The threat of rabies often evokes images of stray dogs and wild carnivores, but questions sometimes surface about its presence and risks in lagomorphs—a taxonomic order that includes rabbits, hares, and pikas. Concerns surrounding these commonly encountered mammals, both as pets and in the wild, highlight the need for a nuanced exploration of rabies transmission dynamics, clinical presentation, and risk management for humans and animals alike.
Rabies is a viral zoonosis caused by lyssaviruses, most commonly Rabies virus (RABV), known for its devastating impact on the central nervous system of mammals. Transmission typically occurs through the bite of an infected animal, as saliva delivers the virus directly into tissues. The disease is nearly always fatal once clinical signs appear.
While more than 99% of human cases stem from dog bites globally, the virus circulates among diverse wildlife reservoirs, particularly carnivores and bats. In North America and much of Europe, skunks, raccoons, foxes, and various bat species serve as primary reservoirs.
Lagomorphs—including domestic and wild rabbits—are not natural reservoirs for rabies. Documented infections are rare, and the vast majority of exposures leading to disease in humans or other animals do not trace back to these species. In field studies, only isolated incidents of rabies in lagomorph populations have ever been reported.
“Rabbits, both domestic and wild, are considered highly susceptible to rabies if exposed, but their role as a natural source of infection is minimal,” notes Dr. Erin Shealy, a veterinary epidemiologist.
The primary risk for lagomorphs arises from predatory attacks. Wild rabbits or hares may be bitten by rabid carnivores, such as foxes or raccoons. Domestic rabbits are vulnerable if left outdoors or in poorly secured enclosures. Despite this, actual transmission events are exceedingly rare due to several factors:
Cases of rabid rabbits have surfaced sporadically in the medical literature. Notably, an outbreak in the United States in the late 1990s involved a domestic rabbit bitten by a rabid raccoon, with subsequent monitoring of human and animal contacts. No secondary cases were identified. Such scenarios, while striking, underscore the exceptional nature of confirmed rabies in lagomorphs.
Infected lagomorphs often display neurological symptoms similar to those seen in carnivores, including:
Because these signs overlap with several other diseases (e.g., encephalitozoonosis, heatstroke, trauma), diagnosis often demands laboratory confirmation through direct fluorescent antibody testing after death.
Instances of humans contracting rabies from lagomorphs are nearly unheard of. The Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) both classify rabbits and other lagomorphs as low-risk species. However, caution is warranted in any case of abnormal behavior or unexplained neurological illness in a rabbit with potential exposure history.
In the rare event of a suspected rabid lagomorph bite, the following steps are advised:
Significantly, most guidelines do not recommend blanket PEP for rabbit bites unless the animal demonstrated clear neurological dysfunction and a plausible exposure route to a rabies reservoir.
“The risk of rabies transmission from lagomorphs to humans is so low that routine rabies vaccination is unnecessary; instead, emphasis should be placed on educating owners about wildlife exposure risks,” says Dr. Juan Martinez, infectious disease specialist.
Owing to their generally indoor lifestyle and the absence of a rabies vaccine specifically approved for rabbits, preventive efforts center on environmental management:
Wild lagomorphs serve as sentinels rather than reservoirs. Their deaths following predator attacks can indicate the presence of rabies in local mesocarnivore populations. Nonetheless, systematic testing of wild rabbits for rabies is not routine except in unusual cluster events or epidemiological investigations.
When compared with notable carriers such as raccoons, bats, or skunks, lagomorphs pose a vanishingly small rabies risk. For context:
It is not uncommon for public anxiety to arise following rabbit bites, but well-documented case reviews consistently demonstrate minimal transmission danger.
The 2017 Texas surveillance report identified no rabies-positive lagomorphs among thousands of animals tested—a pattern mirrored in other states and countries with robust rabies control programs. Even in regions facing wildlife rabies outbreaks, lagomorph involvement is typically negligible.
However, vigilance remains essential in border regions or during rabies epizootics. For example, during a raccoon rabies spike in the northeastern United States, veterinarians and wildlife officials temporarily heightened oversight regarding any unexplained lagomorph morbidity.
Lagomorphs hold little direct significance in rabies epidemiology, either as sources for human infection or as transmitter hosts in the wildlife cycle. Nonetheless, prudent observation and rapid reporting of unusual events allow health professionals to maintain perspective—and public confidence.
Effective rabies prevention focuses on high-risk animals, prompt wound care, sensible animal husbandry, and public awareness. For owners of rabbits and wildlife professionals, the key principle is proportional caution without disproportionate alarm.
Transmission of rabies from rabbits to humans is extremely rare. Most health agencies do not consider lagomorphs significant sources of rabies risk.
A rabies shot is usually unnecessary after a rabbit bite unless the animal was behaving abnormally and may have been exposed to a rabid predator. Consult a healthcare professional for personalized risk assessment.
Currently, there is no widely approved rabies vaccine for rabbits, and routine vaccination is not required or recommended. Emphasis should be placed on preventing exposure to wildlife.
Immediately isolate the rabbit and contact a veterinarian for guidance. The rabbit should be monitored for signs of illness, and local authorities may recommend quarantine or testing depending on the scenario.
Keep pet rabbits indoors or in secure outdoor enclosures, supervise any outdoor activity, and prevent contact with wild mammals known to transmit rabies.
