Carriage of HIV also means that the patient is infected with AIDS. Carriage of HIV means that the patient is infected with AIDS, but there are no obvious clinical manifestations and the patient is able to live with the virus. Although the virus continues to replicate in the patient’s body during this period, CD4+ T-lymphocytes remain at relatively high levels, so the patient does not have an opportunistic infection. If the virus continues to replicate and CD4+ T-lymphocytes continue to decline, the patient will eventually enter the AIDS stage and develop a variety of opportunistic infections, such as Pneumocystis pneumonia, Cryptococcal meningitis, Candida albicans esophagitis, herpes zoster, etc. Eventually, the patient will die due to opportunistic infections and malignancy.
