Abstract

In order to make effective managerial decisions regarding sanitary-epidemiological and preventive measures, the environmental factors potentially affecting the ascariasis epidemic process in the Vladimir region (Russia) have been searched. The archived statistics on ascariasis incidence among the population has been analyzed concerning the state of the environment, socio-economic situation, as well as climate indicators in region. Statistical data processing and correlation and regression analysis have been performed using the STATISTICA software. The maps have been compiled and edited using ArcView 3.1 GIS and standard Paint computer programs. The study showed that climatic environmental parameters determining the possibility of ascaris developing eggs in the environment reaching the infective stage retain the leading role in ascariasis epidemiology in the Vladimir region. The regional factor influencing the epidemic process is air pollution from stationary objects. The mathematical equation was made to forecast the morbidity level in the region. The obtained data can be used for risk assessment of ascariasis infection in order to ensure biological safety in the region.
