It has been shown that practical activity of people during the last several decades exerts significant influence not only for frequency of population's contacts with leptospirosis foci, but also for changes of mammalian types which are reservoirs and sources of infection. The last ones in significant proportion determined etiological structure of human diseases, mechanisms of infection transmission, social and professional groups, who have highest risk to be infected, and also incidence rates and changes in clinical course of infection and its outcomes. The evolution of leptospirosis is characterized by cyclic changes of epidemiological and clinical indices. (Infekci i immunitet, 2011, vol. 1, N 1, p. 67-76)
