“…Verifica-se, na figura 2 , a existência de um cluster de casos de hanseníase, detectado em fase anterior ao estudo ( 6 ). Do total de soropositivos (n = 421), 353 (83,8%) residiam fora do cluster de casos, demonstrando, com significância estatística ( P < 0,001), maior soropositividade nos setores censitários que correspondem ao bairro Palha, local com o maior número de escolares com sorologia anti-PGL-I positiva.…”

“…Como público-alvo para cada fase de coleta de dados, foram selecionados: 1) casos de hanseníase e seus contatos; 2) escolares de 7 a 14 anos do município; e 3) familiares e vizinhos dos escolares soropositivos e vizinhos de casos de hanseníase. Foram incluídos familiares que residiam no mesmo domicílio e vizinhos de 32 escolares que apresentaram sorologia positiva anti-PGL-I na fase anterior da pesquisa ( 6 ), bem como vizinhos de 13 casos de hanseníase multibacilar que moravam há mais de 5 anos no mesmo domicílio. Considerou-se como vizinho todo indivíduo que residia em um raio de até 100 metros de distância da residência dos escolares soropositivos e dos casos de hanseníase, com mais de 5 anos de idade e sem histórico de hanseníase.…”

“…1,4 It is pointed out that, in recent years, there is a recommendation on the follow-up of extradomiciliary contacts of leprosy, which is seen by several authors as an enhancement in the control of the disease, especially those who defend the stone in the pond model, in order to extend control beyond the family circle, involving neighbors, people from the work circle, church, among other collective spaces. 1, [4][5][6] In 2017, the Ministry of Health published a new classification and concepts of contact -home and social, with home contact "any person residing or residing with the leprosy patient" and social contact as " any person who lives or has lived in family relationships or not, in a close and prolonged way". 4:8 It is also stated in this document that recent or old family contacts, of any clinical form, should be examined independently of the length of contact, and it is suggested to evaluate them annually for five years, whether they are family contacts and, after this period, should be released and advised about the possibility in the future of the appearance of signs and symptoms suggestive of leprosy.…”

“…It is also pointed out in studies carried out in various scenarios and methodologies, a higher risk of getting sick from these household contacts of leprosy. [6][7][8] It is warned that the risk of the disease is higher in the first year after the diagnosis of the index patient and that, if the patient is treated, the likelihood of disease between home contacts tends to fall, although secondary cases may arise due to the long incubation period of the agent or over long exposure to the bacillus. 9 Afirma-se, ainda, que "é importante ter em mente que um indivíduo pode estar infectado, mas não mostrar sinais da doença".…”
