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:
The most common yeast infection in AIDS patients is called Candida albicans, which can affect the mouth (oral thrush) and the genital area (vaginal yeast infection). It is important for AIDS patients to seek medical treatment for yeast infections to prevent complications.
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.
Toxoplasma gondii is the most common protozoan associated with encephalitis in AIDS patients.
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.
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.
CD4+ T lymphocytes, also known as T helper cells, are severely depressed in AIDS patients. These cells play a key role in coordinating the immune response against infections. Decreased CD4+ T cell levels result in immune suppression, making patients more susceptible to opportunistic infections.
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.
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.
