AIDS patients are susceptible to a variety of infections, commonly known as opportunitistic infections. They are so named because the infections take advantage of a person's weakened immune system to strike.
Among the most common infections are:
Probably either pneumonia or Kaposi's Sarcoma.
Kaposi's sarcoma
Kaposi's Sarcoma
Many fungal infections are called opportunistic infections, which means, Some disease-causing fungi are more common in certain parts of the world it is common, high-risk HIV patients.
Aids attacks blood cells which fight infections, which weakens the immune system
From taking immunosuppressive drugs, transplant patients are susceptible to the same "opportunistic" infections that threaten AIDS patients--pneumocystis pneumonia, herpes and cytomegalovirus infections, fungi, and a host of bacteria.
The specific opportunistic infections that AIDS patients develop depend in part on the prevalence of these infections in the geographic area in which the patient lives. See related link.
Once a person with HIV progresses to have AIDS (in 8-10 years on the average), his immune system is so weak that many common infections begin to attack him. Diseases like Pneumonia, TB, some specific cancers, fatigue, vision loss, brain damage are commonly occurrences among AIDS patients. Death results eventually if these infections (called "opportunistic" infections) are unchecked.
Bacterial infections
AIDS patients are typically on a variety of antiretroviral medications to try to suppress the HIV virus and boost the immune system. In addition, if oppportunistic infections appear, medications are used to treat those infections.
toxoplasmosis
more than two million patients develop hospital-acquired infections in the United States each year. About 90,000 of these patients die as a result of their infections.
It pretty much disables your immune system, meaning you are wide open to infections, viruses, etc It's not the AIDS that kills you as such, but other infections and viruses that were only allowed to grow and harm you because AIDS had killed your immune system.
AIDS is Acquired Immune Deficient Syndrome. Actually, it's Acquired Immuno Deficiency Syndrome. Addendum: it's the 3rd stage people go through after an infection with HIV. Basically, your immunodeficiency system fails, so you get all kinds of "common" diseases, and nosocomials (bacteria,fungi,... that live in and on your body without causing trouble) also cause infections. When untreated, AIDS patients die from the combination of a lot of "common" infections. I assume AIDS Sensitisation is informing people about this disease, so that they can take precautions, but also don't overreact when having contact with an aids patient.
Most lesions that patients view as "spider bites" have nothing to do with spiders, and are, in fact, staph infections.
