Seroprevalence of California serogroup viruses in the western Hudson Bay polar bear population during 3 periods in study of widespread exposure to mosquitoborne California serogroup viruses in caribou, Arctic fox, red fox, and polar bears, Canada*

Years Sample size Prevalence, % (95% CI) No. males Prevalence, % (no.) No. females Prevalence, % (no.)
1986–1989 142 21 (13–26) 67 18 (12) 70 23 (16)

2015–2017 100 27 (19–36) 47 17 (8) 53 36 (19)
