TUCSON - Pima County health officials say a 13-year-old boy from Tucson has become the third person in Arizona to die with swine flu.

A spokeswoman says the teenager, a Tucson middle school student, died Friday of complications from the flu. He had been hospitalized May 10.

The Arizona Department of Health Services confirmed test results.

Spokeswoman Patti Woodcock says an older sibling is hospitalized with the virus, and other family members have recovered from the flu.

A Maricopa County woman was the first Arizonan to die with the flu virus about two weeks ago. The second fatality was a 57-year-old Pinal County woman who died last week.

Woodcock said health officials do not believe that other students at the boy's school � which was not identified � had contracted the illness.

She said the county has confirmed 87 cases of swine flu, with ongoing monitoring of virus activity continuing.

As of Tuesday, Arizona had 406 confirmed cases of swine flu in 10 of the state's 15 counties. The state's first case was identified on April 29.
