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.
