SAN FRANCISCO (AP) - New studies show that many people with swine flu may be able to spread the virus for a week or more after symptoms first appear. That's longer than some experts had thought.
Health officials have been telling people to avoid contact with others for a day after their fever goes away. The new research suggests they may need to be careful for longer, and that coughing is a more accurate sign of how long they can spread the germ.
The research was discussed Monday at a microbiology conference in California.
