Patients with HIV go through an acute phase, an asymptomatic phase, and an AIDS phase after infection. The acute phase usually lasts for about 4 weeks and is characterized by transient fever and other symptoms, after which the patient enters the asymptomatic phase, which can last for about 6-8 years. During the asymptomatic phase, the majority of patients have no obvious symptoms. Eventually, patients will enter the AIDS stage, after which they will develop various opportunistic infections, and most patients will die due to opportunistic infections or malignant tumors. Most patients will die from opportunistic infections or malignant tumors. Therefore, once diagnosed with AIDS, patients should be treated with antiretroviral drugs as soon as possible to avoid progression to the AIDS stage.
