Summary Introduction
To determine:
The two nervous system infection most likely to occur in HIV-positive patient and also discuss the pathogenesis of the disease.
Introduction:
"AIDS" (acquired immunodeficiency syndrome) is not a disease but a syndrome which is caused by a virus "HIV" (human immunodeficiency virus). This virus infects the CD4 cells disease weakens the immune system, making the patient vulnerable to infections and diseases.
