When does one know that you have to seek doctor?

I saw a movie-documentary on National Geographic about bird flu. The actor got sick and her symptoms looked like the regular flu and it was only because the cleaner of the hotel insisted of getting in and do the regular clean up that a doctor was called, because it looked so innocent. Not to mention the fact that regular flu can also be dangerous. I have been told about a young doctor who got flu and she was dying.

How does one know if your sneezing is not only an innoncent cold or flu but a H5N1 or regular flu that has just been dangerous to you?

Where are you located? If you are in the U.S., then it is unlikely that you have the avian flu -- as far as I know, it has not yet mutated into a virus that travels from human-to-human, and has also not yet made an appearance in the U.S. in a person. I could be wrong, but that's the last I heard ...

edit:
Actually, I just looked at the CDC site about avian flu (which I recommend you do as well, as they discuss symptoms) and there was a case in 2002 in Virginia, but again, there have been NO documented human-to-human cases.
