This is consistent with findings from a multi-country study that found a 12% TB prevalence among PLHIV not on ART in four countries in sub-Saharan Africa [10]; the TB prevalence is lower than the 15% TB prevalence among PLHIV in three countries in Southeast Asia in the ID-TB/HIV study, but this may also be related to the lower initial median CD4+ cell count in that study (242 cells/ μL) [12]. The gene discussed is CD4; the disease is tuberculosis.
