Should You Worry When Your Cat Sneezes on You?


Cats make wonderful pets for many people. In the United States alone, over 42 million households have at least one cat. With so many furry feline friends living amongst us, it’s understandable that cat owners may worry about catching an illness from their pet.

While it’s relatively rare, some diseases can be transmitted from cats to humans. According to the Centers for Disease Control and Prevention (CDC), more than 200 human diseases are spread through animals.

So how likely is it that you’ll get sick if your cat sneezes on you? Let’s take a closer look at the risks and how to stay healthy around our beloved kitties.

Transmission of Illnesses from Cats to Humans

Cats can transmit a variety of illnesses and diseases to humans through various forms of contact. Some of the main ways cats spread diseases include:

  • Cat saliva – Cats spread illnesses like cat scratch disease and rabies through bites and saliva. A cat sneezing directly on your face could potentially transmit disease through saliva droplets.
  • Cat scratches – Cats have bacteria under their claws that can cause infection when they scratch a person, even if it seems minor. Cat scratch disease is a common illness spread this way.
  • Fecal contamination – Cat feces can contain parasites like toxoplasmosis and roundworms. These can be transmitted by ingesting contaminated water/food or through improper hygiene.
  • Flea/tick bites – Cats can harbor fleas and ticks carrying illnesses like Bartonella, the bacteria that causes cat scratch fever.
  • Airborne transmission – Some respiratory viruses like bordetella bronchiseptica can spread through the air when an infected cat sneezes or coughs near you.
  • Contact with fur – Ringworm, a fungal skin infection, can be spread by touching an infected cat’s fur and then touching your own skin.

In summary, cat saliva, scratches, fleas, contaminated feces, and respiratory droplets can all potentially transmit illnesses to humans. Proper hygiene like handwashing is important to reduce risk.

Common Cat Illnesses that can Infect Humans

There are several illnesses that cats can transmit to humans. Some of the most common include:

Toxoplasmosis: This parasitic disease is caused by Toxoplasma gondii. Cats contract it by eating infected rodents, birds or other small animals. The parasite is then shed in the cat’s feces for up to 3 weeks. Humans can contract toxoplasmosis by accidentally ingesting infected cat feces, either through poor hygiene or environmental contamination. Pregnant women are at highest risk because the parasite can cross the placenta and cause birth defects. Most infected people show no symptoms, but toxoplasmosis can cause flu-like illness, swollen lymph nodes and, rarely, more serious issues like encephalitis or organ damage in those with weakened immune systems [1].

Ringworm: Despite its name, this fungal skin infection has nothing to do with worms. About 10% of cats carry ringworm, which spreads through direct contact with an infected cat’s skin or fur. In humans, ringworm causes a reddish, circular rash with clearing in the center. Though not serious, ringworm can be persistent and contagious [2].

Cat Scratch Disease: A bacterial infection caused by Bartonella henselae, cat scratch disease is transmitted through bites and scratches, usually from kittens. Symptoms appear 3-14 days after exposure, including swollen lymph nodes, fever, headaches, and fatigue. Cat scratch disease usually resolves on its own but may require antibiotics in severe cases [3].

Symptoms and Effects of Cat-Transmitted Illnesses

Some of the most common illnesses that can be transmitted from cats to humans include toxoplasmosis, cat scratch disease, ringworm, and internal parasites like hookworms or roundworms. The symptoms and severity can vary depending on the specific illness.

Toxoplasmosis is one of the most well-known cat-transmitted diseases. According to the CDC, most healthy people infected with toxoplasmosis may not have any symptoms at all. However, some symptoms can include muscle aches, fever, swollen lymph nodes, and fatigue. For those with weakened immune systems, toxoplasmosis can cause more severe symptoms and even damage to the brain, eyes, or other organs. Toxoplasmosis is usually treated with antibiotics [1].

Cat scratch disease results from a bacterial infection transmitted through a cat scratch or bite. Symptoms generally appear 3-14 days after exposure and can include fever, fatigue, loss of appetite, and swollen lymph nodes near the scratch/bite. The infection usually resolves on its own, but antibiotics may be used for severe cases. Long-term complications are rare [2].

Ringworm is a fungal skin infection that causes a ring-shaped rash on the skin. Other symptoms can include itching, redness, scaling, and hair loss. Oral anti-fungal medications are commonly used to treat ringworm infections. The rash usually clears up within 4 weeks with treatment [3].

Intestinal parasites like hookworms or roundworms may not cause any symptoms, or could result in gastrointestinal issues like diarrhea, nausea, or abdominal pain. Antiparasitic drugs are used to kill the worms. Hookworms can also enter through the skin, causing cutaneous larva migrans – a winding rash on the skin [4], [5].

While most cat-associated illnesses do not cause serious or long-term problems in healthy adults, some can be more dangerous for pregnant women, infants, young children, the elderly, or immunocompromised individuals. Consult a doctor if any concerning symptoms develop after exposure to a cat.

