Epizootology as a separate scientific discipline is devoted to the study of natural foci of zoonotic infections, the pathogens of which constantly circulate among populations of vertebrates, mainly mammals, with the active participation (and sometimes without it) of various ectoparasites: arthropod bloodsuckers (ticks, fleas, gnats). A person who enters the wild should know what dangers await him there and how to avoid them as much as possible, how to protect himself from infection with zoonotic pathogens.
