Rotavirus disease is a diarrheal disease caused by a virus called

How is rotavirus disease diagnosed?
Confirmation of a diarrheal illness such as rotavirus
requires laboratory testing
Strains of rotavirus may be further characterized by
special testing with enzyme immunoassay or
polymerase chain reaction
– Such testing is not commonly available or necessary

– Both do not protect against diarrhea caused by other agents
than rotavirus
