Research indicates H1N1 may still be contagious after fever ends.

The AP reports that researchers with the Institute of Public Health in Quebec are reporting that the end of a patient’s coughing “is probably a better sign of when a swine flu patient is no longer contagious,” noting that the CDC “has been telling people to stay home from work and school and avoid contact with others until a day after their fever breaks. The new research suggests they may need to be careful for longer — especially at home where the risk of spreading the germ is highest. Swine flu also appears to be contagious longer than ordinary seasonal flu, several experts said.”
