Swine Flu

What is swine influenza?

Swine influenza, or “swine flu”, is a highly contagious acute respiratory disease of pigs, caused by one of several swine influenza A viruses. The virus is spread among pigs by aerosols, direct and indirect contact, and asymptomatic carrier pigs.

How do people become infected?

People usually get swine influenza from infected pigs, however, some human cases lack contact history with pigs or environments where pigs have been located. Human-to-human transmission has occurred in some instances but was limited to close contacts and closed groups of people.

Is there a human vaccine to protect from swine influenza?

There are no vaccines that contain the current swine influenza virus causing illness in humans. It is not known whether current human seasonal influenza vaccines can provide any protection. Influenza viruses change very quickly. It is important to develop a vaccine against the currently circulating virus strain for it to provide maximum protection to the vaccinated people. This is why WHO needs access to as many viruses as possible in order to select the most appropriate candidate vaccine virus.

How can I protect myself from getting swine influenza from infected people?

To protect yourself, practice general preventive measures for influenza:

* Avoid close contact with people who appear unwell and who have fever and cough.

* Wash your hands with soap and water frequently and thoroughly.

* Practice good health habits including adequate sleep, eating nutritious food, and keeping physically active.
