"Mosquitoes are not deadly," he explains. "It is the viruses and microbes they transmit that are deadly."
So although mosquitoes do not willfully harm horses (aside from getting a snack), it is still important for owners to minimize contact between mosquitoes' mouthparts and their horses.
"Mosquitoes transmit some of the deadliest and most debilitating diseases in the world, including malaria, dengue fever, and lymphatic filariasis," says Nicholas Ledesma, a DVM/PhD candidate in the field of Comparative Biomedical Sciences at Cornell University. "In addition to the human mortality and decreased quality of life they cause, mosquito-borne diseases (arboviruses) such as Eastern equine encephalitis afflict both domestic and wild animal populations."
In this article we will describe how mosquitoes transmit viral infections, identify the most important viral infections horses can acquire from these annoying arthropods, and describe methods for protecting horses from infection through vaccination and control ¬measures.
