Warning over imminent Australian norovirus epidemic

Widespread outbreaks of norovirus gastroenteritis are likely to occur in the near future due to a new mutation of the highly infectious pathogen, virologists say.

Researchers at the Victorian Infectious Diseases Reference Laboratory say they have identified early outbreaks with a novel recombinant strain of norovirus known as GII.4 New Orleans 2009/Sydney 2012.

The new recombinant strain was first detected in Victoria in August 2015 then re-emerged, with genetic changes, in June 2016 and has been the causative agent in the majority of norovirus gastroenteritis
