Which of the following symptoms is most closely associated with meningitis?

Fever and neck stiffness are classic symptoms associated with meningitis, an inflammation of the protective membranes covering the brain and spinal cord. Meningitis often presents with flu-like symptoms, and fever is a common indicator of infection. The neck stiffness occurs due to irritation of the meninges, making it painful for individuals to flex their neck forward, a sign known as nuchal rigidity.

In the context of distinguishing meningitis from other conditions, the other symptoms provided are more indicative of different health issues. Pain behind the ear may suggest an ear infection or otitis media rather than meningitis. Black tarry stool, typically indicative of gastrointestinal bleeding or certain dietary factors, does not relate to meningitis. Eruptions on the skin could represent various dermatological conditions or infections, such as viral exanthems, but are not characteristic of meningitis itself. Recognizing the hallmark signs of meningitis, like fever and neck stiffness, is crucial for timely diagnosis and treatment.
