Detailed explanation-1: -Following acute HIV infection, most people enter a period of clinical latency in which they have few or no symptoms. This period may last decades or only a few months, but most infected persons will progress to AIDS over several years.

Detailed explanation-2: -Stage 2: Clinical Latency People in this stage may not feel sick or have any symptoms. This stage is also called chronic HIV infection. Without HIV treatment, people can stay in this stage for 10 or 15 years, but some move through this stage faster.

Detailed explanation-3: -People with chronic HIV infection may not have any HIV-related symptoms. Without ART, chronic HIV infection usually advances to AIDS in 10 years or longer, though in some people it may advance faster. People who are taking ART may be in this stage for several decades.

Detailed explanation-4: -Incubation period of HIV The interval from HIV infection to the diagnosis of AIDS ranges from about 9 months to 20 years or longer, with a median of 12 years.

Detailed explanation-5: -This stage is also called asymptomatic HIV infection or clinical latency. HIV is still active and continues to reproduce in the body. People may not have any symptoms or get sick during this phase but can transmit HIV. People who take HIV treatment as prescribed may never move into Stage 3 (AIDS).
