Surveillance of rotavirus infections remains critical because vaccines are underutilized in the USA. Using wastewater solids measurements of rotavirus RNA collected over one year from 185 wastewater treatment plants (WWTPs) in the USA, we inferred spatiotemporal occurrence patterns of rotavirus infections and compared occurrence patterns to clinical metrics of infections and markers of vaccination coverage. We also estimated infection prevalence from wastewater measurements using available data on rotavirus RNA shedding in feces. Nationally, wastewater measurements of rotavirus RNA were correlated with clinical metrics of infection and exhibited elevated winter-spring concentrations beginning in the South. WWTP service areas characterized by markers of high vaccination coverage generally experienced a shorter duration of elevated rotavirus concentrations compared to areas characterized by markers of low vaccination coverage. Rotavirus infection prevalence estimates were highly uncertain and sensitive to shedding parameters. Wastewater monitoring of vaccine-preventable diseases is valuable for informing where vaccination campaigns should be targeted.
