Reverse zoonosis: Can you make your pet sick?

Reverse zoonosis: Can you make your pet sick? Swine and bird flu are two of the most recent and startling examples of animals passing diseases to humans.

Other unpleasant pet-to-human medical problems include ringworm, roundworm, and hookworm, as well as beaver fever, toxoplasmosis, and rabies.

 Although these animal-to-human transmissions are relatively well described, pathogenic traffic in the opposite direction is much less well understood.

 Reverse zoonosis is not just an interesting concept; it is an important global issue. Animals bred for food are transported far and wide, interacting with wild species that they would never naturally have encountered.

With a rapid growth in animal production and an increase in the movement of both animals and people, a human pathogen within an animal could potentially move thousands of miles in just 24 hours.

 For instance, during the H1N1 influenza pandemic of 2009, the virus was able to travel the breadth of the planet and from pigs to humans in a matter of months.
