Complete Genome of the Human Norovirus GIV.1 Strain Lake Macquarie Virus

Norovirus is an important human pathogen that is now recognized as the leading cause of acute gastroenteritis globally. Six viral genogroups have been described, although only genogroups GI, GII, and GIV are known to infect humans, with the GII viruses most commonly identified in both outbreak and sporadic settings. In contrast, infections by GIV viruses are rarely reported, and their overall prevalence in the community is unknown. Here, we report the complete genome sequence of the human GIV.1 strain Lake Macquarie virus, which caused two linked outbreaks of acute gastroenteritis in aged-care facilities in the Hunter region of New South Wales, Australia. The Lake Macquarie virus genome was 7,527 nucleotides (nt) in length and shared highest identity (70%) with the recently completed feline GIV.2 virus genome.
