In general, the average duration of asymptomatic HIV infection in adults is about 6-8 years, depending on the individual. The asymptomatic HIV infection period is one of the stages of the disease, which occurs after the acute HIV infection period, when most patients have almost no symptoms, and a few may have enlarged lymph nodes. In addition, the duration of asymptomatic AIDS infection is closely related to the length of infection, the number and type of viral infections, the route of infection and the immune status of the body. It is important to note that the HIV virus is still present during the asymptomatic period of infection and can be transmitted through breastfeeding, blood and sexual intercourse.
