Rabbits are increasingly popular companion animals. Their companionship does not only extend to humans. Dogs and cats which have been well socialized can live very happily with rabbits, although it will depend on the individual animals. While there are a lot of practical and behavioral considerations we need to make when sharing our lives with rabbits, there are often health issues which can be overlooked. Zoonotic diseases, those which can spread from one animal to another, are one of them.
In this AnimalWised article we ask what rabbit diseases are spread to humans? We also find out if rabbits can pass on diseases to other animals in the home. These include viral, bacterial, and fungal infections which can occur when we share close quarters with our rabbits.
Rabbit diseases spread to humans
One of the most common health problems in rabbits is abnormal teeth growth, but this is not something which can be transmitted to humans. Rabbits are more likely to transmit viral, bacterial, fungal, and even parasitic diseases to people, especially if they live in unhygienic conditions. Maintaining proper hygiene and ensuring regular veterinary check-ups can significantly reduce the risk of disease transmission.
This doesn't mean if your rabbit is sick, you will be too. Many bacteria, viruses, fungi, or parasites are species-specific and cannot transfer to humans. Those which can are known as zoonotic diseases or zoonoses. It is crucial to be aware of these diseases to prevent any potential health risks.
Rabbit diseases caused by parasites
Some of the parasitic diseases transmitted by rabbits are:
- Cheyletiellosis: caused by the Cheyletiella parasitivorax mite which affects rabbits. It is highly contagious and capable of infecting people. It produces localized or generalized dermatitis, causing multiple lesions on both the extremities and body. However, since people are not the final host of the mite, these symptoms usually disappear within a maximum of three weeks.
- Giardiasis: Giardia duodenalis is a flagellated protozoan that is transmitted from the feces of infected rabbits. Infected feces is generally pasty and runny. It is especially dangerous in immunosuppressed people or in children, so any change in the appearance of our rabbit's feces should make us suspect this parasite. Regular cleaning of the rabbit's habitat can prevent such infections.
- Leishmaniasis: rabbits have been shown to act as transmitters of Leishmania infantum, but a sandfly mosquito needs to pass between the rabbit and the person for the disease to spread. In people, this disease causes difficulty in breathing and swallowing, ulcers on the skin, mouth and lips, congestion, and nosebleeds. It can also cause visceral leishmaniasis which causes diarrhea, fever, cough, and vomiting in children. Adults may experience symptoms such as fever, fatigue, weakness, loss of appetite, abdominal pain, weight loss, and cold sweats. Protecting your rabbit from mosquito bites is essential.
- Coccidiosis: is a disease caused by protozoa that mainly affects the digestive system and can cause diarrhea (sometimes with blood present), intestinal inflammation, and dehydration. Eimeria is the most important parasite in rabbits and can be transmitted to people mainly via the handling of rabbit feces. Clean and sanitize the living area regularly to mitigate this risk.
- Microsporidiosis: Encephalitozoon cuniculi is a very common parasite in rabbits. If transmitted to humans, it can cause a systemic disease which mainly affects the brain and kidneys. It is crucial to seek veterinary advice if your rabbit shows any signs of illness.
Rabbit diseases caused by fungi
If a rabbit is sick due to a fungal infection, they will have various symptoms. They can transfer diseases to humans, but they won't always display the same symptoms:
- Ringworm: after contact with the skin or hair, we can become infected with the spores of dermatophyte fungi of the Microsporum and Trichophyton genera. The hyphae grow in the outer layer of the epidermis (stratum corneum), lifting the hair cuticle until the hair falls out. Affected rabbits usually have circular alopecic patches, visible red patches on their skin. However, sometimes the animal is an asymptomatic carrier and it is only the caregiver who has the symptoms. When transferred to humans, symptoms include welts and circular areas with reddish edges that itch, mostly located on the neck, chest, and arms. It is advisable to use gloves when handling infected rabbits.
- Sporotrichosis: the fungus Sporothrix schenckii can be transmitted by rabbits and most frequently produce a lymphocutaneous inflammation in humans. There will be the appearance of papules that first turn into pustules, then subcutaneous nodules that slowly expand through the lymphatic system. They can become ulcerated and ooze. Another form is pulmonary (in the lungs). Although this last form is rare, it has a high mortality rate. Early detection and treatment are crucial in managing this disease.
Rabbit diseases caused by bacteria
Among the diseases caused by bacteria that rabbits can transmit to humans are:
- Melioidosis: Burkholderia pseudomallei bacteria cause abscesses in affected organs, such as lungs, spleen, liver, and adjacent nodes. Regular health monitoring of your rabbit can help detect such conditions early.
