Giardiasis: Modern concepts in control and management

Abstract

Giardia is the most common enteric protozoan pathogen of humans, domestic animals and wildlife. Children are at the most risk from the clinical consequences of Giardia infection, particularly those in developing countries and living in disadvantaged community settings. Molecular epidemiological studies have helped to elucidate sources of infection and the public health significance of animal reservoirs. Although aspects of the pathogenesis of Giardia infection are now understood, we are still a long way from understanding the factors that predispose to clinical disease. Effective drugs are available to treat giardial infections but can serve only as an adjunct to traditional public health approaches in endemic settings where children are commonly infected.
