Meningitis and Fever: Understanding the Connection

Fever is common in meningitis but not universal—especially in elderly, immunocompromised, or very young infants.

Mechanism: Pathogen components (LPS, peptidoglycan) trigger pyrogen release → hypothalamic set-point elevation.

Other Key Symptoms

• Severe headache
• Nuchal rigidity (stiff neck)
• Photophobia
• Nausea/vomiting
• Altered mental status (confusion, lethargy)
• Seizures
• Petechial/purpuric rash (meningococcemia)

Meningitis is a medical emergency. If suspected, seek immediate ER evaluation—delay increases mortality and neurologic sequelae.
