Most HIV-negative adults have between 500 and 1500 CD4 cells in a cubic millimeter of blood. Most people with HIV who have an undetectable viral load can reach the normal range and often it is only a matter of time.
If you are living with HIV, a CD4 count above 350 can significantly improve health-related outcomes. People with a CD4 count below 200 are considered to have AIDS and are more susceptible to opportunistic infections. In general, higher CD4 counts offer better protection and hint at a more robust immune system.
The HIV medications neutralise the virus and protect its favourite target – the CD4 cells. Some people’s CD4 count may recover at a slower rate than other people’s, particularly in those who start treatment with very few CD4 cells. However, if their viral load is undetectable, they are better protected against opportunistic infections and other health problems than someone with an uncontrolled viral load.
