Answer

Meningococcal meningitis is characterized by acute onset of intense headache, fever, nausea, vomiting, photophobia, and stiff neck. Elderly patients are prone to have an altered mental state and a prolonged course with fever.

Lethargy or drowsiness in patients frequently is reported. Stupor or coma is less common. If coma is present, the prognosis is poor.

Patients also may complain of skin rash, which usually points to disease progression.

The clinical pattern of bacterial meningitis is quite different in young children. Bacterial meningitis in these patients usually presents as a subacute infection that progresses over several days.

Projectile vomiting may occur in children.

Seizures occur in 40% of children with meningitis, typically during the first few days. The majority of seizures have a focal onset.

In infants, the illness may have an insidious onset; stiff neck may be absent. In children, even when the combination of convulsive status epilepticus and fever is present, the classic signs and symptoms of acute bacterial meningitis may not be present. [3]

The Waterhouse-Friderichsen syndrome may develop in 10-20% of children with meningococcal infection. This syndrome is characterized by large petechial hemorrhages in the skin and mucous membranes, fever, septic shock, and DIC.
