Swine Flu Review



by Tofan Afandhi

Swine flu is now known as the H1N1 type of Mexico this is dangerous. Research based on Centers for Disease Control and Prevention United States, Mexico H1N1 type of flu is suspected strong combination of poultry, swine flu and human flu. Possible changes in the virus body pigs.

Virus that changes in the body of pigs may be more infectious to humans. Human and pig together mammals that tend to have similarities. Instead, bird flu can not be directly to humans. Theoretically, the virus in poultry does not go to mammals such as humans. There should be a mediator and other mammals is likely to pigs in the body of pigs, the virus changes with the two patterns. The first form of adaptation patterns. This is not too dangerous because there is no change in the structure of the virus. Pattern re-drafting a second virus. Based on this pattern, the virus can develop into a combination of swine flu, bird flu and human flu.

...

One is supporting the number of pig and poultry farm near, however, on the other hand, H1N1 type of violence does not like Mexican H5N1. From about 1500 cases in the world, only 150 ended with the death. H1N1 virus spread rapidly, but low power damage. On the slow spread of H5N1. However, the damage is very high Less than a month, Mexican H1N1 type has been infecting thousands of people. While in the past three years, the case of H5N1 was only about 300 cases in the world.

Director-General World Health Organization (WHO), Margaret Chan has warned that the potential pandemic. Mobility of people and agricultural products in international migration is likely cause of a virus that causes flu.

The researchers struggling to learn the characters that attack the virus. In general, the pig is the place converge different types of virus, both the attack itself pigs, poultry, and humans.
In the body of a pig allows perfect integration between the flu virus. In the pig's body, combining the various types of the virus occurred. The result will bring a new virus which contain the supporting material with the nature of the new body is a vehicle blender pigs (mixing vessel) will the coalition of various types of virus. In the body of swine flu virus with different types and subtipe can be mixed and produced "child" virus with a new character.
Until now the only body in the process of mixing of swine genetic material bird flu virus easily occur. This animal has a biological device that allows mixing the genetic material of the virus. Mixing the genetic material that begins when the virus into the pig's body. Human flu virus and the swine flu virus to enter cells through epitel pig reseptor alpha 2.6 sialic acid, while the flu virus into poultry reseptor alpha 2.3 sialic acid. Pigs have both reseptor it.

Cells in pig virus replication. At the time of virus replication that, among the virus that can occur or the exchange of genetic material, known as antigenic drift term. Each virus has genetic material in form eight fragments. Eight fragments are HA, NA, PA, PB1, PB2, M, NP, and NS. Fragment-fragment that can form tertukar to "children" with the virus of a different nature.

In the case of swine flu Mexico, re-regulation of the virus outside the structure with the same "mother", the pig flu virus (the virus because it is still called subtipe H1N1), but the material still comes from the human flu virus and bird flu. In addition to the going exchange genetic material, possibly also antigenic drift occurs, the fragments of mutation. When this happens, "children" have the virus genetic material is more complex. When antigenic shift and antigenic drift occurred in the case of swine flu in Mexico, this is the perfect change that Until now known that swine flu virus in Mexico "based" of the virus which is classified as low pathogenic, that is subtipe swine flu virus H1N1, subtipe human flu virus H1N1 and H3N2, and subtipe bird flu virus H5N2.

In fact, the level of violence subtipe bird flu virus H5N1 that reach 80 percent is greater than the swine flu virus that only 15 percent. However, with the rapid spread of the level, the basic framework of the virus is known swine flu virus. However, the contents or fragments of virus that consists of fragments of flu virus and the human flu virus of swine.

Health experts say, the virus that originated from the same types that cause infection in humans seasonal, but also contain genetic material from a version of flu that normally infect birds and pigs. Currently, four laboratories in the UK, Canada, the United States and the developing swine flu vaccine. The first vaccine is ready in 4-6 months. Required several days longer to produce the vaccine in large

Swine flu become new public enemies no 1. but is it real a new kind of desease? some fact said that there's something wrong with how this new desease appear..
SWINE FLU : IS IT A CONSPIRACY?
