Flu

Flu season is underway in the United States, and a new report shows that flu activity is already higher than typical for this time of year.

U.S. health officials said they are concerned the upcoming flu season could be a bad one, based on reports from the Southern Hemisphere.

If this vaccine works in humans, it could mean one shot and you're protected for life from the flu virus.

Although there is no sure-fire way to avoid catching a cold or the flu, there are a number of things you can do to reduce your risk of these illnesses this fall and winter.

Researchers in Georgia have developed a "microneedle patch" that can deliver the flu vaccine through a person's skin.

Would you be more likely to get your flu vaccine if, instead of getting a shot, you could simply apply a bandage-like patch to your skin?

Researchers looked at the cases of nearly 300 U.S. children who died from the flu over four flu seasons.

A particularly deadly strain of avian flu, currently found in China, has infected more people there this flu season than it has in any season since the virus was identified, a new report finds.

U.S. health officials expect flu activity to remain elevated for at least a few more weeks, according to a new report.
