The answer is, no. Hospitals are not required to report cases of the
flu. State health officials say cases of H1N1 are no different than cases of the seasonal flu; they are not required by any kind of law to report them. In peak flu season there are thousands of cases and each year there are thousands of deaths as well.
The state does track cases in about twelve hospitals, it's part of
their flu activity surveillance. The state does lab testing on cases
submitted from those hospitals to try and get a better gauge of what's
going on in different areas and to keep track of the numbers.
State health officials say deaths in children related to the seasonal
and h1-n1 flu are reportable by law. The Centers for Disease Control
keeps tabs on those numbers.
