Worms in pets are a common concern for many pet owners. The thought of catching worms from our beloved cats or dogs can be unsettling. So, Can Humans Get Worms From Cats Or Dogs? The short answer is yes, certain types of worms can be transmitted from pets to humans. However, it’s not as simple as just petting your furry friend. Understanding how these transmissions happen and what you can do to prevent them is key to keeping both you and your pet healthy.
Understanding Zoonotic Worms: What Are They?
Zoonotic diseases are illnesses that can be passed between animals and humans, and some types of parasitic worms fall into this category. These worms are not just limited to dogs; cats can also be carriers. It is important to note that not all worms found in pets are transmissible to humans, and even when they are, the risk can be greatly reduced through simple preventative measures. The most common types of worms that can be passed from pets to humans include roundworms, hookworms, and, less frequently, tapeworms. While less common, heartworms, a dangerous parasite in dogs and cats, are not transmissible to humans.
How Can Humans Get Worms from Pets?
Transmission of worms from pets to humans generally occurs through the ingestion of worm eggs or larvae found in the environment. Unlike [ear mites in dogs can humans get it], you won’t directly catch worms simply from petting an infected animal. Here are some common scenarios where transmission can occur:
- Accidental ingestion: This is the most common route. Children, especially, might accidentally ingest contaminated soil or sand while playing outside. If your pet has worms and defecates in the yard, the eggs or larvae can contaminate the soil. This can also occur if you do not wash your hands after cleaning up after your pet.
- Contact with infected feces: Coming into contact with pet feces that contain worm eggs or larvae, then touching your mouth or food, can lead to infection.
- Skin penetration: Hookworm larvae can penetrate the skin, particularly through bare feet. This is usually a risk when walking on contaminated soil or sand.
Dr. Emily Carter, a veterinary parasitologist, says, “The risk of humans catching worms from pets is real, but with proper hygiene practices, it can be minimized. Regular deworming of your pets is also an important step in preventing transmission.”
Types of Worms Transmissible to Humans
Let’s delve deeper into the specific types of worms that pose a risk to humans:
Roundworms
Roundworms are quite common in dogs and cats. The eggs are passed through the feces and can contaminate the environment. Humans can accidentally ingest these eggs, leading to larval migration in the body. The larvae may not fully develop into adult worms in humans, but can migrate to various organs causing visceral larva migrans or ocular larva migrans if it migrates to the eye.
- Symptoms in Humans:
- Fever
- Fatigue
- Abdominal pain
- Coughing
- Eye problems (in cases of ocular larva migrans)
Hookworms
Hookworms are also common in pets and are known for their ability to penetrate the skin. In humans, hookworms often cause a skin condition called cutaneous larva migrans, where the larvae tunnel through the skin causing itchy, red tracks.
- Symptoms in Humans:
- Itchy, red, and raised tracks on the skin
- Localized swelling
- Discomfort in the affected area
Tapeworms
Transmission of tapeworms from pets to humans is less common and usually involves accidental ingestion of fleas that are infected with tapeworm larvae. In pets, tapeworms live in the small intestine, but human infection is less frequent and usually milder.
- Symptoms in Humans:
- Abdominal pain
- Nausea
- Weakness
- Rarely, weight loss
It’s important to emphasize that these worms do not typically complete their life cycle in humans in the same way that they do in dogs or cats. That’s why the symptoms and impacts can be different. Regular parasite prevention in dogs is essential for protecting them, but it is beneficial for the entire family’s health as well.

How to Prevent Worm Transmission from Pets to Humans
Preventing worm transmission requires a multi-pronged approach, involving good hygiene practices, regular veterinary care for your pet, and responsible pet ownership.
-
Practice Good Hygiene:
- Wash your hands thoroughly with soap and water after handling your pet, cleaning up pet waste, and before eating.
- Teach children to do the same.
- Avoid touching your face, especially your mouth, after handling pets or being outdoors where pets might have been.
