In 53.2% of cases, 2 or more generations were affected, this being an outcome associated with absence of dermato-neurological examination (prevalence ratio 1.32; confidence interval [95%CI 1.10;1.59]; p-value=0.004).</p><p><b>CONCLUSION: </b>Operational failures in the surveillance of leprosy contacts in areas of high endemicity reinforce the character of institutional/programmatic vulnerability in HSN contexts with more than one case of leprosy in the three states analyzed.</p>  a2237-9622
