Explore the recorded discovery and history of Rotaviruses, with source links and stated limits.
CDC describes rotavirus as a common cause of severe watery diarrhoea and vomiting, especially in children, with no specific medicine to treat the infection itself. Children can become dehydrated, need hospital care and, in the worst cases, die. Rotavirus vaccination is the main protection, and this profile covers human rotaviruses as a group rather than a single strain.
CDC's Pink Book records that in 1973 Ruth Bishop and colleagues observed a virus particle in the intestinal tissue of children with diarrhoea using electron microscopy. It was later called rotavirus because it looked like a wheel; rota is Latin for wheel.
By 1980 rotavirus was recognised as the most common cause of severe gastroenteritis in infants and young children in the United States. Until the early 1970s a cause could be identified in fewer than 30% of childhood diarrhoea cases.
A rotavirus vaccine was first licensed in the United States in 1998 and withdrawn in 1999 after an association with intussusception. Second-generation vaccines were licensed in 2006 and 2008.
Diarrhoeal disease has been recognised since antiquity, and the 1973 milestone records identification of the virus in tissue samples rather than a first patient. No origin country or patient zero follows from these records.
