Monitoring of Group A Rotavirus Strains Circulating in the Environment and Among Children with Acute Gastroenteritis

Abstract

Rotavirus A is the causative agent of 90% of acute gastroenteritis in children under 5, which kills 1 to 3 million children per year. Their strong resistance in the environment, their inter-species transmission as well as their power of genetic recombination can give rise to new reasserting that may be harmful to public health. The simultaneous search for the presence of rotavirus A in different environmental and clinical biotopes and matrices as well as the monitoring of the seasonal evolution of episodes is of major importance. At cost, genetic monitoring of rotaviruses shows a correlation between the presence of different genotypes of RVA in the environment and the rate of morbidity, Hence the need to monitor the emergence of new circulating strains with a view to integrating them into routine immunization programmes appropriate for each region in order to limit the spread of the disease.