Likelihood and Risk Factors

The likelihood of becoming ill from a cat sneezing directly on you is actually quite low. According to experts, cat sneezes do not contain enough force to effectively spread germs or bacteria to humans ( Cats can occasionally carry organisms like chlamydia that cause sneezing, but transmission to humans is rare ( Brief exposure to a sneezing cat is generally not enough for disease transmission.

That being said, certain risk factors can increase the chances of becoming sick from a sneezing cat:

  • Having a weakened immune system or chronic health condition
  • Being in close proximity to a cat as it sneezes directly on your face
  • Exposure to a cat with a known upper respiratory infection
  • Letting a sneezing cat lick your face or hands
  • Not washing your hands after exposure to sneezing cat

For most healthy adults, the risk is very minimal. But those with compromised immune systems should take precautions around cats with respiratory infections.

Preventing Illness Transmission from Cats

There are several effective ways to help prevent catching an illness from your cat:

Practice good hygiene – Always wash your hands with soap and water after touching cats, cleaning their litter boxes, or handling their food. Avoid touching your face until after handwashing. Consider wearing gloves when cleaning litter boxes.

See your vet regularly – Keep your cat’s vaccinations and preventive care up to date to reduce the risk of disease. Kittens should be vaccinated on a schedule starting at 6-8 weeks old. Annual exams allow screening for parasites and illnesses.

Control fleas and ticks – Talk to your vet about safe and effective flea and tick control products. Eliminating these parasites reduces the risk of diseases like bartonellosis (“cat scratch fever”).

Clean the litter box daily – Scoop waste out of litter boxes daily, and clean them thoroughly each week with soap and hot water to destroy germs. Consider using a clumping litter that locks in waste.

Avoid bites and scratches – Play gently with cats and avoid rough play that could lead to injuries. Seek prompt medical care for any bites or scratches that break the skin.

Limit access to young children or immunocompromised people if your cat is ill – Just like with human illnesses, keeping vulnerable people away from a sick cat can help prevent disease spread.

Seek prompt veterinary care for any ill cats – Cats that seem unwell should be seen by a vet, both for the cat’s sake and to reduce any potential human health risks.

With some simple precautions, cat owners can continue enjoying the many benefits of feline companionship while minimizing the risk of zoonotic disease transmission.

When to See a Doctor

In most cases, coming into contact with a sneezing cat is harmless. However, there are some circumstances when you should see a doctor after exposure to a cat:

If you develop concerning symptoms like fever, respiratory distress, skin rashes, or swelling, seek medical attention promptly. According to the CDC, symptoms of serious illnesses like rabies can take days to months to appear after exposure to a rabid animal [1]. Immediate treatment is vital.

See a doctor if you were bitten or scratched and the wound appears infected. Cat bites and scratches can introduce bacteria deep into the skin and cause infections. Signs of infection include redness, swelling, pain, pus, and fever.

People with weakened immune systems, pregnant women, infants, and the elderly should consult a doctor after contact with a sneezing cat, even without symptoms. Their vulnerable health may put them at higher risk of illness.

If you suddenly develop wheezing, shortness of breath, watery eyes, or other allergy symptoms around cats, see an allergist. You may have developed new cat allergies and need treatment and avoidance recommendations [2].

In general, contact your doctor any time you have concerns about possible illness transmission from a cat. They can assess your symptoms, risk factors, and recommend appropriate diagnostic tests and treatment.

Caring for an Ill Cat

If your cat has contracted an illness that is transmissible to humans, it is important to take proper precautions while caring for them. This will help prevent the spread of disease. Here are some tips:

  • Wear disposable gloves when handling litter boxes, feeding dishes, or cleaning up any vomit or diarrhea. Wash hands thoroughly afterwards.
  • Disinfect any surfaces the cat has contact with using a cleaner safe for pets (
  • Wash bedding, fabric toys, pet carriers, and other washable items regularly.
  • Have the ill cat use a separate litter box from other pets.
  • Keep the cat isolated from other pets to prevent disease spread.
  • Monitor the cat for worsening symptoms and contact your vet if needed.
  • Follow any additional precautions recommended by your veterinarian.

With proper care and hygiene, you can safely care for an ill cat while protecting your own health. But if symptoms worsen or you have concerns, don’t hesitate to call your vet.

Key Takeaways

The chances of catching an illness directly from a cat’s sneeze are low for most people. However, some key points to remember are:

  • Certain groups like pregnant women, infants, young children, elderly, and immunocompromised individuals are at higher risk.
  • Diseases cats can transmit include toxooplasmosis, campylobacteriosis, cat scratch disease, ringworm, and more.
  • Prevent illness by washing hands after contact, avoiding scratches/bites, proper litter box hygiene, keeping cats indoors, and routine vet visits.
