Your CD4 count begins to increase in this time but may not return to the previous amount before the virus invasion.

Clinical Latency: The disease then moves into a stage called clinical latency. This period is sometimes known as asymptomatic HIV infection or chronic HIV infection. During this phase, HIV reproduces at very low levels, but it is still active.. You may not have symptoms or infections at this stage_._ This period can last up to 8 years or longer. Some people go through this stage faster than others. And spreading of HIV is possible during this phase. In the middle and end of this stage, the viral level begins to rise and your CD4 cell count begins to drop. As this happens, symptoms of the diseases begin to occur as the virus levels increase in your body.

AIDS: As the number of your CD4 cells begins to fall below 200 cells per cubic millimetre of blood, you will be diagnosed as having AIDS. (Normal CD4 counts are between 500 and 1,600 cells/mm3.)
