While vaccines such as RataTeq and Rotatrix have been made available for prevention of RV infections [15, 16] , their effectiveness remains to be verified [17] . Use of a few synthetic compounds against simian RV, such as ribavirin [18] and isoprinosine [19] , and natural products against human and bovine RV [20] , such as theaflavins, has been reported. Unfortunately, these compounds are not available for human use, which necessitates alternative methods to control RV infection [21] . A promising alternative strategy to reducing the burden of diarrhoea caused by RV may lie in identifying and developing costeffective nutritional or phytomedical solutions; which can be applicable especially in children and immunocompromised persons.
