All HIV-infected subjects were anti-HIV treatment naive at study entry. HIV-infected and healthy HIV negative individuals were compared using the chi-square test for categorical variables, independent -test for normally distributed continuous variables, and the Mann–Whitney test for non-normally distributed continuous variables. HIV, HIV-infected individuals. HIV negative, healthy HIV negative individuals. NS, not significant, . Fiebig stages was based on a combination of the estimated time post-infection at sampling and ancillary HIV PCR, Western blot and/or ELISA results.
