Meningitis is started when germs, either bacteria or viruses, enter the body. These germs typically spread through the air or direct contact with an infected person.
Germ Entry and Spread
Here's a breakdown of how meningitis begins:
- Initial Contact:
- A person catches the germs by breathing in mist or touching mucus or saliva from an infected person.
- This typically happens when an infected person coughs or sneezes.
- Entry Point:
- The germs enter the body through the nose or throat.
- Systemic Spread:
- Once inside, the germs quickly spread through the bloodstream.
- Reaching the Meninges:
- Finally, the germs reach the meninges, which are the membranes surrounding the brain and spinal cord.
- This causes inflammation that leads to meningitis.
Table: How Meningitis Spreads
| Stage | Description |
|---|---|
| Initial Contact | Breathing in mist or touching fluids from an infected person. |
| Entry | Germs enter through the nose or throat. |
| Bloodstream Spread | Germs travel through the bloodstream. |
| Meningeal Invasion | Germs reach the meninges, causing inflammation. |
Types of Germs
Meningitis is primarily caused by two types of germs:
- Bacteria: Bacterial meningitis is more serious and requires immediate treatment.
- Viruses: Viral meningitis is usually less severe and often resolves on its own.
In Summary
Meningitis begins with exposure to germs, either bacterial or viral. These germs enter the body through the nose or throat and spread through the bloodstream to the meninges, causing inflammation.
