Meningitis :
Meningitis is a condition that describes inflammation of the protective membranes covering the brain and spinal cord. It is generally caused by bacteria or viruses, more rarely by fungus or another infection. Although viral meningitis is typically less severe and clears on its own, this condition can occasionally be quite serious, like bacterial meningitis, which is a life threatening emergency. Other symptoms are headache, fever, neck pain and stiffness, light and noise sensitivity as well as confusion to the point of delirium, and in some cases, seizures. Infants may have symptoms that include increased irritability and bulging of the skull. The infection is transmitted by coughing or sneezing very close person to person. Treatment is based on the cause. Bacterial meningitis requires immediate hospitalization with antibiotics and supportive treatments, whereas viral meningitis may require just rest and fluids in extreme cases with pain relievers. The Meningococcal vaccine can help prevent some types of meningitis. Prompt recognition and intervention are very important to prevent complications such as brain injury or deafness.
