The main reservoir of intestinal viruses in the environment is human feces and contaminated wastewater. Sewage contamination preconditions further contamination of surface water serving as a source of water supply [2,7,8]. High resistance to physical and biological exposures ensures long-term survival of the viruses in water with various type and level of contaminants, especially in sewage. Detection of enteroviruses of a specific serotype in sewage indicates a significant number of people releasing the virus with feces [1,2]. There are two peaks of enteroviruses concentration in sewage: in January-April, and in June-September [8]. Sewage testing for enteroviruses is one of effective methods for their detection and risk assessment [3]. European region, including Ukraine, is recognized as free from of wild polioviruses, and a systematic study of sewage samples is important for identifying the possibilities of their "silent" circulation [6].
Objective: The purpose of the study was to confirm the hypothesis of possible intestinal viruses circulation in wastewater in Dnipropetrovsk Oblast, Ukraine.
