Swine Flu Claims 11th Life In Mass.

Massachusetts public health officials say a 26-year-old Martha's Vineyard resident has become the state's 11th swine flu death victim.

Unlike many young victims, the latest casualty announced Monday of the H1N1 virus had no known underlying health conditions.

Public Health Department Commissioner John Auerbach says the latest death is a reminder of how important it is to prepare for the upcoming flu season.

Many communities and school districts are currently formulating plans to deal with possible flu outbreaks, including Boston, where Mayor Tom Menino will convene a summit later this week with city, school, health and business leaders.

There have been 477 swine flu-related deaths nationwide.
