Pets and avoiding spreading sickness

[projekktor id=’18577′]

An article published today in the Canadian Medical Association Journal cautions that people with compromised immune systems can get infections from their animals. Zoonoses are diseases that spread from animals to humans and people with weakened immune systems are at higher risk. That doesn’t mean they can’t own pets, they just have to take extra precautions.

Infectious disease specialist, Dr. Martha Fulford says people with weakened immune systems need to be cautious because it’s harder for their bodies to fight off infections. That includes young children, pregnant women, older adults and people on chemotherapy and immune supressing drugs.

Salmonella and other diarrhea causing bacteria are most common, and can get into your blood. “If it’s in your blood you’re much more likely to be extremely sick and require hospitalization. It potentially can kill you.” says Dr. Fulford.

Reptiles and amphibians pose the highest threat and their food can also be a source of infection. Puppies and kittens are also riskier because they shed more bacteria and are more likely to nip or scratch. Fulford says that these aren’t reasons not to own a pet though; the benefits outweigh the risks.

To avoid infection: keep litter boxes away from food, avoid sharing a bed or letting your pet lick your face and wash your hands after petting them.
