Following a brief hospitalization, a woman from Waterbury died of swine flu on Tuesday, the Connecticut Department of Public Health announced today.

The woman was over 60 years old and at a higher risk for influenza-induced complications due to underlying risk factors, health officials said.

So far, 397 cases of the H1N1 flu have been officially confirmed in Connecticut, with the woman’s death being the first case that has proven fatal. Worldwide, 66 countries have reported over 19,000 cases of swine flu, with 117 of them fatal.
