Description
Objective: Antenatal clinic (ANC)-based surveillance through unlinked anonymous testing (UAT) for HIV without informed consent provides solid long-term trend data in resource-constrained countries with generalized epidemics. The rapid expansion of the prevention of mother-to-child transmission (PMTCT) and voluntary counseling and testing (VCT) programmes prompts the question regarding their utility for HIV surveillance and their potential to replace UAT-based ANC surveillance. Methods: Four presentations on the use of PMTCT or VCT data for HIV surveillance were presented at a recent international conference. The main findings are presented in this paper, and the operational and epidemiological aspects of using PMTCT or VCT data for surveillance are considered. Results: VCT data in Uganda confirm the falling trend in HIV prevalence observed in ANC surveillance. Thailand, a country with nationwide PMTCT coverage and a very high acceptance of HIV testing, has replaced UAT data in favor of PMTCT data for surveillance. Studies from Botswana and Kenya showed that PMTCT-based HIV prevalences was similar, but the quality and availability of the PMTCT data varied. Conclusion: The strength of UAT lies in the absence of selection bias and the availability of individual data. Conversely, the quantity of VCT and PMTCT programme testing data often exceed those in UAT, but may be subject to bias due to self-selection or test refusal. When using VCT or PMTCT data for surveillance, investigators must consider these caveats, as well as their varying data quality, accessibility, and availability of individual records. © 2005 Lippincott Williams & Wilkins.
