Seasonal distribution of enteroviruses and adenoviruses in domestic sewage

Abstract
A seasonal distribution of enteroviruses and adenoviruses in raw sewage effluents of Athens, Greece, was observed over a 15-mo. surveillance period. All 36 samples tested were positive for both virus groups. Adenovirus concentration levels ranged from 70-3200 cytopathic U/l of sample, whereas the corresponding values for enteroviruses were 90-900 cytopathic U/l. Peak values for adenoviruses were recorded during the months of April and June 1983, whereas for enteroviruses the peak was recorded in Sept. 1983. All three types of poliovirus were present. Coxsackievirus types B-1, B-2, B-4 and B-5 and echovirus type 7 were also isolated. Adenovirus types 1, 2, 3, 5, 7 and 15 were also detected.
