Infectious diseases represent the outcome of the parasitic interactions between biological species. The mode of transmission of the parasite microorganism to the human hosts represents the mechanisms of infection spreading. Present-day humans have inherited the infectious diseases from their humanoid ancestors. In the course of humanization, pathogenic microorganisms have evolved for invasion of the human species. Hence the mechanism of infection transmission is as well a product of the evolutionary interactions between microbes and men. One basic biological character of Homo sapiens is the acquisition of qualities that are missing in animals – consciousness and the capacity to develop a society. The social, intended actions of humans influence the mechanisms of infection transmission in parallel with the biological evolutionary factors and the environmental factors. The biological sense of the infection transmission is the survival in time of the species of pathogenic microorganisms. Dependent on the different characteristics and requirements of the pathogenic microorganisms and the human behavior, different transmission mechanisms are settled. Here we discuss the variety of mechanisms of infection transmission and their evolution under the influence of natural and social factors, as a response to the basic requirement of the species – its survival of the species.
