[Surveillance of enteroviruses in the waste water of the Ivory Coast].

Viral water contamination is on the increase all over the world and one is concerned by the dangers to which it exposes health and preoccupied with the search for effective solutions. This study, which was conducted in a year in Côte-d'Ivoire, enabled us to examine the degree of viral pollution from waste water collected from a lagune. It allowed us to follow the distribution of enteroviruses and their fluctuations during the year. 164 waste water samples were tested and 93 enterovirus strains isolated. 67.89% showed polioviruses and 32.11% coxsackieviruses. Seasonal fluctuations of the virus concentration in the lagune water were shown from statistical analysis of the data collected. Concentration was high during the rainy season and definitely lower during the dry season with the rise in water temperature.
