Influenza

What is Influenza?

Influenza, often called the flu, is an infectious disease caused by special tiny germs called influenza viruses. It can make you feel very tired and give you symptoms like fever, runny nose, sore throat, muscle pain, headache, coughing, and feeling very weak (fatigue). In children, it can also cause diarrhea and vomiting.

How Does the Flu Spread?

The flu spreads mainly when someone who is sick coughs or sneezes. Tiny drops from their mouth or nose can go into the air, and others can breathe them in or touch contaminated surfaces and then their face. Aquatic birds are the main source of one type of flu virus, but it can spread among many animals and humans.

Staying Healthy

To help stop the flu from spreading, it’s important to practice good habits like hand washing and covering your mouth and nose when coughing or sneezing. Getting a flu shot every year is one of the best ways to protect yourself, especially if you are a young child, an older adult, or have health problems. These shots help your body recognize and fight the virus.

Fun Facts
