In recent years in several regions of Russia, there is an aggravation of the epidemiological situation of arboviruses, rickettsiosis and other natural focal infections. Within the arid zone of Russia is among the most common natural focal diseases include fever, Astrakhan rickettsial fever, Crimean hemorrhagic fever, West Nile fever and others. The prevention of such diseases is one of the most important and most difficult tasks in the protection of public health. When studying features of epidemic process of these infections are detected spatial and temporal patterns that depend on changes in climatic, hydrological and other natural factors, the abundance of vectors and reservoirs of vector-borne infections and anthropogenic impact. This is confirmed by high values of correlation of morbidity rates and environmental conditions. Of the most significant factors influencing the deterioration of epidemiological situation are: the hydrometeorological characteristics of the habitat of pathogens and vectors of diseases as the warm and long summer, no extreme low air temperatures in winter and high levels of humidity of the territory in some years.

Key words: natural focal disease, the spatio-temporal patterns, damage to health, historical and geographical analysis
