Viral meningitis is a condition that affects the protective membranes of the brain and spinal cord. Learn about its symptoms, causes, diagnosis, and safe treatment options in this quick guide.

What are the main causes of viral meningitis?

  • Viral meningitis is most commonly caused by enteroviruses, which spread through close contact, contaminated surfaces, or respiratory droplets from an infected person.
  • Other viruses, such as herpes simplex and mumps, may also trigger meningitis when they spread to the protective membranes around the brain and spinal cord.
  • Mosquito-borne viruses, like West Nile virus, can occasionally cause viral meningitis, making vector control important in affected regions.

Key symptoms of viral meningitis to watch for

  • Severe headaches and a stiff neck are hallmark symptoms, often appearing suddenly and causing significant discomfort in both adults and children.
  • Fever, nausea, and sensitivity to light are common signs, usually indicating the body’s immune response to the viral infection.
  • Fatigue, irritability, and confusion may develop, especially in children or vulnerable individuals, signaling that urgent medical evaluation is necessary.
