Presentation with gastrointestinal symptoms and high case fatality associated with group W meningococcal disease (MenW) in teenagers, England, July 2015 to January 2016.

Atypical clinical presentations associated with group W meningococcal disease (MenW) are well-described and include pneumonia, septic arthritis, endocarditis and epiglottitis/supraglottitis. Following anecdotal reports of teenagers presenting with predominantly gastrointestinal symptoms, we undertook a case review of MenW cases in 15 to 19 year-olds diagnosed in England between July 2015 and January 2016. Of the 15 cases, seven presented with a short history of nausea, vomiting and diarrhoea; five of these seven cases died within 24 hours of presentation to hospital.
