What is bacterial meningitis and viral meningitis?
Meningitis is an infection of the tissues surrounding the brain and spinal cord (meninges). It is of different types like bacterial, viral and fungal. Meningitis caused by bacterial agents is termed as bacterial meningitis, meningitis caused by viral agents is termed as viral meningitis and meningitis caused by fungal agents is termed as fungal meningitis.
Similarity
- Few symptoms are similar in both types of meningitis like neck stiffness, headache, fever and dislike of lights.
Bacterial Meningitis
Infection of the meningitis caused by bacterial agents is termed as bacterial meningitis. It is most commonly caused by meningococcal bacteria. It is a serious infection and can even cause death of the individual suffering from this infection in as little as few hours if not treated in time. However, people suffering from this infection after taking antibiotics mostly recover from bacterial meningitis. One who delay the treatment or the condition become worse suffer from permanent brain damage, hearing loss and cognitive and learning disabilities. Vaccines are available for prevention of bacterial meningitis.
Bacterial meningitis spreads from one person to another through exposure or contact with fluids (oral and nose) of an infected person.
Viral Meningitis
Viral meningitis is caused by around 50 types of viruses. The most common virus that causes viral meningitis is termed as enteroviruses. It is usually mild and not serious. It often clears on its own and does not need any treatment. However, it is advised that anyone suffering from the viral meningitis should consult the doctor right away as it is important to find out whether it is meningitis or not, what is causing it, and the treatment option. Infants less than 1 month do not have a strong immune system and are at an increased risk of severe illness from viral meningitis. Vaccines are available for prevention of bacterial meningitis.
