The young and healthy who feel invincible from the H1N1 “swine flu” influenza pandemic may not be as bulletproof as they think, warn public health experts.
Nearly two-thirds of Canadians hospitalized due to swine flu, and half of those who have died, had no underlying health conditions.
Experts do not yet understand why the new strain affects some healthy people so severely, ravaging their lungs with an aggressive pneumonia and forcing them to spend weeks in hospital, attached to breathing machines.
