Swine Flu

What is swine flu?

Like people, pigs can get influenza (flu), but swine flu viruses aren't the same as human flu viruses. Swine flu doesn't often infect people, and the rare human cases that have occurred in the past have mainly affected people who had direct contact with pigs. But the current swine flu outbreak is different. It's caused by a new swine flu virus that has spread from person to person and it's happening among people who haven't had any contact with pigs.

What are swine flu symptoms?

Symptoms of swine flu are like regular flu symptoms and include fever, cough, sore throat, body aches, headache, chills, and fatigue. Some people have reported diarrhea and vomiting associated with swine flu. Those symptoms can also be caused by many other conditions, and that means that you and your doctor can't know, just based on your symptoms, if you've got swine flu. It takes a lab test to tell whether it's swine flu or some other condition.

If I think I have swine flu, what should I do? When should I see my doctor?

If you have flu symptoms, stay home, and when you cough or sneeze, cover your mouth and nose with a tissue. Afterward, throw the tissue in the trash and wash your hands. That will help prevent your flu from spreading.

If you've got flu symptoms, and you've recently been to a high-risk area like Mexico, CDC officials recommend that you see your doctor. If you have flu symptoms but you haven't been in a high-risk area, you can still see a doctor that's your call.

Keep in mind that your doctor will not be able to determine whether you have swine flu, but he or she would take a sample from you and send it to a state health department lab for testing to see if it's swine flu. If your doctor suspects swine flu, he or she would be able to write you a prescription for Tamiflu or Relenza. Those drugs may not be required; U.S. swine flu patients have made a full recovery without it.
