The flu is caused by an influenza virus.
How the Flu Spreads
The primary way people contract the flu is through the following:
- Airborne Droplets: When someone with the flu coughs or sneezes, they release tiny droplets containing the virus into the air. Inhaling these droplets can infect you.
- Surface Contact: The influenza virus can live on surfaces. If you touch a surface with the virus on it and then touch your mouth, nose, or eyes, you can get the flu.
Common Misconception
It's important to remember that colds and the flu are different illnesses caused by different viruses. People often mistake them for one another.
Key Takeaway
In summary, the flu is caused by an influenza virus, primarily spread through airborne droplets and surface contact. Understanding this can help you take preventative measures to protect yourself.
