Abstract
Rotavirus is a leading cause of diarrhea among children but less known as a cause among adults. We describe clinical, epidemiologic, and genotype characteristics of a rotavirus outbreak among adults in King County, Washington occurring January-June 2023. Adult rotavirus incidence in 2023 was ten times higher than the same period in 2022 (5% versus 0.5% samples). Disease severity was mild. G9P[4], an uncommon, non-vaccine strain in USA, was the predominant genotype. Genotyping suggested spillover from children with subsequent spread among adults. Our study highlights benefits of routine testing and genotyping during outbreaks for surveillance, tracking, and understanding implications on vaccination.
