Authorities say the woman in her late 60's died at Tripler Army Medical Center June 19. It's unclear how she caught the virus but state epidemiologist Dr. Sarah Park said it was too much for the already sick woman.

"The patient was already in quite a precarious state," Dr. Park told reporters, "and it was one thing or another that could have contributed and this did not help that person."

It is the first death tied to H1N1 in Hawaii out of a total of 545 confirmed cases.

Another Oahu resident was hospitalized over the weekend after the infection led to pneumonia. This comes as the state is investigating several other swine flu cases within the Molokai Fire Department. The Health Department initially reported an outbreak there, that 20 members had come down with the illness. The Health Department said it got that information from the Maui District Health Office. But, that number is being disputed.
