Environmental Health and Child Survival

Interest in environmental health has increased in recent years, largely because the most vulnerable groups remain disproportionately exposed to and affected by health risks from environmental hazards. More than 40 percent of the global burden of disease attributed to environmental factors falls on children below five years of age, who account for about 10 percent of the world's population. Children are especially susceptible to environmental factors that put them at risk of developing illness early in life. Malnutrition is an important contributor to child mortality; malnutrition and environmental infections are inextricably linked, but these links have been forgotten or neglected by policy-makers. The World Health Organization (WHO) recently convened an expert panel, which concluded that about 50 percent of the consequences of malnutrition are in fact caused by inadequate water and sanitation provision and poor hygienic practices. Recent recognition of environmental linkages with malnutrition highlights the urgent need to develop a spectrum of interventions to reduce exposure to environmental risks.
