We feel confident that there won't be an outbreak. The people who were around the patient are now being identified and traced by the CDC and by the state health authorities. ... you get people, you identify them, and you observe and monitor them daily to determine if they develop symptoms If they do, then you put them under isolation to determine if, in fact, they are infected.

Testing two vaccines against different H1N1s at the same time has never been done.

We can sharply deflect the curve of HIV incidence.

Exposures, if they are mild, in the sense of barely just a small concentration, it's mostly an irritant, particularly the peroxides, that in that smoke would irritate the skin or even irritate the lungs. So, for the most time, it could be either just a little bit of a nuisance irritant, or if you get a really big whiff of it, particularly people who have, for example, reversible airways disease, like asthma or different types of hypersensitivity diseases, you could get a serious problem.

You can have an epidemic in a state. You can have it in a region. You can have it in a country where the critical level of disease passes a certain threshold and we call that an epidemic threshold.

There cannot be any impediment to science that will ultimately be good to the general public.

Activism has been very productive in our society.
