This paper characterizes the epidemic process of leptospirosis. The current new herd infections are typified by: 1) the formation of new natural foci under anthropogenic and climatic factors; 2) the change in the biocenotic structure of natural foci; 3) the formation of natural foci of mixed infectious diseases of bacterial and virus etiology; 4) the change in the epidemic potential of natural foci; 5) synathropization of infectious diseases. Few or no registered leptospirosis cases in some silent areas are frequently attributable to poor differential, including laboratory, diagnosis. The epidemic process is characterized in terms of the active natural focus of leptospirosis in a long-term period.
