A dog may be man’s best friend. However, household pets of all types can carry diseases or parasites (an organism living inside or on another organism) that make people sick. This includes dogs, cats, birds, and reptiles. Symptoms might include fever, muscle aches, and diarrhea. The good news is that this rarely happens. Most pet-to-people diseases can be avoided by following a few common-sense rules.
Path to improved wellness
The most important rule is to avoid touching animal waste products (urine or stool). This includes objects contaminated by the waste products. For example, wash your hands after cleaning a soiled carpet (including cleaning under your fingernails) or picking up stool.
Don’t let small children play in uncovered sandboxes that might be used as litter boxes by neighborhood cats. Keep your children out of the dirt in parks that may be used by local dogs.
Another important tip is to avoid oral with your pet. Don’t share food or kiss your pet on the mouth. Pregnant women and people who have weakened immune systems should never clean out cat litter boxes or handle cat feces. They can be exposed to a disease called toxoplasmosis, which is transmitted this way. Toxoplasmosis can cause severe birth defects in an unborn child if the mother is infected during pregnancy. Anyone cleaning out a litter box should wash his or her hands thoroughly afterward.
Have your pet dewormed and vaccinated exactly the way your vet recommends. This not only keeps your pet healthy, it decreases your risk of getting parasites and diseases from your pet. Also, control fleas and ticks on your pets and in your house. Fleas and ticks can make both you and your pet miserable. It can make you sick.
Don’t feed raw meat to your pets. And don’t let your cat or dog hunt and eat wild animals. This is how cats get the toxoplasmosis parasite. Keep your pets away from wild animals or stray pets (which may be unvaccinated or sick).
Things to consider
Reptiles (such as lizards, snakes, and turtles) carry bacteria (germs) that can make people sick. If you have a pet reptile, you should wash your hands after handling the pet or anything in its cage. Frequently wash the cage, the area around the cage, and any items used to clean the cage. Children younger than age 5 and people who have weakened immune systems should not handle reptiles or items from the cage.
It’s a good idea to watch toddlers while they play with pets. Small children are more likely to get infections from pets. That’s because children crawl around on the floor with the animals, kiss them, put their fingers in the pets’ mouths, and then put their dirty fingers in their own mouths.
Small children are also more likely to be bitten or scratched by pets. Teach your children how to treat family pets and to avoid strange pets. It may be best to wait until children are past the toddler stage to get a pet.
Children younger than 5 years of age should also avoid with:
- animals at petting zoos and farms
- baby chicks
- baby ducks
- amphibians (such as frogs, toads, and salamanders)
- reptiles (such as turtles, lizards, and snakes)
If you’re planning to get a pet, you might consider adopting an older cat or dog. This way, you can avoid the housebreaking stage and its problems. Older pets that have been well cared for are less likely to spread disease or become ill themselves. Do not take in sick pets or strays. They carry even more risk of making you or your children sick.
