What is the epidemiological cycle of visceral leishmaniasis in Brazil?


A) Rural cycle: (1) affected fox; (2) infected opossum (sinanthropic reservoir that circulates in wild, rural, and urban environments); (3) chicken coop where flebotomos (Lutzomyia longipalpis) reproduce; (4) infected hunting dog (domestic reservoir); (5) L. longipalpis infected; (6) rural domicile where infected flebotomos in reservoirs bite humans. B) Urban cycle: (a) infected domestic dog; (b) infected opossum; (c) chicken coop in backyard; (d) L. longipalpis infected; (e) urban domicile where infected flebotomos in reservoirs bite humans. The arrows indicate the possibilities of parasite circulation.
B) Urban cycle: (1) infected domestic dog; (2) infected opossum; (3) chicken coop in backyard; (4) L. longipalpis infected; (5) urban domicile where infected flebotomos in reservoirs bite humans. The arrows indicate the possibilities of parasite circulation.

A alternativa correta é a A) Ciclo rural: (1) raposa afetada; (2) gambá infectado (reservatório sinantrópico que circula em ambientes selvagens, rurais e urbanos); (3) galinheiro onde flebotomos (Lutzomyia longipalpis) se reproduzem; (4) cão de caça infectado (reservatório doméstico); (5) L. longipalpis infectado; (6) domicílio rural onde flebotomos infectados em reservatórios picam humanos. As flebotomias infectadas em reservatórios são responsáveis pela transmissão da leishmaniose visceral no Brasil.
