Meningitis caused by viral or bacterial infections can be contagious and can be transmitted via cough, sneeze or close contact. Its symptoms include fever, headache, stiff neck, seizures, lethargy, sleepiness, among others. One disturbing symptom of bacterial meningitis is widespread skin rashes.

Meningitis can result in hearing and vision loss, memory issues, arthritis, migraine headaches, among others. A serious form of the disease can be fatal, can lead to gangrene, resulting in amputation, in many cases.
