Figure. Incidence and prevalence of invasive M. chimaera cases in Switzerland since 2008. A) Yearly incidence per 1 million inhabitants according to the date of detection. B) Prevalence per 1,000 valve replacement surgeries according to the date of index sugery. Numbers of cases are projected on the left y-axis (bars); prevalence and incidence on the right y-axis (red circles). Gray bar indicates no. cases for January–August 2017. Linear regressions (red lines) were modeled for the respective window periods of interest; dotted lines indicate 95% CIs.
