People infected with HIV may experience a series of symptoms in the early stages of the disease, about two to three weeks after being infected with the virus. At this time, due to the virus's rapid growth and reproduction in the body, symptoms such as viral viremia can occur, including rash, fever, sore throat, and swelling of lymph nodes throughout the body. These symptoms are reversible and can subside after one to two weeks. Many people infected with HIV may not show any symptoms. The diagnosis of HIV is mainly confirmed through tests such as HIV antibodies, and it is not possible to infer HIV infection based merely on external symptoms.
