Non-seasonal distribution of rotavirus in Barcelona raw sewage.

To ascertain the occurrence of a seasonal distribution of human rotavirus in Barcelona raw sewage, surveys of rotavirus levels in wastewater were undertaken in November 1985 and July 1986. A uniform distribution of rotaviruses was found to occur, which is consistent with the reported local frequencies of rotaviral diarrhoea, in contrast with the strict seasonability observed for rotavirus infections in temperate climates.
