The flu is caused by an influenza virus.
Understanding the Cause of Flu
Influenza, commonly known as the flu, is a respiratory illness that can cause mild to severe sickness. According to health information, the direct cause of this contagious disease is a specific type of pathogen.
Key Cause:
- The flu is caused by an influenza virus.
These viruses primarily infect the nose, throat, and lungs. There are different types and strains of influenza viruses, which is why you can potentially get the flu more than once in your lifetime.
How Flu Viruses Spread
Understanding how the virus moves from person to person is crucial in preventing its spread. The influenza virus is highly contagious and spreads mainly through airborne droplets.
Methods of Transmission:
- Airborne Droplets: Most people get the flu when they breathe in tiny airborne droplets from the coughs or sneezes of someone who has the flu. When an infected person coughs, sneezes, or even talks, they release virus-containing droplets into the air.
- Surface Contact: You can also catch the flu if you touch something with the virus on it, and then touch your mouth, nose, or eyes. The virus can survive for a short time on surfaces like doorknobs, phones, or handrails.
This table summarizes the main ways the flu virus spreads:
| Method of Spread | Description |
|---|---|
| Airborne Droplets | Breathing in particles released by coughing, sneezing, or talking. |
| Contaminated Surfaces | Touching objects with the virus and then touching your face (mouth, nose, eyes). |
Preventing the Spread
Awareness of how the flu spreads helps in taking steps to protect yourself and others. Simple actions like washing hands frequently, covering coughs and sneezes, and avoiding touching your face can significantly reduce the risk of infection.
