FSW = female sex worker, MSW = male sex workers, MSM = men who have sex with men, ANC = ante-natal clinic, STD = sexually transmitted diseases, IDU = injecting drug user, bantha = biological males with a male gender identity, khotki = biological males who dress as men but have “female soul” and feminized traits, khusra = transgenders who dress as women (also known as hijra).
Criteria used to judge the confidence in the serology measurements were the robustness of the serology test used, procedures used to conduct the serology test, and amount of available information on the serology test. We labeled any test with greater than 95% specificity and sensitivity excellent; tests with greater than 90% sensitivity and specificity good; tests with greater than 75% sensitivity and specificity fair; all other tests were considered poor. Poor tests tend to suffer from cross-reactivity with other infections, particularly HSV-1. We also judged a test to be poor if authors used or described tests that have not been validated in the medical literature. In several cases, we were not able to identify the test used from manuscripts and numerous attempts to contact authors: these were labeled unknown.
