convulsions, etc.; severe vomiting, diarrhea, dehydration manifestations; imaging Pneumonia on imaging; rapid increase in creatine kinase (CK), creatine kinase isoenzyme (CK-MB) and other cardiac enzymes; significant aggravation of existing underlying diseases. Any of the above should be recommended for hospitalization for observation and treatment. VIII. What should I do if I have cold-like symptoms? If you have cold-like symptoms such as fever, runny nose, nasal congestion, sore throat, cough, headache, myalgia, and weakness, do not panic. Because this season, in addition to the current epidemic of influenza A (H1N1), there are also common seasonal influenza, other viral and bacterial infections of the upper respiratory tract, and early manifestations of other respiratory infectious diseases. Therefore, it is advisable to rest at home, drink more boiled water, take some Chinese medicines for colds appropriately, and if the body temperature is high (over 390C), you can take some antipyretic and analgesic medicines without aspirin such as paracetamol; if there is still no obvious relief after 2 days of observation and treatment at home, it is recommended to go to a regular hospital fever clinic for medical treatment. Remember: go to work or school before your condition is completely relieved and your body is not fully recovered, and also try to go out as little as possible.
