Epidemiological profile and tendency of leprosy in people younger than 15 years

Objective: To evaluate the epidemiological characteristics and tendency of new leprosy cases in people younger than 15 years in the state of Bahia, Brazil, between 2007 and 2017. Method: Quantitative, cross-sectional, descriptive study of cases registered in the Notifiable Diseases Information System. The sociodemographic variables were statistically analyzed through the G-test and trend classification was analyzed through linear regression, along with the tendency or percentage change. Results: The study comprised 2,298 new cases and presented decreasing rate of detection, growing proportion of investigated contacts, and decreasing proportion of healing. Paucibacillary cases are emphasized, with a 63.27% proportion and predominance among females with incomplete primary education and brown race/color living in urban zones. Regarding clinical forms, physical disabilities, and modes of detection, 26.68% were tuberculoid, 73.72% were grade zero, and 36.42% were referral, respectively. Conclusion: The increased tendency in the proportion of investigated contacts and the decrease in the proportion of healing revealed a need for the health system to improve patient follow-up during treatment against leprosy.
