Abstract Background Enteroviruses can shed in feces for several weeks so many excrete viruses can remain infectious for a long time in environment. Therefore by detecting enteroviruses in environmental specimens and sewage we can understand this virus circulation the approximate ratio of contaminated persons in society and they are suitable indicators for environmental surveillance. Methods Since March 2006 to February 2007 86 specimens from Sistan Balouchestan 63 specimens from Tehran and 48 samples from Fars sewage disposal systems and surface water were collected by Grab Sample method and tested for enteroviruses directly by using two concentration methods Pellet and Two-phase. Then Non-Polio Enteroviruses NPEV were serotyped by microneutralization method. Results Enteroviruses were isolated from 49 56.98 of specimens in Sistan Baluchestan 38 60.32 in Tehran and 11 22.92 in Fars. Besides the majority of Non-Polio Enteroviruses related to Non-typable Enteroviruses
