Reverse zoonosis causes concern
The concept of reverse zoonosis, in which humans can pass illness on to their pets, is causing concern with the approach of the influenza (flu) season.
Many people do not realise they can not only pass flu on to other humans when they get sick, but also animals, including dogs, cats and ferrets.
Scientists and vets hope to help prevent reverse zoonosis by raising awareness of the issue.
It is well known that animals such as pigs and birds introduce new strains of flu to humans, such as the most recent H1N1 flu strain, however, it is less known that humans have further passed these on to other animals.
There is currently little known about reverse zoonosis by scientists and vets, however researchers at Oregon State University (OSU) and Iowa State University are looking at this type of disease transmission.
"We worry a lot about zoonosis, the transmission of diseases from animals to people," said Christine Loehr, an associate professor at the OSU College of Veterinary Medicine. "Any time you have infection of a virus into a new species, it's a concern, a black box of uncertainty.
"We don't know for sure what the implications might be, but we do think this deserves more attention."
Professor Loehr advises that people with flu-like symptoms distance themselves from their pets in future.
Two independent vets have launched a podcast to help owners strengthen their bond with pets. Dr Maggie Roberts and Dr Vanessa Howie, who have worked in both veterinary practice and major charities, are keen to use their experience to enable people to give pets a better life.
