Rotavirus is a highly contagious disease that can cause severe vomiting and diarrhoea.  It is a viral disease that spreads through the faecal-oral route, either through contact with faeces from an infected person (e.g. while changing a child’s nappy) or through contact with the clothing or bedding of an infected person.

Rotavirus (the name of the virus that causes the disease rotavirus) is a double-stranded RNA virus surrounded by a triple-layer capsid, but no envelope.
