Series I of Influenza A(H1N1)———Unveil the Influenza A(H1N1)

The spring in 2009, which should be full of sunshine, fantasy and unlimited sentiment, is particularly unusual. All people around the world are overshadowed by the haze of financial crisis, decreasing economics and the increasing unemployment. Nevertheless, human suddenly suffered a surprising attack of Influenza A(H1N1) （formerly known as swine flu). The new type of flu, just like a flood, swarms into every corner of the world, endangers the life of some people, disrupting the life of common people, and put the whole world into great fear. So, what kind of A(H1N1) virus is? How do it spread and rage around the world? The following would lift the veil to let us know about H1N1, and we would not excessively tense once we have correct understanding on it, it would also help to placate our unpeaceful motion as well as establishing calm mind.

Influenza A(H1N1) (formerly known as swine flu) is a kind of porcine respiratory disease caused by Type A Flu virus, periodic outbreaks of the virus could cause the sick of the pig. There are many different types of Influenza A(H1N1), the current case have relation with H1N1 of Type A Flu virus. A/H1N1 Flu belongs to swine-respiratory disease which is irritable and infectious. At the beginning of infecting the virus, people would sense like get an ordinary flu, but the temperature would suddenly raise to more than 38 ℃, the body also would accompany with increasing sense of muscle soreness, dizziness, headache, diarrhea, vomiting and other symptoms. Human's infecting of A/H1N1 Flu may be through direct contacting with infected pig or infected environments or infected person. A/H1N1 Flu spread fast and could spread in the crowd. The main spreading method of the virus in the crowd is through coughing and sneezing of the patients. The patients who died mainly ranges from 25-45 years old, the group of which belongs to young adults, rather than children and old man. The symptom would not show any symptom until the virus latent in the body for seven days. Therefore, once a man show symptom of flu, it must be paid more attention. The death rate of A/H1N1 is 6.77% and it is relative higher than ordinary flu; there are mainly two reasons for the high rate of death: first, suddenly outbreak; second, people would initially think it is the common cold, and do not serve special medicine, miss the best 72-hour treatment period at the beginning of the outburst.

Because that the symptom of A/H1N1 flu is similar with common flu, almost everyone would treat and deal with it like common flu at the early phase of the flu. However, experts claim that, current medicine, which has significant effect on common flu, has less or even no effect on A/H1N1. So at current stage, when there are no drugs which can significantly resist against the virus, preventive measure becomes more and more important.

Although Influenza A(H1N1) is different from ordinary flu or bird flu, there are a lot of things in common with them. Because that flu virus usually spread among the human world and the animal world, all the virus which cause the sick of human, birds and swine are different. Seasonal flu is caused by virus which is adaptable for human, while bird flu is cause by virus which is adaptable for birds; people have natural immunity to resist against common flu and could enhance their immunity through vaccination. Similarly, Influenza A is caused by virus which is adaptable for swine. This virus could stimulate same respiratory symptoms and could be spread from one body to another.

Countries in the world have been taking various of preventive measures, such as monitoring, isolating, to resist against it in succession, and it becomes more important for us to pay highly attention on the situation, so as to prevent it from raging around great China which has large amount of population. Recalling the past, the rampant spreading of SARS still make the mass tremble with fear, we can not even withstand another plague while we just finished one. So we must maintain sharp vigilance on the situation. It is not only the responsibility of the government, but also the concern of ourselves, thus, we must lead an example to take care of ourselves, treasure our life, protect ourselves, and at the same time share the burden of the country.

When facing with this grim situation, WHO warned that, the outbreak of the epidemic "has the possibility of large-scale spreading around the world", and it also recommends every country to strengthen the supervision and the preparation work so as to prevent the fast spreading of the virus. In addition, Flu virus has strong capability of variation and mutation, which makes it difficult for the drug manufacturers to ensure the effectiveness of the vaccine. The new variant of H1N1 is the compound body of virus of different animals and human, and the human almost have no immunity to against the variant virus. In view of this circumstances, human must strengthen the defensive measure to control the virus within smaller scope, we must also emphasize on everyone and everything so as to eliminate the spreading of the disease.
