Background: The group A human rotavirus is the most prevalent agents causing diarrhea in children which is found in water sources including waste and treatment waters worldwide. The aim of this study was environmental surveillance of group A human Rotavirus from influent and effluent of urban and hospital sewage systems in Shiraz.
Materials and methods: In this cross-sectional study, 60 specimens from both influent and effluent system of urban and hospital sewage disposal systems of Shiraz Nemazee hospital were collected by using grab sampling method. All samples concentrated by using two concentration methods, including Pellet and Two-phase. Then Group A human rotaviruses were detected with enzyme immunoassay (EIA).
Results: 15 (25%) group A human rotaviruses were detected, of which 11 samples (73/33%) belonged to the influent part and 4 samples (26/67%) were related to the effluent. There was a significant difference between influent and effluent of systems. Also statistical significant differences were found between the distribution of rotaviruses and months of sampling.
Conclusion: This study reveals the inefficiency of refining system in attempting to complete elimination of group A human rotaviruses. |
