Estimating the Optimal Control of Zoonotic Visceral Leishmaniasis by the Use of a Mathematical Model

الملخص EN

We argue that the strategy of culling infected dogs is not the most efficient way to control zoonotic visceral leishmaniasis (ZVL) and that, in the presence of alternative control strategies with better potential results, official programs of compulsory culling adopted by some countries are inefficient and unethical.

We base our arguments on a mathematical model for the study of control strategies against ZVL, which allows the comparison of the efficacies of 5, alternative strategies.

We demonstrate that the culling program, previously questioned on both theoretical and practical grounds is the less effective control strategy.

In addition, we show that vector control and the use of insecticide-impregnated dog collars are, by far, more efficient at reducing the prevalence of ZVL in humans.
