Zoonosis & Human Health

  • Rabies is a viral disease that can infect all warm-blooded animals, including cats and people, although some species are somewhat naturally resistant to the disease. When signs of rabies occur, it is an almost invariably fatal disease.

  • Rabies is one of the most devastating viral diseases affecting mammals, including dogs and humans. It is a fatal disease caused by infection with the rabies virus. Rabies virus is found throughout the world, including North America, Central and South America, Asia, Africa, the Middle East, and some parts of Europe. Following a bite from a rabid animal, the disease progresses in stages. Dumb rabies is the more common form in dogs. There is progressive paralysis involving the limbs, distortion of the face and a similar difficulty in swallowing. Vaccination is the cornerstone of rabies prevention.

  • Ringworm is the common name given to a fungal infection of the superficial layers of the skin, hair, and nails. The common name of ringworm is somewhat misleading, in that it is not an infection caused by a worm, and the infected areas are not always ring-shaped. In the dog, ringworm lesions usually appear as areas of hair loss (alopecia) that are roughly circular.

  • Roundworms are one of the most common intestinal parasites of the cat. Almost all cats will become infected with roundworms at some point in their life and most often as kittens. Roundworms are not particularly harmful to adult cats, but large numbers may cause life-threatening problems in kittens and debilitated older cats.

  • H1N1 influenza virus emerged in pigs as a genetic sharing of DNA from both human and swine influenza viruses. It caused a deadly pandemic in 2009 and continues to be an important cause of illness today. Pets including cats and dogs can be infected from their owners and become ill. It is not yet thought to transfer from pets to humans. Because influenza viruses appear to be capable of swapping genes, there is potential for new variants of influenza viruses to be generated at any time leading to another pandemic of severe disease in humans and other animals. Good hygiene and exposure restriction should be taken immediately if there is any sign of influenza-like infection to restrict spread between humans and between humans and their pets or domestic animals.

  • Tapeworms are parasites that infect the gastrointestinal tract of cats, other animals, and humans. Several types of tapeworms are known to infect pets, but the most common species observed in cats is Dipylidium caninum, which is transmitted through fleas. Risk factors, clinical signs, treatment, and prevention are explained in this handout. Other, less common types of tapeworms that affect cats and humans are also covered.

  • Ticks are parasites that feed on the blood of their host and can in turn transmit diseases to your pets or even you. They are prolific breeders and their life cycles can extend through multiple seasons. Prompt removal or use of preventatives limit or prevent the spread of disease, or kill the ticks.

  • Ringworm in Dogs

    Tiña es el nombre común que se le da a una infección fúngica en las capas más superficiales de la piel, pelo y uñas. La tiña puede afectar a las personas y a todas las especies animales domésticas. En la gente infectada las lesiones presentan una lesión redonda, roja, delimitado por unos bordes elevados a causa de la inflamación.

  • **This article has been specifically written for dog walkers and how they can reduce their exposure to COVID-19.** COVID-19 is a new respiratory disease in humans, initially discovered late in 2019. Although all coronaviruses are related, they are not all the same virus; SARS-CoV-2 cannot cause canine coronavirus infection, and vice versa. As a dog walker, it is important to limit direct contact with your clients. People can shed the virus without showing any symptoms of disease, so it is important to practice physical distancing even with clients who appear healthy. It is also important to limit your contact with potentially contaminated items in your clients’ homes, whether they are at home or not. The most important things you can do to minimize your risk of infection, and minimize the risk of transferring infection to your clients, is to be cautious when interacting with clients and when touching anything that could be contaminated. Communicate with your clients regularly during this pandemic. Having information about your clients’ health can help you avoid taking unnecessary risks. Finally, if you develop any signs of COVID-19, including cough, fever, and/or shortness of breath, it is important that you stay home from work.
