Review of 158 cases of blastomycosis in Quebec documented during 1998–2011. (a) Number of diagnosed cases of blastomycosis in various age groups in the province. (b) Linear regression model demonstrating the occurrence of blastomycosis in Quebec (R²=0·418, P=0·001). The slope of a trend line was calculated as 0·37 cases/year. (c) Linear regression model analysis of annual incidence of blastomycosis per 100 000 people in Quebec (R²=0·369, P=0·002). The slope of a trend line was calculated to be 0·0044 cases/100 000 individuals per year.