- Campylobacteriosis: rabbits can transmit Campylobacter jejuni, although the symptoms are not usually serious. Among them are diarrhea, abdominal pain, and fever, but they usually do not last more than a week. It is important to maintain personal hygiene after handling rabbit waste.
- Salmonellosis: rabbits can transmit Salmonella to humans, causing gastroenteric symptoms such as vomiting, diarrhea, abdominal pain, or fever. Ensuring the cleanliness of the rabbit's environment can minimize this risk.
- Pasteurellosis: pasteurellosis in rabbits is a characteristic and very complex disease caused by the bacterium Pasteurella multocida. It is transmitted by bites or scratches from affected rabbits and is characterized by the rapid formation of cellulitis with or without abscesses. Bloody or purulent discharge from the wound is also possible, which can cause septic arthritis in the proximal joint. It can also colonize the human respiratory system, potentially resulting in pneumonia, bronchitis, and lung abscesses. In limited cases, it can affect the abdomen, causing peritonitis. Immediate medical attention is recommended if bitten by an infected rabbit.
- Yersiniosis: another of the diseases that rabbits transmit to people is yersiniosis, caused by the bacteria Yersinia pseudotuberculosis or Yersinia enterocolitica, the latter being the one that generates the most cases in humans and manifests with enterocolitis, diarrhea, fever, and abdominal pain. Systemic infection is associated with liver and splenic abscesses, osteomyelitis, meningitis, and endocarditis. Proper sanitation can help in preventing this bacterial transmission.
- Tetanus: caused by Clostridium tetani, a terrestrial and fecal microbe that rabbits can transmit by biting a person or scratching and they break the skin to create wounds. Vaccination for tetanus is crucial if bitten or scratched.
- Tularemia: also known as Rabbit fever, it is a rare disease caused by the bacterium Francisella tularensis. There are six clinical forms of tularemia, depending on the route of entry: ulceroglandular (the most common, causes skin ulcers), glandular, oculoglandular (affects the eyes), oropharyngeal (affects the digestive system), pneumonic, and septicemic (affects the whole organism). The symptoms infected persons may present include ulcers at the infection site, pain in the eyes, joints, throat, and head, vomiting, diarrhea, fatigue, lymphadenopathy, enlargement of the spleen and liver, coughing, pharyngitis, and skin lesions (erythema). Protecting against direct contact with wild rabbits and using protective gear when handling domestic rabbits can prevent this disease.
- Q fever: Coxiella burnetii is the agent that causes Q fever in rabbits, especially wild rabbits living in mountainous areas. It is transmitted through urine or excrement. In cases that produce symptoms, the wild rabbit can present fever, fatigue, chills, headache, abdominal pain, nausea, vomiting, or diarrhea. Proper protective measures should be taken when handling rabbits from such regions.
Abscesses are particularly dangerous to a rabbit's health since it implies the bacterial infection is acute. Our article on my rabbit has an abscess will tell you more about the causes and treatment of this problem.
Diseases caused by viruses
On the other hand, rabbits can also transmit lymphocytic choriomeningitis. The etiological agent of this disease is an Arenavirus that can be spread to people through the feces of rabbits. It may not cause symptoms. If it does, it may result in fever, encephalitis, or meningitis. If a pregnant woman is infected, it can cause malformations or even fetal death. Fetal mortality is less than 1%. Regular veterinary care and maintaining a clean environment can help prevent viral transmission.
Rabbit diseases spread to cats or dogs
Among the diseases that rabbits can spread to other animals, such as cats or dogs, the following stand out:
Rabbit diseases caused by parasites
Some of the parasitic diseases that rabbits can transmit to our furry ones are:
- Toxoplasmosis: Toxoplasma gondii can be transmitted to our domestic felines by a rabbit. Symptoms depend on the organs affected by the protozoan as they multiply in their cells (stomach, intestine, liver, pancreas, eyes, lymph nodes, skin, muscles, or central nervous system). Regular veterinary check-ups can help in early detection and prevention.
- Cheyletiellosis: Cheyletiella parasotivorax is very common in rabbits and can be transmitted also to our dogs and cats. Symptoms include the presence of flaky skin and itching. Regular grooming and hygiene can help manage and prevent this condition.
- Thelaziosis: Thelazia callipaeda can be transmitted to our dogs and cats via fruit flies. It is a parasite that settles in the conjunctival sac of the eye and causes conjunctivitis, increased serous and tear secretions, as well as itching. Since the host animal tries to scratch the eye, it can cause serious problems. Prompt veterinary treatment is essential to prevent complications.
