For 2018, 63 cases of diphtheria were reported to ECDC; 62 due to toxigenic Corynebacterium diphtheriae or C. ulcerans and one case with an unknown pathogen. The highest proportion of C. ulcerans cases was among adults 65 years and over, whereas C. diphtheriae cases were more common in younger age groups. Among the C. diphtheriae cases, 60% were reported as imported. High vaccination coverage is crucial to prevent diphtheria.
