After HIV has caused such a reduction in immune cells that the body can no longer fight off illness, a person will be diagnosed with AIDS. Common signs of AIDS are opportunistic infections, such as Kaposi's sarcoma, pneumonia, candida, and eye infections. Severe weight loss, brain tumors, night sweats, chronic diarrhea, swollen lymph nodes, severe shaking from chills, and high fever are also some of the most common symptoms.
