Human cosavirus (HCoSV) is a novel member of the family Picornaviridae. We investigated the prevalence and genetic diversity of HCoSV in influent and effluent wastewater in Arizona over a 12-month period, from August 2011 to July 2012. HCoSV sequences were identified in six (25 %) influent samples and one (4 %) effluent sample, with the highest concentration of 3.24 x 10(5) and 1.54 x 10(3) copies/liter in influent and effluent, respectively. The strains were characterized based on their 5' untranslated region and classified into species A and D, demonstrating that genetically heterogeneous HCoSV were circulating with a clear temporal shift of predominant strains in the study area.
