SEATTLE - A Washington state man with underlying heart conditions became the third person infected with swine flu to die in the United States, health officials said yesterday, while Costa Rica reported the first swine flu death outside North America.
Japanese authorities, meanwhile, scrambled to limit contact with their country's first cases, and Australia and Norway joined the list of nations with confirmed cases of swine flu.
A Snohomish County man in his 30s died Thursday from what appeared to be complications from swine flu, the state Department of Health said in a release. The man had underlying heart conditions and viral pneumonia at the time of his death, but swine flu was considered a factor in his death, the statement said.
