What is the Difference Between Viral and Bacterial Meningitis?
🆚 Go to Comparative Table 🆚Viral and bacterial meningitis are both infections of the tissues covering the brain and spinal cord, known as the meninges. They are caused by different pathogens and have distinct characteristics:
Viral Meningitis:
- Caused by viruses, most commonly non-polio enteroviruses in the United States.
- Symptoms include fever, headache, neck stiffness, nausea, and vomiting.
- Usually less severe than bacterial meningitis and often resolves on its own without treatment.
- Not passed on to others through close contact.
Bacterial Meningitis:
- Caused by bacteria, most commonly Streptococcus pneumoniae and Neisseria meningitidis.
- Symptoms include fever, headache, neck stiffness, nausea, and vomiting.
- More severe than viral meningitis and can be life-threatening.
- Can be passed on to others through close contact.
- Requires immediate medical attention and treatment with antibiotics.
It is crucial to seek medical attention if you suspect meningitis, as early treatment is vital for a full recovery. The specific cause of meningitis should be identified to determine the appropriate treatment.

Comparative Table: Viral vs Bacterial Meningitis
Here is a table comparing the differences between viral and bacterial meningitis:
Feature | Viral Meningitis | Bacterial Meningitis |
---|---|---|
Causes | Viruses, most commonly non-polio enteroviruses, herpes simplex virus, and influenza viruses | Bacteria, such as Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type b |
Severity | Generally less severe, almost never life-threatening | More severe, can cause brain damage, hearing loss, or learning disabilities |
Symptoms | Fever, headache, dislike of lights, neck stiffness, and sometimes a rash | Similar symptoms as viral meningitis, but with fever, neck stiffness, and altered mental status |
Treatment | Usually resolves without treatment, symptom-specific medications may be used | Antibiotics are essential for treatment, with early diagnosis crucial for better outcomes |
Prevention | Vaccines for measles, mumps, rubella, varicella, and influenza can help protect against some viruses that cause meningitis | Vaccines for meningococcal and Hib bacteria are available, but not all bacterial meningitis can be prevented |
Contagiousness | Not typically passed on through close contact | Can be spread through contact with fluids, such as saliva or stool |
Age Affected | Can affect anyone, most common in adults and older children | Can affect anyone, but more common in young children |
It is essential to consult a doctor if you suspect meningitis, as early diagnosis and treatment are crucial for better outcomes, especially in bacterial meningitis.
