PREVENTION OF ACUTE INTESTINAL INFECTIONS

Abstract

Acute intestinal infections – commonly manifesting as acute gastroenteritis with diarrhea and vomiting – remain a significant global public health challenge. These infections are caused by a variety of pathogens (viruses, bacteria, parasites) and disproportionately affect young children and vulnerable populations. Worldwide, they contribute to high morbidity and are among the leading causes of mortality in children under five. Transmission occurs via the fecal-oral route, often through contaminated water, food, or person-to-person spread. Notable outbreaks in recent years (such as large cholera epidemics) underscore the ongoing threat in both developing and developed regions. Effective prevention requires a multifaceted strategy. Key measures include ensuring access to safe drinking water, improving sanitation, promoting hand hygiene and food safety practices, and deploying vaccines (like rotavirus and cholera vaccines) where appropriate. Public health interventions – from community education to robust surveillance and outbreak response – are crucial to reduce the incidence of acute intestinal infections. This article reviews the epidemiology and transmission of these infections, examines recent outbreaks, and highlights evidence-based preventive strategies that can substantially reduce the burden of acute intestinal infections globally.
