What is a classic sign of possible meningitis in a child?

A classic sign of possible meningitis in a child is sensitivity to light and a stiff neck, known collectively as photophobia and nuchal rigidity, respectively. Meningitis is an inflammation of the protective membranes surrounding the brain and spinal cord. The stiffness in the neck results from irritation of the meninges, making it painful or difficult for the child to bend their neck forward. Photophobia occurs as light can cause discomfort or a headache, a common symptom associated with meningeal irritation.

In the context of meningitis, these signs are crucial for early recognition and prompt medical intervention, as the condition can progress rapidly and require immediate treatment. The presence of both symptoms strongly suggests the possibility of meningitis and warrants further evaluation.
