What is the reason why people with HIV/AIDS often die?

a. The illness makes people susceptible to meningitis, which in turn shuts down the body's ability to produce the lymphocytes that are used to ward off bacterial and viral illness. b. The virus attacks the liver and pancreas which together produce insulin and bile. You cannot live without these two substances, so as the illness further damages these organs, life cannot be sustained by the body. c. The illness compromises the body's ability to fight illness, so the patient dies of other sickness or disease. d. The virus causes cancer, most notably of the colon, rectum, and testicles, and these very dangerous forms of cancer explain why so many more men die of HIV/AIDS as compared to women.
