Concerns regarding whether dogs can contract norovirus have arisen as human cases have surged this winter in the UK. Norovirus laboratory reports for the current 2024/2025 season in England are significantly higher than the five-season average. Typically, norovirus cases increase during autumn and winter, but this year, the rise has occurred earlier than expected and is projected to continue growing. These increases coincide with notable changes in circulating norovirus genotypes.
Dr Joanna Woodnutt from ManyPets addressed these concerns, stating that there is limited evidence suggesting that dogs may contract norovirus when in close contact with infected individuals. However, such instances are relatively rare. Drawing a parallel to the low incidence of pets contracting coronavirus during the pandemic despite numerous human cases, she noted that even if dogs do catch norovirus, there is no evidence that they can transmit the virus in quantities sufficient to infect humans. Symptoms in dogs, if present, are likely to be mild.
It is imperative to recognise that dogs possess their own strains of norovirus and other viruses that can cause gastrointestinal problems. Less than 1% of dogs showing symptoms like vomiting and diarrhoea are confirmed to have norovirus, and those that do are unlikely to be infected with the variant affecting humans. Dr Woodnutt emphasised the rarity of dogs contracting human-specific norovirus, highlighting the existence of viruses that can transfer between dogs and humans, underscoring the significance of maintaining good hygiene practices, especially when dogs exhibit gastrointestinal distress.
Pet owners are advised to uphold proper hygiene, particularly in households where individuals are experiencing symptoms of norovirus. Regular hand washing and cleaning shared spaces can help mitigate any potential risks of transmission between humans and dogs. This guidance aims to reassure pet owners amidst concerns about the transmission of norovirus to their beloved companions.
Meanwhile, many people in Wales have been affected by the recent surge of norovirus cases, further emphasising the importance of understanding how the virus spreads and impacts both humans and animals. The insights provided by Dr Woodnutt shed light on the rare occurrence of dogs contracting norovirus and offer clarity on the measures pet owners can take to safeguard their furry friends.
As norovirus continues to pose health concerns during this winter season, vigilance and proactive hygiene practices remain crucial in mitigating the spread of the virus both within human populations and the potential transmission to pets like dogs. By staying informed and following recommended precautions, individuals can protect both themselves and their animal companions from the risks associated with norovirus.
