Norovirus GI/II

Norovirus GI/II refers to norovirus genogroups I and II, which are viruses linked to the gastrointestinal tract and can be detected in stool. These viruses are not considered a normal part of the dog’s gut microbiome. A finding may reflect exposure through water, food, surfaces, or shared environments that have been contaminated with faeces. Norovirus is mainly linked to the stomach and intestines, where it may be associated with diarrhoea, vomiting, altered stool quality, reduced appetite, low energy, or signs of gut irritation. Because Norovirus GI/II is primarily known in relation to human gastroenteritis, a finding in a dog sample should be interpreted carefully. A positive finding may be useful to review with a veterinarian, especially if digestive signs are present or if there are hygiene concerns in a shared environment.
