What is Seasonal Influenza (Flu)?
Seasonal flu is a contagious respiratory illness caused by a virus. It can cause mild to severe illness, including death.
Typically in Iowa flu season peaks in February but can occur as early as October and as late as May.
Common symptoms of flu are fever of 100F, cough and/or sore throat, funny or stuffy nose, headache or body aches, chills and fatigue.
Most people who get the flu feel better with in one or two weeks.
Many people use “stomach flu” to describe illness with nausea, vomiting or diarrhea. Many different viruses, bacteria, or parasites can cause these symptoms. While the flu can sometimes cause vomiting, diarrhea, and nausea—more commonly in children than adults — these problems are rarely the main symptoms of the flu.
The flu is a respiratory disease and not a stomach or intestinal disease.
