BEAWARE OF SWINE FLU
Today mostly spreading virus over human bodies is Swine Flu,Many country people are highly infected over the swine flu disease.Swine flu mainly occours from pigs ,people with regular exposure to pigs are at increased risk of swine flu infection. The meat of an infected animal poses no risk of infection when properly cooked.Swine flu are also called as H1N1 flu,hog flu,pig flu.These strains of swine flu rarely pass from human to human.The symptoms of swine flu would be fever,sore throat,muscle pain severe headache and coughing,weakness and general discomfort.Influenza C viruses infect both humans and pigs, but do not infect birds.In 1998, swine flu was found in pigs in four U.S. states. Within a year, it had spread through pig populations across the United States. Scientists found that this virus had originated in pigs as a recombinant form of flu strains from birds and humans.People who work with poultry and swine, especially people with intense exposures, are at increased risk of zoonotic infection with influenza virus endemic in these animals,Vaccination of these workers against influenza and surveillance for new influenza strains among this population may therefore be an important public health measure.
The transmission from swine to human is believed to occur mainly in swine farms where farmers are in close contact with live pigs. Although strains of swine influenza are usually not able to infect humans this may occasionally happen, so farmers and veterinarians are encouraged to use a face mask when dealing with infected animals. The use of vaccines on swine to prevent their infection is a major method of limiting swine to human transmission. Risk factors that may contribute to swine-to-human transmission include smoking and not wearing gloves when working with sick animals.
