Pet Diseases You Can Catch: What to Know About Zoonotic Risks

We love our pets like family, they bring us joy, comfort, and companionship. But did you know that some illnesses can pass from pets to humans? These are called zoonotic diseases, and while the risk is generally low, being aware of them helps keep both you and your pets safe.

In this article, we’ll explain what zoonotic diseases are, share some of the most common examples, and give you practical tips on how to reduce the risks without losing any of the love.

Zoonotic diseases are infections that can be transferred from animals to humans. They can spread through direct contact with pets, their saliva or waste, or contaminated objects such as food bowls or bedding.

Most healthy people have a low risk of developing serious illness, but extra caution is important for:

• Young children

• Pregnant women

• Older adults

• People with weakened immune systems

1. Ringworm
A fungal infection (not a worm) that causes circular, itchy rashes on human skin. Pets, especially kittens and puppies, can carry ringworm if they have bald patches or scaly skin. Prompt vet care helps stop the spread.

2. Salmonella
Reptiles, amphibians, birds, and some mammals can carry Salmonella bacteria without showing signs. Humans may become sick after handling these pets or contaminated items. Symptoms include diarrhoea, stomach cramps, and fever. Handwashing is your best defence.

3. Toxoplasmosis
Caused by a parasite found in cat faeces. Often mild in healthy people, but dangerous for pregnant women and those with weak immune systems. It’s safest for pregnant women to avoid cleaning litter boxes and always wash hands after handling cats.

4. Cat Scratch Disease (CSD)
Spread by bacteria carried in cats’ claws or mouths. It can cause swollen lymph nodes, fever, and fatigue in humans. Keeping claws trimmed and avoiding rough play lowers the risk.

5. Intestinal Parasites
Roundworms, hookworms, and tapeworms can sometimes spread from pets to people, especially children. Regular worming is an important preventative step.

1. Wash Hands Regularly
After handling pets, cleaning litter boxes, or touching pet food, wash hands thoroughly with soap and water.

2. Routine Vet Check-Ups
Regular vet visits help detect and treat infections early. Your vet can also advise on flea, tick, and worm prevention tailored to your pet’s needs.

3. Food & Hygiene Practices
Wash food and water bowls daily, clean up pet waste promptly, and disinfect enclosures for birds, reptiles, or small mammals.

4. Flea & Tick Protection
Use vet-recommended products year-round. Fleas and ticks can spread diseases that affect both pets and people.

5. Regular Worming
Follow a worming schedule with a product recommended by your vet to protect your pet and reduce human health risks.

The idea of zoonotic diseases can sound worrying, but with proper hygiene, parasite prevention, and routine veterinary care, the risks are very low. Most importantly, you don’t need to distance yourself from your pet, just take sensible precautions.
