What is swine flu?

Swine flu (swine influenza)  is a disease of pigs. It is a highly contagious respiratory disease caused by one of many Influenza A viruses. Approximately 1% to 4% of pigs that get swine  flu  die from it. It is spread among pigs by direct and indirect contact, aerosols, and from pigs that are infected but do not have symptoms. In many parts of the world pigs are vaccinated against swine flu. 

How do people become infected?

The CDC says the spread of swine flu can occur in two ways: through contact with infected pigs or environments contaminated with the virus; or through contact with a person with swine flu. The CDC has determined that the virus is contagious and spreading among people, but at this time it is not known how easily that happens.

How common is swine flu infection in humans? 

In the past, CDC received reports of approximately one human swine influenza virus infection every one to two years in the United States.

How many swine flu viruses are there? 

Like all influenza viruses, swine flu viruses change constantly. Pigs can be infected by avian influenza and human influenza viruses as well as swine influenza viruses. When influenza viruses from different species infect pigs, the viruses can reassort (i.e. swap genes) and new viruses that are a mix of swine, human and/or avian influenza viruses can emerge. Over the years, different variations of swine flu viruses have emerged. At this time, there are four main influenza type A virus subtypes that have been isolated in pigs: H1N1, H1N2, H3N2, and H3N1. However, most of the recently isolated influenza viruses from pigs have been H1N1 viruses.

Symptoms Of Swine Flu (H1N1):
  1. Fever
  2. Cough
  3. Chills
  4. Headache
  5. Sore throat
  6. Vomiting
  7. Fatlgue
  8. Body Aches
Prevent Swine Flu Infection(H1N1):
  1. Wash your hands often.
  2. Cover your mouth and nose with a tissue when coughing or sneezing.
  3. Avoid touching your eyes, nose, and mouth.
  4. If you've got flu-like symptoms, avoid others until you've been free of fever for 24 hours.
  5. Stay at least 6 feet away from people with flu-like illness.
