Is the bed capture enzyme immunoassay useful for surveillance in concentrated epidemics? The case of female sex workers in Indonesia.

Although the BED capture enzyme immunoassay (BED-CEIA) tends to over-estimate HIV incidence in general population epidemics, its limitations may be less relevant to some sub-populations in concentrated epidemics. This study assesses the plausibility of BED-CEIA estimates for female sex workers (FSWs) in Indonesia. Data were derived from a cross-sectional anonymous linked behavioral and biological surveillance survey.

Syphilis among female sex workers in Indonesia: need and opportunity for intervention.
