How many persons are long-term non-progressors and what does this mean?
About 1 in 100 HIV infected persons is a so-called long-term non-progressor, meaning that they have been infected for up to 20 years and still have a normal CD4 count and low viral load. Clearly the virus has caused little damage in these persons thus far, but whether these persons will be affected by the virus in the future remains uncertain.
