In Brazil, an increase has been recorded in recent years in the magnitude of detection coefficients for new cases of Hansen's disease, which is frequently interpreted as evidence of the endemic's expansion. The objective of this work is the determine the role of operational factors for interpreting the trend displayed by the morbidity coefficients for Hansen's disease from 1982 to 1995 in the country. We observed a strong correlation between the adjusted detection coefficients and the number of technicians trained (r = 0.80), a decrease in the proportion of new cases with disabilities at the time of diagnosis (r = 0.86), and a downward trend in tuberculoid forms (r = -0.70). Patient time on the active register is correlated negatively with MDT-WHO coverage (r = -0.95) and the percentage of patients discharged from treatment due to cure (r = -0.91). These results suggest that the increase in the potential for detection of new cases of Hansen's disease resulting from new strategies adopted by the program, i.e., mainly extensive training of health personnel, could be a coherent explanation for the increase in detection coefficients for new cases observed in Brazil in the last ten years.
