Assessment of seasonality of rotavirus PCR detection in swine from Ontario and Quebec between 2016-2020 using submissions to a diagnostic laboratory.

ABSTRACT: The goal of this study was to determine if seasonality of rotavirus A, B, and C infection is present in Ontario and Quebec swine herds by investigating submissions to a diagnostic laboratory. Samples (N = 1557) within 755 case submissions from Canadian swine herds between 2016 and 2020 were tested for rotaviruses A, B, and C using a real-time polymerase-chain reaction assay and described. Data from Ontario and Quebec were additionally analyzed using boxplots, 6-week rolling averages, time-series decomposition, and negative binomial regression models. Percentage positivity of submissions for rotaviruses A, B, and C were discovered to be highest in nursery/weaner (n = 100, 94.0%, 60.0%, 80.0%) and grower/finisher (n = 13, 84.6%, 46.2%, 61.5%) pigs and lowest in gilt/sow (n</
