Coughing may be a better sign than fever of when people can spread swine flu, studies suggest. When the coughing stops is probably a better sign of when a swine flu patient is no longer contagious, experts said after seeing new research that suggests the virus can still spread many days after a fever goes away.

Health experts meeting in San Francisco have expressed confidence that a fresh (A)H1N1 outbreak can be contained, as the northern hemisphere braces for its winter flu season.

WASHINGTON (Reuters) - One million heart attacks, 700,000 strokes and 900,000 miscarriages -- U.S. public health officials want Americans to know these will happen every single year with or without a swine flu vaccine campaign.

US says swine flu vaccine supplies still tight but maker of nasal-spray version may help. The U.S. may have as many as 160 million doses of swine flu vaccine available sometime in October, even though manufacturers worldwide are having serious trouble brewing shots, federal health officials said Thursday.

Swine flu shot campaign could involve 600M doses; officials wonder how to administer them all. A potential fall swine flu immunization campaign may involve an unprecedented 600 million doses of vaccine, though officials said Friday they haven't figured out how to administer so many doses or accurately track side effects if a seasonal vaccine is given simultaneously.
