Rotavirus particles remain active on human hands for at least 4 hours, on hard dry surfaces for 10 days, and on wet areas for weeks.
There is a fairly rapid test for rotavirus diarrhea. The direct-antigen test can give results in 24 hours.

The virus does not remain in the body after the infection has resolved, and there is no carrier state (i.e., a person who spreads the disease to others but does not become ill).

The virus may also spread among young children in day care settings.
