∗Seroprevalence was measured by ELISA at 0.189 cut-off level. ∗∗Missing data were excluded. #Working definitions: lesions on the skin accompanied by the disintegration of tissue or not were considered as ulcerative (viz., ulcerating nodules, ulcerating plaques, and complete ulcers) and nonulcerative (viz., papules, nodules, and plaques) lesions, respectively.
