When I was growing up, the family dog wasn’t allowed in the house, and the cats wandered in and out at will. Now, our cats are strictly indoors, the dog sleeps on her bed at the foot of mine, and my son keeps a snake in his room.

Over the past several decades, society’s attitudes have changed on the roles of pets in our lives, and we keep them in close proximity as part of the family. In fact, , which also brings us in closer contact with zoonotic diseases. No, those aren’t diseases you catch at a zoo. Well, you could at a petting zoo, but the term “zoonotic” simply means that a particular illness can be shared between humans and animals.

“While pets can make us sick, they offer their human companions more benefits than risk,” says . “Studies have shown they provide good health, emotionally and physically.”

That said, it’s still wise to be aware of the most common infectious diseases you can catch from your pet. Dr. Sykes provides a short list and tips on how to protect the health of your pets and family.

These are intestinal parasites often found in puppies and kittens. The eggs or larvae are passed through the animal’s feces. Hookworm can cause painful, itchy skin infections in humans. Roundworms may cause no symptoms in some people, but cause eye damage in others, especially young children that come into contact with pet feces.

How to reduce your risk:

• Have your kittens and puppies dewormed by the vet as soon as you bring one home.
• While gardening, don’t walk barefoot and do use gloves.
• Always wash hands after petting a dog or cat, especially young animals.

Not actually a worm, this disease is caused by a fungal infection within the top layer of the skin. It’s highly contagious and can be passed among dogs, cats, horses, other animals and humans. You can also contract it from surfaces that an infected pet or person has touched, especially if you’ve been sweating a lot or have a minor skin abrasion. It causes a ring-shaped, itchy red that may be dry and scaly, or wet and crusty. Sykes says ringworm can be difficult to prevent but responds well to treatment.

How to reduce your risk:

• Avoid direct contact with infected animal or person until the ringworm is gone.
• until it is clear what is causing the skin problem.
• Wash sheets and pajamas of an infected family member daily. Seek immediate medical treatment from a veterinarian if your pet has skin lesions or consult a doctor for humans showing signs of infection.

Reptiles such as lizards, snakes and turtles are likely sources of this infection, as well as chicks and ducklings. Dogs, cats, birds and horses may also carry it. Signs and symptoms may include , and fever.

How to reduce your risk:

Symptoms can include: bull’s-eye rash at the site of tick attachment, fever, headache, muscle or . While Lyme does not manifest symptoms in all of those infected, without prompt treatment, it can become a chronic condition over time, causing nerve and , mental changes and pain.
