Investigation of a Large Diphtheria Outbreak and Cocirculation of <i>Corynebacterium pseudodiphtheriticum</i> Among Forcibly Displaced Myanmar Nationals, 2017–2019

Abstract

We report confirmation of a diphtheria outbreak and identification of a cocirculating Corynebacterium species. The high proportion of C. pseudodiphtheriticum codetection may explain why many suspected patients testing negative for C. diphtheriae presented with diphtheria-like symptoms.
