Suffolk County health officials say two Brookhaven residents have been confirmed as Long Island's first deaths due to swine flu.

Suffolk Health Commissioner Humayun Chaudhry says the first two people to die from the H1N1 virus are adults who had underlying medical problems, including pneumonia and fever. According to Chaudhry, one victim was a retired woman between the ages of 55 and 65 who died June 9. The second victim was a man between 35 and 45 years old, who died June 10.

At a news conference, Chaudhry said the victims did not know each other, work in schools, or have contact with anyone from Mexico, where the outbreak was first reported April 26.

Chaudhry says the deaths are sad, but not unexpected. He cautions Long Islanders to wash their hands frequently and stay home and seek medical attention if ill. Chaudhry says people may not associate summer weather with the flu, but residents should remain aware.

Officials have not released the names of the victims.
