Zooprophylaxis is a vector-borne disease control strategy that involves diverting disease-transmitting vectors (usually mosquitoes) from humans to alternative animal hosts. The principle is to place livestock or other animals, which are not susceptible to the human pathogen or are 'dead-end' hosts, between the vector population and the human population. The vectors feed on these animals instead of humans, thereby reducing human-vector contact and the transmission of the pathogen. An example related to malaria control is the use of cattle in areas where the primary malaria vector, Anopheles mosquitoes, is zoophilic (prefers to feed on animals). By keeping cattle near human dwellings, the mosquitoes may preferentially feed on the cattle rather than humans. Since the malaria parasite (Plasmodium) does not develop in cattle, the infectious cycle is interrupted. This can reduce the entomological inoculation rate (EIR) and lower malaria incidence. However, its effectiveness depends on the specific feeding preferences (anthropophilic vs. zoophilic) of the local mosquito species and requires careful implementation to avoid creating new problems.
