Clinical Latency Stage
After the early stage of HIV infection, the disease moves into a stage called the clinical latency stage (also called "chronic HIV infection"). During this stage, HIV is still active but reproduces at very low levels. People with chronic HIV infection may not have any HIV-related symptoms, or only mild ones.
For people who aren't taking medicine to treat HIV (called antiretroviral therapy or ART), this period can last a decade or longer, but some may progress through this phase faster. People who are taking medicine to treat HIV the right way, every day may be in this stage for several decades because treatment helps keep the virus in check.
It's important to remember that people can still transmit HIV to others during this phase even if they have no symptoms, although people who are on ART and stay virally suppressed (having a very low level of virus in their blood) are much less likely to transmit HIV than those who are not virally suppressed
