Approaches for scaling up human immunodeficiency virus testing and counseling in prevention of mother-to-child human immunodeficiency virus transmission settings in resource-limited countries.

Prevention of mother-to-child human immunodeficiency virus (HIV) transmission (PMTCT) programs have nearly eliminated mother-to-child transmission of HIV in developed countries, but progress in resource-limited countries has been slow. A key factor limiting the scale-up of PMTCT programs is lack of knowledge of HIV serostatus. Increasing the availability and acceptability of HIV testing and counseling services will encourage more women to learn their status, providing a gateway to PMTCT interventions. Key factors contributing to the scale-up of testing and counseling include a policy of provider-initiated testing and counseling with right to refuse (opt-out); group pretest counseling; rapid HIV testing; innovative staffing strategies; and community and male involvement. Integration of testing and counseling within the community and all maternal and child health settings are critical for scaling-up and for linking women and their families to care and treatment services. This paper will review best practices needed for expansion of testing and counseling in PMTCT settings in resource-limited countries.
