CD4 and AIDS: This major gap can be explainedby the non-systematization of same-day blood collection for CD4 count along withother probable causes found in providers' comments such as (1) limited sensitizationfor beneficiaries and providers on the importance of efficacious ARV regimens, and(2) a client flow that continues to adjust to this relatively new intervention.Other comments of PMTCT providers suggest that stigma may prevent women fromproviding a blood sample for CD4 cell enumeration in an HIV/AIDS care and treatmentsetting.
