Global challenges in acute diarrhea

Purpose of reviewChildhood diarrhea is the most common cause of morbidity and mortality, especially in the low and middle-income countries. The burden of child mortality because of diarrhea has declined, but still a lot is desired not only to reduce diarrhea-specific mortality but reduce the overall incidence, and hence the morbidity associated with childhood diarrhea.Recent findingsA recent Lancet series on diarrhea suggests that amplification of the current interventions can eliminate virtually all preventable diarrhea deaths. A refocused attention and strategy and collective effort from the multilateral entities to promote water sanitation and hygiene, rotavirus vaccination, nutrition, and improved case management can bridge gaps and tackle the existing undue burden of deaths because of diarrhea.SummaryInvestment toward preventing and controlling childhood diarrhea should be a priority, especially when the existing solution is plausible for implementation at scale and in underprivileged settings.
