Campylobacter infections have been associated with diarrheal disease as well as growth faltering in children. The fraction of severe diarrheal cases in infants attributed to Campylobacter jejuni or Campylobacter coli ranged from 6% in Kenya to 12% in Bangladesh in the Global Enteric Multicenter Study (Liu et al. 2016). Campylobacter is also increasingly implicated in growth faltering among children <2y of age.
