Meningitis Differential Diagnosis

Similar Diseases	Differentiating Factors
Encephalitis	Encephalitis primarily affects the brain
Flu	Flu typically presents with respiratory symptoms
Migraine	Migraine headaches are usually recurrent and not associated with fever
Viral Gastroenteritis	Viral gastroenteritis primarily presents with gastrointestinal symptoms
Bacterial Sinusitis	Sinusitis primarily affects the sinuses, whereas meningitis affects the meninges
Pneumonia	Pneumonia primarily affects the lungs, while meningitis affects the meninges

Meningitis can be distinguished from similar diseases like encephalitis or flu based on affected areas (meninges or brain) and specific symptoms. Accurate meningitis diagnosis requires clinical evaluation and tests.
