Quebec health officials have confirmed that a second person in the province has died from the H1N1 flu virus.

Dr. Alain Poirier, Quebec's director of public health, said the victim is a Montreal man in his 40s who "had an underlying disease that lowered his immunity."

Earlier this week, an elderly woman over the age of 65 was first person to die from the H1N1 flu in Quebec.

Officials declined to offer any more details on the woman's identity because of privacy concerns.

The woman had been in hospital for three days suffering from flu symptoms. She also had a bacterial infection.

More than 800 Quebecers have so far been infected by the H1N1 virus.
