What you need to know about swine flu


"Individuals have a key role to play," Dr. Richard Besser, acting chief of the Centers for Disease Control and Prevention, said Monday.

Here's what you need to know:

Q: How do I protect myself and my family?


Q: How easy is it to catch this virus?



A: The CDC says there's not good evidence that masks really help outside of health care settings. It's safer just to avoid close contact with someone who's sick and avoid crowded gatherings in places where swine flu is known to be spreading. But if you can't do that, CDC guidelines say it's OK to consider a mask – just don't let it substitute for good precautions.

Q: Is swine flu treatable?


Q: Is there enough?

A: Yes. The federal government has stockpiled enough of the drugs to treat 50 million people, and many states have additional stocks. As a precaution, the CDC has shipped a quarter of that supply to the states to keep on hand just in case the virus starts spreading more than it has so far.

Q: Should I take Tamiflu as a precaution if I'm not sick yet?

A: No. "What are you going to do with it, use it when you get a sniffle?" asks Dr. Marc Siegel of New York University Langone Medical Center and author of "Bird Flu: Everything you Need To Know About The Next Pandemic." Overusing antiviral drugs can help germs become resistant to them.

Q: How big is my risk?

A: For most people, very low. Outside of Mexico, so far clusters of illnesses seem related to Mexican travel. New York City's cluster, for instance, consists of students and family members at one school where some students came back ill from spring break in Mexico.
