CLAYTON, Mo.- A 44-year-old St. Louis County man diagnosed with swine flu after traveling to Mexico has died.
The man's name was not released. Health officials said he died this morning at an undisclosed St. Louis area hospital.
Missouri Department of Health and Senior Services spokesman Kit Wagar said the man had a confirmed case of swine flu. But an autopsy and further testing is necessary to determine if the flu or an underlying illness killed him. That could take weeks.
Officials said the man traveled to Mexico last month, then became ill about a week after returning home. He went to his doctor, then to an urgent care center on May 9, then to the hospital.
If swine flu is confirmed as the cause of death, the man would be the first person in Missouri to die during the current outbreak of the disease. Five people in the U.S. have died, and another U.S. death is being investigated for swine flu.
Missouri has reported 20 cases of swine flu.
