Final answer:
CMV encephalitis is a viral infection of the brain, while cryptococcal meningoencephalitis is a fungal infection that affects the brain and surrounding membranes. Both infections have different causes and symptoms.
Step-by-step explanation:
CMV encephalitis, caused by the cytomegalovirus (CMV), is a viral infection that affects the brain. Symptoms include fever, fatigue, swollen glands, and pharyngitis. In serious cases, it can lead to encephalitis, convulsions, coma, and even death.
Cryptococcal meningoencephalitis, caused by the fungus Cryptococcus neoformans, is an infection that usually starts in the lungs and then spreads to the brain. Initial symptoms include fever, fatigue, and a dry cough. If left untreated, it can lead to meningitis, which produces headaches, sensitivity to light, and confusion.
