For 2017, 39 cases of diphtheria due to toxigenic Corynebacterium diphtheriae or C. ulcerans were reported to ECDC. The highest proportion of C. ulcerans cases was among adults 45 years of age and above, whereas C. diphtheriae cases were more common in younger age groups. Among C. diphtheriae cases, 50% were reported as imported. High vaccination coverage is crucial to prevent diphtheria.
