Swine flue – Precautionary measures

Swine flue - Precautionary measures

Spread of influenza among swine can be prevented by the use of different methods like; facility management, hard management and vaccination. Control strategies that rely on vaccination may prove insufficient, as much of death and illness associated with swine flu involves secondary infection by pathogens. In recent decades, control of swine influenza has become more difficult. Evolution of the virus proved traditional vaccines to be inconsistent. When the virus strains match enough to have significant cross protection, then the standard commercial swine flu vaccines are effective. In more difficult cases custom vaccines are made from specific viruses isolated. Use of several bivalent SIV vaccines is included in the present vaccination strategies. 41 0ut of 97 H3N2 isolates examined had strong serologic cross reactions with antiserum to three commercial SIV vaccines.

Primarily, the protective status of the influenza vaccines depends on the closeness of the match between the vaccine virus and the epidemic virus. Current vaccine techniques may not effectively protect pigs from infection from majority of H3N2 viruses. Pig vaccination keeps pigs from getting sick but it doesn't block infection or shedding of the virus. Facility management comprises use of disinfectants and ambient temperature for controlling virus in the environment. Virus survives for more than two weeks outside the living cells, except in the cold conditions. Herd management comprises adding pigs, which carry influenza to herds that have not been exposed to virus. In healthy carrier pig virus survives up to 3 months and can be recovered from them between outbreaks.

In swine farms the transmission from swine to human occurs. The major method of limiting swine to human transmission includes use of vaccines to prevent their infection. Coughing and sneezing is the main reason for spreading this disease in human. Pork products can not spread swine, because this virus can not spread through food. During the first five days of illness, swine proves to be most contagious. Children can remain contagious for ten days. For preventing the spread of virus standard infection control against influenza is recommended. These measures include frequent washing of hands with soap and water. Alcohol based hand sterilizers can also be used, especially after being out in the public. The current trivalent influenza vaccine is unable to provide protection against the 2009 H1N1 strain. Vaccine may be ready by the end of June 2009. hand washing can prevent viral infections, ordinary influenza and swine flu virus. Droplets containing the virus can linger on tabletops, telephones and on other surfaces and help spreading the disease. They can be transferred via mouth, nose or eyes. To destroy viruses and bacteria alcohol based gel or foam hand sanitizers can be used. Sudden fever, muscle or aches are the symptoms of this disease. Another main tactic is the social distancing. Large gatherings should be avoided, spreading out a little at work and perhaps staying home are the other options. This disease can be prevented by using these simple techniques and to enjoy healthy life style.