- Use gloves when cleaning litter boxes or picking up pet feces.
-
Regular Deworming for Pets:
- Work with your veterinarian to develop a regular deworming schedule for your pet. This is crucial to prevent and control worm infestations. Many effective medications are available, and your vet can recommend the best option based on your pet’s needs.
- Administer prescribed deworming medication at the recommended intervals to ensure that any worms are effectively eliminated.
-
Control Fleas:
- Fleas can carry tapeworms, so preventing flea infestations helps to reduce this risk. Use a [good over the counter flea treatment for dogs] or a flea preventative prescribed by your veterinarian.
- Regularly check your pet for fleas, especially during warmer months.
-
Proper Waste Disposal:
- Always dispose of pet feces properly, either in sealed bags or by flushing it down the toilet (if your plumbing system can handle it).
- Do not leave pet waste in the yard, and clean it up promptly.
- Clean litter boxes frequently, and use a scooper and gloves to minimize contact with the waste.
-
Supervise Children:
- Supervise young children carefully when they play outdoors, especially in areas where pets have access.
- Encourage them not to put their hands in their mouths or play with soil.
- Teach children about the importance of washing their hands after playing outside.
-
Keep Your Yard Clean:
- Regularly clean up and maintain your yard to remove pet waste and reduce the chance of contamination.
- Avoid using sandboxes if your pet can access them because they can be difficult to keep clean from feces.
-
Routine Veterinary Care:
- Regular veterinary check-ups will ensure that your pet is healthy and free from worms, thus reducing the risk of transmitting them to you or other family members.
- Follow your veterinarian’s recommendations for testing and treatment.
- Discuss any concerns you have about worm prevention and transmission with your veterinarian.
Dr. Ben Williams, a family practice physician specializing in zoonotic diseases, notes, “Education is a crucial tool in preventing the spread of zoonotic worms. Simple steps like handwashing and deworming pets can dramatically reduce the risk to humans.” Remember, prevention is key to a healthy home for both you and your pets.
Addressing Common Misconceptions
There are some common misconceptions about worms in pets that need to be addressed:
- Misconception 1: If my pet doesn’t go outside, they can’t get worms. Indoor pets can still get worms. Some worms are transmitted by fleas, which can be carried inside. Additionally, the eggs can be tracked inside on shoes.
- Misconception 2: If I don’t see worms in my pet’s stool, they don’t have worms. Many types of worms do not show up in the stool, and their presence might be indicated by more subtle signs, or only in a vet check.
- Misconception 3: Only puppies and kittens get worms. Adult dogs and cats can also get worms. Regular deworming is important at all ages.
- Misconception 4: It is okay to leave pet feces on the ground in my backyard because nature will take care of it. Leaving feces on the ground contaminates the soil, thereby increasing the chance of infection in people.
- Misconception 5: If humans get worms they will always experience obvious symptoms. The symptoms can be mild or absent, but infection can still occur and cause health complications later if it is left untreated.

When to Seek Medical Advice
If you suspect you have a worm infection from your pet, it’s essential to see a doctor. Do not attempt to self-diagnose or treat the problem, as medications that work for pets will not work for humans.
- Symptoms to Watch For:
- Persistent abdominal pain or discomfort
- Itchy skin with red tracks
- Unexplained fatigue, fever, or cough
- Eye issues, such as redness, pain, or decreased vision
- Sudden weight loss or increased appetite with weight loss.
Your doctor can perform the necessary tests and prescribe the appropriate treatment to clear the infection and prevent complications.
Conclusion
Can humans get worms from cats or dogs? The answer, as we’ve seen, is yes, but the risk can be greatly minimized with responsible pet ownership and good hygiene practices. Regularly deworming your pet, practicing thorough handwashing, properly disposing of pet waste, and seeking veterinary care when needed are all essential steps. By staying proactive and informed, you can enjoy the companionship of your furry friends while keeping your family safe and healthy.
