HEIDI COLLINS, CNN ANCHOR: SARS and the flu, similarities between the two illnesses lead to immune concerns among health experts and a new battle plan if there is another outbreak. Dr. Sandra Fryhofer is here now with more. So a lot of people are thinking that the SARS epidemic is definitely over. But I remember from when we were covering this story that there was the possibility that this disease, or virus, I should say, can lie dormant for a very long time and then come back.</s>DR. SANDRA FRYHOFER, CNN CORRESPONDENT: Well, you're exactly right, Heidi. And the epidemic was declared over by the World Health Organization back in July, but as you said, it's probably not gone for good. The CDC is concerned it might start showing up again just as flu season begins and they want doctors to be prepared. So, don't be surprised if you're asked to put on a surgical mask and go wash your hands when you go to the doctor if you have respiratory symptoms and expect your doctor and the nurses, and the nurse to do the same. And that's if there's no SARS reported. If there is a SARS outbreak anywhere in the world, expect to be asked on the phone about recent travel to a SARS infected area.</s>COLLINS: But you can never be too safe, that's for sure. So what about any new cases of SARS, do we know?</s>FRYHOFER: No new cases of SARS, but the flu epidemic has already started. It's now appearing in Houston, Texas and there's evidence that it's spreading to neighboring states, including Arkansas, Oklahoma and Louisiana. Alabama has also reported some cases. The best cure for the flu is prevention. So, go get your flu shot. It's not too late. Heidi, this one's for you if you want it later. Flu season does continue through February or March.</s>COLLINS: Probably a very good idea. All right, Dr. Sandy Fryhofer, thank you so much. Appreciate it, and I'll keep the mask.
