Characterization of a municipality as free of canine visceral leishmaniasis in the context of One Health

Abstract Dogs are the main urban reservoir of Leishmania infantum, the causative agent of visceral leishmaniasis (VL), which is transmitted by sand flies. In the state of Paraná, the first detection of a positive dog for VL was in 2014, this year Paraná lost free status for this disease (VL). The ob...

Zusammenfassung:Abstract Dogs are the main urban reservoir of Leishmania infantum, the causative agent of visceral leishmaniasis (VL), which is transmitted by sand flies. In the state of Paraná, the first detection of a positive dog for VL was in 2014, this year Paraná lost free status for this disease (VL). The objectives of this study were to determine the prevalence of canine visceral leishmaniasis in Palotina, the occurrence of vectors that may transmit Leishmania infantum, and the number of notifications of human visceral leishmaniasis cases from period 2010 to 2020. To determine the occurrence of canine visceral leishmaniasis, blood samples from 204 dogs were analyzed using the rapid test DPP® to detect anti-L. infantum antibodies. To investigate the occurrence of potential vectors, monthly collections were made at 18 points within the urban area of the municipality. The number of human visceral leishmaniasis cases was investigated from Epidemiological Surveillance records. None of the serologically tested dogs showed positive titration. Only two specimens of Lutzomyia neivai, one of Lutzomyia sp. and four of Brumptomyia brumpti specimens were collected. No human visceral leishmaniasis cases were reported. These results suggest that there is no evidence of circulation of L. infantum in Palotina. Resumo Os cães são os principais reservatórios urbanos da Leishmania infantum, agente causador da leishmaniose visceral (VL), transmitida por vetores conhecidos como flebotomíneos. No Paraná, a primeira detecção de casos positivos caninos ocorreu em 2014, ano em que o Paraná perdeu o status de estado indene. O objetivo deste estudo foi determinar a prevalência da leishmaniose visceral canina no município de Palotina, a ocorrência de vetores que possam transmitir Leishmania infantum e o número de notificação de casos de leishmaniose visceral humana, no período de 2010 a 2020. Para determinar a ocorrência da leishmaniose visceral canina, amostras de sangue de 204 cães foram analisadas, utilizando-se o teste rápido (DPP®) para detectar anticorpos anti-L. infantum. Com o objetivo de investigar a ocorrência de potenciais vetores, coletas foram realizadas mensalmente em 18 pontos na área urbana do município. O número de casos de leishmaniose visceral humana foi investigado a partir de registros da Vigilância Epidemiológica. Nenhum cão testado foi positivo no teste sorológico. Apenas dois espécimes de Lutzomyia neivai, uma de Lutzomyia sp. e quatro de Brumptomyia brumpti foram cole
