This regional survey report presents findings from qualitative and quantitative surveys among migrants in the South Caucasus countries of Armenia, Azerbaijan, and Georgia. The objective of the qualitative survey was to assess experiences with and access to public health-care services related to HIV and tuberculosis (TB) in migrants’ own countries and abroad. Specific goals were to clarify barriers in availability, accessibility, acceptability, and quality (AAAQ) of TB and HIV health services for migrants within the countries of origin and destination, as well as collect recommendations and opinions for improving AAAQ of TB and HIV health services for migrants. The objective of the quantitative surveys was to measure HIV prevalence and TB signs and symptoms among migrant populations. Other goals were to determine the study participants’ migration experiences, living and working conditions, sexual behavior, and HIV testing and TB screening history in their own country and abroad. This evidence will help to ensure the development of adequate migrant-inclusive policies and public health interventions, especially related to TB and HIV.
