Swine Flu FAQ

How does swine flu spread? Is it airborne?

The new swine flu virus apparently spreads just like regular flu. You could pick up germs directly from an infected person, or by touching an object they recently touched, and then touching your eyes, mouth, or nose, delivering their germs for your own infection. That's why you should make washing your hands a habit, even when you're not ill. Infected people can start spreading flu germs up to a day before symptoms start, and for up to seven days after getting sick, according to the CDC.

The swine flu virus can become airborne if you cough or sneeze without covering your nose and mouth, sending germs into the air.

The U.S. residents infected with swine flu virus had no direct contact with pigs. The CDC says it's likely that the infections represent widely separated cycles of human-to-human infections.

How is swine flu treated?

The new swine flu virus is sensitive to the antiviral drugs Tamiflu and Relenza. The CDC recommends those drugs to prevent or treat swine flu; the drugs are most effective when taken within 48 hours of the start of flu symptoms. But not everyone needs those drugs; many of the first people in the U.S. with lab-confirmed swine flu recovered without treatment. The Department of Homeland Security has released 25% of its stockpile of Tamiflu and Relenza to states. Health officials have asked people not to hoard Tamiflu or Relenza.

Is there a vaccine against the new swine flu virus?

No. But the CDC and the World Health Organization are already taking the first steps toward making such a vaccine. That's a lengthy process -- it takes months.

I had a flu vaccine this season. Am I protected against swine flu?

No. This season's flu vaccine wasn't made with the new swine flu virus in mind; no one saw this virus coming ahead of time.

If you were vaccinated against flu last fall or winter, that vaccination will go a long way toward protecting you against certain human flu virus strains. But the new swine flu virus is a whole other problem.

How can I prevent swine flu infection?

The CDC recommends taking these steps:

• Wash your hands regularly with soap and water, especially after coughing or sneezing. Or use an alcohol-based hand cleaner.
• Avoid close contact with sick people.
• Avoid touching your mouth, nose, or eyes.

Can I still eat pork?

Yes. You can't get swine flu by eating pork, bacon, or other foods that come from pigs.

What else should I be doing?

Keep informed of what's going on in your community. Your state and local health departments may have important information if swine flu develops in your area. For instance, parents might want to consider what they would do if their child's school temporarily closed because of flu. That happened in New York City, where St. Francis Preparatory School in Queens closed for a couple of days after eight students were found to have swine flu.  Don't panic, but a little planning wouldn't hurt.
