Influenza (flu) is a viral infection. People often use the term “flu” to describe any kind of mild illness, such as a cold or a stomach virus, that has symptoms like the flu. But the real flu is different. Flu symptoms are usually worse than a cold and last longer. The flu usually does not cause vomiting or diarrhea.
Most flu outbreaks happen in late fall and winter.
