Actually, the symptoms of AIDS are not very typical. When it progresses to the AIDS stage, which is the late stage of the disease, symptoms such as unexplained persistent fever, weight loss, cough, chest tightness, diarrhea, phlegm, sore throat, swollen lymph nodes, rash, and others may appear. Some patients may also develop many white powdery deposits on the oral mucosa, and some may experience pain when swallowing. Different opportunistic infections have different symptoms.
