(A) Monthly orthohantavirus prevalence rates among patients seeking medical attention in Barbados, 2008 to 2016. (B) Comparison of mean orthohantavirus prevalence rates related to season, gender and location among patients seeking medical attention in Barbados, 2008 to 2016. Wet season in Barbados includes the months of June to November and the dry season December to May. Rural parishes include St. Lucy, St. Peter, St. John, St. Thomas, St. George, St. Andrew and St. Joseph and urban parishes include St. Michael, Christ Church, St. James and St. Philip. Statistically significant differences were observed with orthohantavirus prevalence rates between wet seasons vs. dry seasons, females vs. males, and between patients living in urban vs. rural parishes. The 95% confidence intervals (CI) were calculated to determine level of significance of the differences in orthohantavirus prevalence rates.
