Swine flu
swine influenza, or swine flu, is a respiratory disease in pigs caused by a certain strain of type A influenza virus. Outbreaks of swine flu are not common among humans: Most people who get swine flu are infected through contact with pigs.
How it spreads
Although people typically get swine flu from contact with pigs, there have been cases of person-to-person transmission. Experts think coughing, sneezing and contaminated surfaces can spread the infection among people, but it is unknown how easily that happens.
The virus cannot be obtained by eating properly cooked pork or any pork product.
Symptoms
The symptoms are similar to those of the common flu: fever, cough, sore throat, body aches, headaches, chills and fatigue.
Symptoms of diarrhea and vomiting have also been reported. infection from the virus can lead to severe illness, including pneumonia and respiratory failure, and can be fatal.
Treatment
Antiviral drugs, such as oseltamivir or zanamivir, are recommended for the treatment or prevention of swine flu. Antiviral drugs are prescription medicines that keep flu viruses from reproducing in the body. Antiviral drugs work best if treatment is started within two days of the onset symptoms.
