[Public health impact of adsorption of enteroviruses on ocean and river sediments].
Fixation of enteroviruses in sands, ocean sediments, and river mud constitutes a very real public health risk. The authors review the physicochemical and biological mechanisms of virus attachment to particles. Rates of adherence frequently reach 90 to 100%, especially in montmorillonites and sands. Studies devoted to microorganism adherence are mentioned. Attachment of enteroviruses to particles in suspension, to bacteria and other microorganisms--all becoming vectors--is described. Also reviewed is the manner in which these pathogenic substances are disseminated in the environment, especially at beaches, recreational areas and shellfish breeding areas. Greater vigilance to the dangers is advocated on the part of public health authorities, those responsible for environmental salubrity and for shellfish grounds.
