The average person infected with HIV develops into an AIDS patient in about 9 years or so. The time is variable, some shorter, around 1-2 years, and some up to a decade or more, and is related to the number of HIV infections. Many AIDS patients develop the disease as an opportunistic infection, either due to lung disease, central nervous system infection, or malignant tumor, and their clinical manifestations vary. Some patients may have other symptoms, such as prolonged low-grade fever, chronic diarrhea, weight loss, white spots in the mouth, etc. Therefore, for patients with AIDS, if the diagnosis is clear, antiretroviral treatment is needed in a timely manner. The patient’s condition will gradually improve with early antiviral treatment.
