Kribs11University of Texas at Arlington, Department of Mathematics, Arlington, Texas 76019, USA∗mdmondal.zahid@mavs.uta.eduAbstractLeishmaniasis is a vector borne zoonosis which is classified as a neglected tropical disease. Among the threemost common forms of the disease, Visceral Leishmaniasis (VL) is the most threatening to human health,causing 20,000 to 30,000 deaths worldwide each year. Areas where VL is mostly endemic have unprotecteddogs in community and houses. The presence of dogs usually increases VL risk for humans since dogs arethe principal reservoir host for the parasite of the disease. Based on this fact, most earlier studies considerculling dogs as a control measure for the spread of VL. A more recent control measure has been the use ofdeltamethrin-impregnated dog collars (DIDCs) to protect both humans and dogs by putting DIDCs on dogsneck. The presence of dogs helps to grow the sandfly population faster by offering a more suitable blood-mealsource. On the other hand, the presence of DIDCs on dogs helps to reduce sandfly population by the lethalityof deltamethrin insecticide. This study brings an ecological perspective to this public health concern, aimingto understand the impact of an additional host (here, protected dogs) on disease risk to a primary host (here,humans). To answer this question, we compare two different settings: a community without dogs, and acommunity with dogs protected with DIDC. Our analysis shows the presence of protected dogs can reduceVL infection risk in humans. However, this disease risk reduction depends on dogs’ tolerance for sandfly bites.1
