Title | Cohort study on canine emigration and Leishmania infection in an endemic area for American visceral leishmaniasis. Implications for the disease control. | pt_BR |

Abstract | American visceral leishmaniasis is a main public health matter in Brazil. Since dogs have
been incriminated as the main urban reservoir of AVL agent Leishmania chagasi, a cohort
study aimed at understanding the dynamics of the canine infection was carried out in
Jequie´—an endemic community in the Northeast of Brazil. The inhabited urban and
periurban areas of Jequie´ were divided into 140 clusters of 0.25 km2. All 1681 dogs domiciled
in 34 randomly selected clusters were screened for Leishmania antibodies in an enzyme-linked
immunosorbent assay. After the seropositive dogs were painlessly eliminated, a cohort of
1286 seronegative dogs was followed up for 18 months, yielding a total of 1739.7 dog-years.
The overall incidence of Leishmania infection, as assessed by the detection of Leishmania
antibodies in blood samples collected every six months, was 6.55 cases:100 dog-years (95%
confidence interval; CI 6.04–7.26). Two subsets of clusters, with 0.70 and 1.35 relative risks
of infection, were identified. The annual emigration rate was 2.26 cases:100 dog-years (95%
CI 1.86–2.66). The implications of these findings for the control of American visceral
leishmaniasis are discussed. | pt_BR |
