Rotavirus is the most common cause of diarrhoeal disease among infants and young children. Nearly every child in the world is infected with rotavirus at least once by the age of five. Immunity develops with each infection, so subsequent infections are less severe and adults are rarely affected. It infects and damages the cells that line the small intestine and causes gastroenteritis, known as “stomach flu”.
Once a child is infected by the virus, there is an incubation period of about two days before symptoms appear. Human Rotavirus is a mild to severe disease with the following symptoms:
