Detection of wild-type rotavirus by nucleic acid testing.
Rotavirus infection is notified by laboratories on microbiological confirmation (ideal reporting by routine mail).
Both confirmed and probable cases should be entered onto the Notifiable Conditions Information Management System (NCIMS).
Rotavirus is a virus in the Reoviridae family. Group A is common in humans; group B in uncommon in humans but has caused large outbreaks in China.
Primarily faecal oral contact and respiratory spread may be possible.
The typical incubation period is approximately 24 to 72 hours.
Rotavirus is infectious for the duration of the acute stage of illness and later while the virus shedding continues. This usually lasts from 4 to 8 days but can be up to 30 days after onset of illness.
Rotavirus can present as a range of illnesses from mild, watery diarrhoea of limited duration to severe, dehydrating diarrhoea with vomiting, fever, and shock. Symptoms generally resolve in 3 to 7 days.
Within 3 working days of notification enter confirmed and probable cases on NCIMS.
For notified cases with a date of birth after 1 May 2007, ascertain their vaccination status from ACIR and include in NCIMS.
None routinely. When a cluster is reported in an institutional setting follow the Gastroenteritis in an Institution response protocol.
