What is it?

According to the CDC, swine influenza (swine flu) is a respiratory disease of pigs caused by type A influenza viruses that cause regular outbreaks in pigs. People don't normally get swine flu, but human infections can and do happen. Swine flu viruses can spread from person-to-person, but in the past, this transmission was limited and not sustained beyond three people.

Is it contagious?

Yes. But how the virus is spread is unknown.

What are the symptoms?

The CDC says symptoms include fever, cough, sore throat, body aches, headache, chills and fatigue. Some people have reported diarrhoea and vomiting associated with swine flu. In the past, severe illness (pneumonia and respiratory failure) and deaths have been reported with swine flu infection in people. Also, like seasonal flu, swine flu may cause a worsening of underlying chronic medical conditions.

How can you get it?

You can "catch" swine flu the same way you get sick from other flu viruses: From person to person through coughing or sneezing of people with the virus. You could also become infected by touching something with flu viruses on it and then touching your mouth or nose. You don't get swine flu from eating pork or pork products. Eating properly handled and cooked pork products is safe.

How can I stay healthy?

* Wash your hands often with soap and water, especially after you cough or sneeze.

• Try to stay in good general health: get your sleep, stay physically active, manage your stress, drink fluids, and eat nutritious food.
  Try not touch surfaces that may be contaminated with the flu virus and avoid close contact with people who are sick.
  There's no vaccine at the moment, but here are some other tips to avoid contracting the virus:
  
  • Cover your nose and mouth with a tissue when you cough or sneeze (then throw the tissue in the trash!)
    Avoid touching your eyes, nose or mouth.
    And if you get sick, stay home from work or school and limit contact with others to keep from infecting them.
