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.

“…Rotavirus is one of the leading causes of infectious gastroenteritis worldwide (10,11). Prior to the introduction of vaccines, it was estimated that approximately all children under the age of 5 had been infected with rotavirus; 352,000 to 592,000 children under the age of 5 are estimated to die each year from rotavirus infections, and 82% of these deaths occurred among children in low-income countries (12).…”

Rotavirus is transmitted from person to person via the fecal-oral route (11,13). It can also be transmitted through fecal-contaminated water, especially in developing countries (11,14).…”
