Everyone needs to stay calm. Remember SARS? That had the potential to be a far worse situation because it was a bacteria that was resistant to even the strongest antibiotics. It had a very high fatality rate. Eventually it fizzled out after everyone began taking precautions.
At least so far with this swine flu in the U.S., cases have been mild and it is responding to anti-viral medications.
Keep in mind the 24 hour news channels need people to stay worried so they keep tuning in to their stations for breaking news. In my opinion, they are feeding the fear.
Just use your common sense: If you don't feel well, drink fluids, rest and if you are running a fever or get worse, see the doctor.
Keep washing your hands and cover your mouth when you sneeze and cough.
I believe it will be okay and usually I am a very anxious, pessimistic person.
