Individuals infected with HIV typically do not exhibit noticeable symptoms during the latency period. During the acute phase, however, symptoms such as rash, fever, generalized lymphadenopathy, and cough are likely to occur. During the active phase of AIDS, due to severe immune deficiency, a series of opportunistic infections and malignancies may occur. These can include persistent coughing, sputum production, diarrhea, weight loss, and unexplained fever. Treatment and diagnosis should be tailored to the specific circumstances, with diagnosis primarily made through testing for HIV antibodies.
