Antiretroviral treatment initiation among HIV-infected pregnant women with low CD4(+) cell counts in Gaborone, Botswana.

Background: Botswana has the most comprehensive public program in Africa for providing antiretroviral therapy to treat HIV and prevent mother-to-child transmission (PMTCT). Botswana guidelines prioritize CD4(+) cell count testing during pregnancy and initiation of highly active antiretroviral treatment (HAART) for women who qualify for treatment. We analyzed rates of HIV testing, CD4 cell count testing, and HAART initiation during pregnancy.
