Abstract: Visceral leishmaniasis (VL) is a zoonosis found worldwide. Its incidence has increased in Brazil in recent years, representing a serious public and animal health problem. The strategies applied in Brazil are questionable and are not sufficient to control the disease. Thus, we have compared the efficacy of some of the currently available strategies focused on dogs to prevent and control zoonotic VL in endemic areas by optimizing a mathematical model. The simulations showed that the elimination of seropositive d… Show more

“…Modelling transmission dynamics has been used to predict the impact of control measures on a number of diseases, including leishmaniasis. For example, mathematical modelling was use comparing insecticide‐impregnated collars with dog culling in preventing ZVL transmission . Mathematical models were also used in anthropogenic VL transmission estimating the effect of different interventions , or in malaria control for predicting the impact of adding ivermectin to a mass treatment intervention .…”

“…Ultimately, VL being a vector-borne disease means that infection events are driven by sand fly 296 biting behaviour and sand fly interactions with hosts. Accordingly, finding greater sensitivity 297 on infection prevalence when altering the parameters related to sand fly dynamics versus the 298 majority of parameters conditioned solely on dogs is not unexpected and is in agreement with 299 prior studies displaying the sensitivity of Leishmania transmission models to sand fly parameter 300 values [13,38]. Furthermore, the importance of understanding sand fly biology and biting be-301 haviours in relation to transmission probability and control has been underpinned by laboratory 302 experiments and observations in nature [32,[39][40][41][42].…”

“…Moreover, when comparing the respective sensitivity test values in three other sand fly-associated 230 parameter sets, sand fly bite rate (parameter ID 11), probability of a susceptible dog becoming 231 infected when bitten by an infected sand fly (parameter ID 13) and proportion of female sand flies 232 unobserved (parameter ID 15), in each case we found the median average infection prevalence 233 to differ by over 10% across the range of values tested ( Figure 6, panels (11,13,15)).…”

“…More recently, Sevá et al [57] developed a mathematical model for human and canine zoonotic VL in Brazil. The focus of this study was to test the efficacy of existing canine-based VL prevention and control methods: insecticide-impregnated dog collars, culling, and vaccination.…”
