Pilot study to assess the impact of feed-through insecticide on the sand fly density in an endemic area of zoonotic cutaneous leishmaniasis in Morocco

This study assessing the impact of feed-through insecticide on sand fly density and Leishmania infection rates in an endemic ZCL area in Morocco found insufficient evidence of impact on sand fly densities to achieve epidemiological relevance. Additionally, the study revealed gaps in the understanding of the transmission cycle, as two Leishmania species other than L. major were identified as potential causes of CL in the area. These findings underscore the need for improved knowledge of the transmission dynamics to enhance control measures.
