Epidemiology and prevention of rotavirus infection: an underestimated issue?

Rotaviruses (RVs) were found to cause human disease in 1973. They are the leading cause of severe gastroenteritis in infants and young children of <5 years of age worldwide and they are the cause of approximately half a million deaths each year. The impact of the disease on families and society (increased health care costs, lost productivity) is extremely significant and the incidence of gastroenteritis (RVGE) is similar both in industrialized and in developing countries.
