Respiratory disease caused by the influenza virus is often referred to as swine flu. Swine flu is also known as pig, swine, and hog flu. Swine flu is the zoonotic disease transfer from pig to the human. The occurrence of this disease marks the serious panic around the globe. Swine flu has become pandemic in 1918 killing more than 100 million people around the globe due to this occurrence of this disease is considered a serious health concern. There are various strains of the virus such as H1N1, H2N1, H3N1, H2N1, H3N2 and H2 N3.
Symptoms of the swine flu are common to these of influenza that comprise a sore throat, fever, headache, coughing, and marked by the decrease in appetite (1).
To diagnosis, the swine flue oral and nasal fluid is analyzed.
The infestation of the virus causes several weights lose in the pig affecting the economic benefit from it. Although the mortality is relatively low excessive weight loss can be devastating to the farmers in this industry. Further prevention, control, of the disease requires the huge sum of money.
Transmission is from the direct contact with the pig. There is evidence of the transmission by the airborne droplets. An airborne droplet during the coughing and sneezing is the major cause of human-to-human transmission. Contact with any material contaminated with the virus leads to the transmission of the disease. The incubation period is between 4 to 6 days. Swine flu is not transferred by eating the pork meat or other pork products (2).
Prevention from the swine flue requires several integrated efforts. There is the need of following the strict safety procedure to prevent the infection. Wearing the globe, washing the hand with soap water, unnecessary touching of animals needs to avoid. The virus becomes inactive in one or two weeks outside the living cell. Adequate sterilization needs to be carried out in the place infested by the virus. It is best to avoid the crowd during the time of epidemic as the virus transmitted by the sputum from the sneezing.
Vaccines are commercially available for the preventing the infection from the swine flu. Due to the rapid evolution resistance to the vaccine by the virus administration of the vaccine can be of nugatory value.
