What's not to trust?
Seriously, see the previous response to another poster above ...
There are other medical personnel there to observe now (NOT that they are *entirely* trustworthy either) PLUS we're working on it now (in this hemispere) and I'm *sure* they would hate to be 'shown up' working for a cure/coming up with the specifics of how this bug spreads and propagates ...
OTHERS have pointed out the weakness that poor hygene gives to these viral agents - and I think the populace is now 'scared' enough to start taking sneezing in public and other 'risky health practices' a little more seriously.
