The Emergence of New Rotavirus Strains in America

Rotavirus infections are the most common causes of infectious diarrhea in young children and animal worldwide. In some countries in Latin American specifically in Central American and Caribbean countries, rotavirus infections are not subject to specific surveillance. This review is about the unusually strains detected and potential zoonotic of rotavirus in Latin American. Although, interspecies transmission has not been documented to occur directly, an increase of the number of reports of atypical rotavirus genotypes; apparently derived from transmission between animal of farm, domestic and wild with humans, has been reported in some Latin American countries and the world. We consider that the rapid increase in the detection of new unusual strains with genetic heterogeneity, raises interesting questions about the evolution of rotavirus in The Latin American region. The emergence of novel strains derived from interspecies transmission has implications for the design and implementation of successful human rotavirus vaccine strategies.
