Rotavirus enteritis is the most common cause of severe diarrhoea among infants and young children.[1] It is caused by Rotavirus, a genus of double-stranded RNA virus in the family Reoviridae. By the age of five, nearly every child in the world has been infected with rotavirus at least once.[2] However, with each infection, immunity develops, and subsequent infections are less severe; adults are rarely affected.[3] There are five species of this virus, referred to as A, B, C, D, and E.[4] Rotavirus A, the most common, causes more than 90% of infections in humans.
