Abstract
INTRODUCTION Intra-domiciliary contacts are a group with the highest risk of developing leprosy.METHODS A cross-sectional study of intra-domiciliary contacts of new leprosy cases was conducted. A descriptive analysis of the variables was performed. RESULTS Among 190 contacts, 63% were invited to visit the health unit, and 54.2% received the BCG vaccine. The prevalence of leprosy among the contacts was 4.7%. CONCLUSIONS The occurrence of leprosy among the contacts was high and similar to that found previously. There were failures in surveillance actions carried out by health units. Never-before treated cases were found.

Introduction: Intra-domiciliary contacts are a group with the highest risk of developing leprosy
Half of the contacts in the present study who developed the disease were diagnosed before the index case, suggesting that they constituted the true primary cases in the domiciliary epidemiological chain
More than 85% of the index cases and 87.5% of the contacts received the diagnosis at the reference service