- Leishmaniasis: rabbits can act as vectors for the Leishmania infantum parasite if they are bitten by a mosquito carrying it. If it then bites a cat or dog, leishmaniasis can be transferred. The lymph nodes become enlarged and various symptoms can stem from the disease. They include increased thirst, increased urination, fever, abnormal nail growth, ulcerations, pustules, lameness, nosebleeds, neurological disorders, and more. Ulcerative and nodular dermatitis on the head or extremities is more common in cats, as well as uveitis and inflammation on the tongue and gums. Protective measures against mosquito bites are crucial.
- Giardiasis: Giardia duodenalis can be transmitted to cats and dogs, producing watery diarrhea which can contain mucus. The prognosis is generally good, but weakened puppies and older or immunocompromised animals are at greater risk. Regular deworming and clean living conditions can prevent such infections.
Rabbit diseases caused by bacteria
As with humans, bacteria can pass from rabbits to other animals. This often occurs due to the animals grooming each other, often being ingested via the mouth. Bacterial infections are one of the most common types of disease in rabbits.
- Campylobacteriosis: rabbits can be a source of Campylobacter jejuni infection in our cats and dogs. However, it produces intestinal inflammation only when they are immunosuppressed or if they have other diseases. Keeping infected animals separated and maintaining hygiene can prevent the spread.
- Yersiniosis: Yersinia pseudotuberculosis can be transmitted to cats, causing a disease characterized by the formation of pus granulomas in a generalized way throughout the body of our feline. It has a poor prognosis. Immediate veterinary intervention is crucial to manage the condition.
- Tularemia: as with humans, Francisella tularensis can be transmitted from an infected rabbit to cats and dogs. It can cause ulcers on the tongue and palate, as well as anorexia, dehydration, muscle pain, organ enlargement, and fever. It is more common in cats than dogs. Protective measures and regular health check-ups can aid in prevention.
Rabbit diseases caused by fungi
As for the diseases caused by fungi that rabbits can transmit to other animals, the following stand out:
- Sporotrichosis: in dogs, Sporothrix schenckii is involved in the formation of nodules throughout the body, although mainly on the abdomen and head. They are also sometimes formed in the liver, lungs, and bones instead of the skin. In cats, sporotrichosis varies from an asymptomatic infection to a fatal systemic disease. The nodules usually appear on the extremities, base of the tail, or the head, which can spread as the cat grooms themselves. Nodules can become ulcerated and reach internal organs, causing weight loss, anorexia, fever, depression, and dyspnea (shortness of breath). Early detection and antifungal treatment can improve outcomes.
- Dermatophytosis or ringworm: rabbits can be a source of Trichophyton mentagrophytes and Microsporum canis infections. These are characterized by the formation of various dermatological lesions, particularly when patches of hair fall out from the animal's coat. Generalized forms cause generalized alopecia, but other skin damage is likely. Maintaining a clean environment and avoiding contact with infected animals can help in preventing the transmission.
How can I prevent my rabbit from spreading disease?
If we keep a rabbit, we want them to be healthy and not worry about diseases transferring as we handle them. While some of the above problems cannot be directly avoided, there are things we can do to best prevent disease. They include:
- Vaccination and deworming schedule: keep vaccines and deworming for rabbits up to date. This is crucial in preventing both common and serious infections.
- Monitor feces: observe for changes in feces to find out if they may be sick. Avoid contact with dogs, cats, and children if so since, as we have seen, many of the diseases mentioned are transmitted in this way. Regular cleaning of the rabbit's living space can prevent the spread of infections.
- Veterinary checkups: take the rabbit to a vet specializing in exotic pets if they ever seem depressed, have alterations in behavior or have clinical signs of disease. Prompt diagnosis and treatment will improve the prognosis. Regular health check-ups can catch potential issues early.
- Reduce stress: although rabbits can only pass on physiological diseases to humans, they are more likely to be unwell if they are stressed. Look out for signs of stress in rabbits and do what you can to eliminate stressors from their environment. Providing a calm and stable environment is key.
- Monitor their skin: monitoring the rabbit's skin frequently to look for lesions compatible with parasites, as well as trying to prevent mosquitoes from biting him, is important to control the good health of our pet. Early detection can prevent further complications.
- Personal hygiene: it is important to wash our hands after being in contact with the rabbit's feces or urine. If you have dogs or cats that may have contact with wild rabbits or their entrails, it is especially important to keep them under control. Good hygiene practices are essential in preventing disease transmission.
