Water-borne enteric viruses pose a threat to both human and animal life causing a wide range of illnesses. Groundwater is the commonest transmission route for these viruses. About 50% of groundwater related disease outbreaks are attributable to viruses. Recent studies in developed countries have focused on public water systems, unfortunately, without much attention to private household wells and storage facilities. This paper reviews disease outbreaks attributed to water-borne viruses, the public health significance of enteric viral diseases and problems encountered in the development of diagnostic assays. The objective of this review is to confer the rationale for more research to provide reliable baseline information on the significance of water-borne viruses in the developing world. Since the virological quality of drinking water can no longer be compromised, rapid and sensitive methods for detecting enteric viruses in drinking water, recreational water and their sources is a necessity. As a preventive measure, ground, surface and treated drinking water must be protected from viral contamination. Enforcement of legislative measures for regular viral monitoring of drinking water in the industry will ensure safety of consumers.
