Meningitis is inflammation of the meninges, the membrane surrounding the nervous system.
Cause of meningitis
Meningitis is usually due to viral (often Coxsackie A virus) or bacterial (Meningococcal, Streptococcal) infections. It may occur spontaneously or develop following surgery or head injury
Symptoms of meningitis
Viral meningitis is common and mild whereas bacterial meningitis is rarer but far more severe. Fever and shivering, headaches, vomiting, photophobia and phonophobia (pain from light and sound), and neck stiffness are observed.
Treatment of meningitis
Treatment involves administering medicines which combat the infection (antiviral agents or antibiotics) and which relieve the symptoms. Vaccines are also available to avoid certain infections.
