Boston (WBZ Newsroom) -- Swine flu claims two more lives in Massachusetts. The state Department of Public Health says both victims died of complications of the virus this week. One victim was a young child, the other a middle-aged adult. It's unclear whether either victim had any underlying medical conditions, but the DPH says serious swine flu cases are being seen even in people who are otherwise healthy. Since the outbreak began last spring, 17 people have died of swine flu related symptoms in Massachusetts.
