The family of a Scarborough man whose death has been linked to H1N1 flu says the 44-year-old diabetic was very healthy until developing a cough last week.

The father of two took some time off but went back to work on Friday because he was feeling better. He started feeling sick again later that day, according to his colleagues.

His family says he suddenly started coughing Saturday morning and couldn't stop. He was not responsive by the time paramedics arrived on the scene, and they were unable to revive him.

He leaves behind a wife and two young children.

Ontario's acting chief medical officer has said people with certain chronic medical conditions appear to be at greater risk of dying from swine flu if they catch it.
