Short Answer: Yes — But the Picture Is More Complicated Than Most Wildlife Species
Coyotes can carry rabies, but they are not a primary reservoir species in the US today. Coyotes are spillover hosts — they get infected by other species' rabies variants where those circulate, rather than maintaining a coyote-specific reservoir of their own.
That has not always been the case. Between 1988 and 2008, a canine rabies variant circulated in South Texas coyotes alongside domestic dogs, producing one of the most significant terrestrial rabies outbreaks in modern US history. After a multi-decade oral vaccination program, the canine variant was eliminated from coyote populations and the United States was declared free of canine rabies in September 2008.
Today, the practical answer for anyone bitten by a coyote remains the same: treat it as a exposure requiring prompt professional assessment and seek prompt medical or public-health assessment about whether post-exposure prophylaxis (PEP) is indicated. The detail behind that conclusion is the rest of this article.
The South Texas Canine Variant Story (1988-2008)
A canine rabies strain that had been confined to urban dogs in northern Mexico crossed into South Texas coyotes around 1988 and established itself in the wild canid population.
- 1988-1994: 459 confirmed canine-variant rabies cases in South Texas — 232 in coyotes, 199 in domestic dogs, 28 spillover into other species.
- February 1995: Texas Department of State Health Services launched the Oral Rabies Vaccination Program (ORVP), dropping vaccine-laden baits from aircraft to immunise wild canids.
- September 7, 2008: the CDC declared the United States free of canine rabies — a milestone driven primarily by the success of the South Texas ORVP and parallel programs targeting raccoon and gray fox variants.
This is one of the largest wildlife disease eradication efforts in US history and a reason the practical risk of canine-variant rabies from coyotes is dramatically lower today than in the 1990s.
Where Coyote Rabies Still Occurs
Although coyotes are no longer a self-sustaining reservoir, they continue to be infected with rabies via spillover from other species. Surveillance data shows coyotes infected with:
- Texas gray fox variant — in Arizona and parts of Texas where the gray fox variant is endemic.
- Arizona gray fox variant — particularly in the expanding range that has been monitored since 2022.
- Raccoon variant — in the eastern US enzootic zone (Canada to Florida, east of the Appalachians).
- South central skunk variant — in Texas, Oklahoma, Arkansas, Kansas, and surrounding states.
Bat variants have occasionally been documented in coyotes as well. The bottom line: a coyote encounter in any US region with active terrestrial rabies should be treated as potential exposure. The variant the coyote carries depends on where you are.
How to Tell If a Coyote Might Have Rabies
Healthy coyotes are wary of humans. Urban and suburban coyotes are habituated and increasingly seen in daylight, but they still typically keep their distance. Behaviour that breaks that pattern warrants attention.
Warning Signs
- Approaching humans, pets, or livestock without fear or retreat
- Daytime aggression toward people or other animals
- Staggering, falling, or unable to walk normally
- Apparent paralysis, especially of the hind legs
- Excessive drooling or foaming at the mouth
- Aimless circling or disorientation
- Unusual vocalisations or sounds that seem strangled
- Self-mutilation or biting at the air
What Is Not a Warning Sign by Itself
- A coyote seen in daylight — urban and suburban coyotes are increasingly diurnal as they adapt to human activity.
- A coyote raiding trash, chicken coops, or pet food — opportunistic foraging is normal behaviour.
- Coyotes following hikers or dog walkers at a distance — usually territorial monitoring, not pre-attack behaviour.
- Mange-related fur loss — a parasitic skin condition, not rabies.
Like other wildlife reservoir species, rabies in coyotes can present without obvious neurological signs in the early phase. A normal-looking coyote can still be infectious. This is why any wild coyote bite or skin-breaking scratch warrants prompt professional or public-health assessment regardless of how the animal appeared; a healthcare professional or public-health authority should decide whether PEP is indicated.
What to Do After a Coyote Bite or Scratch
The protocol is the same as for any wildlife exposure requiring prompt professional assessment. Speed matters.
1. Wash and Flush the Wound Thoroughly
Wash and flush with soap and running water for about 15 minutes when possible. Apply povidone-iodine or another antiseptic if available. Wound cleaning alone significantly reduces rabies risk and is the single most important first step.
2. Contact Local Public Health
Call your county or state health department immediately. They will assess exposure, advise whether the coyote can be captured for testing, and direct you to a healthcare facility listing.
3. Begin Post-Exposure Prophylaxis
The standard CDC PEP schedule for an unvaccinated person:
- Day 0: wound washing, human rabies immune globulin (HRIG) infiltrated around the wound, and the first rabies vaccine dose.
- Day 3: second vaccine dose.
- Day 7: third vaccine dose.
- Day 14: fourth vaccine dose.
- Immunocompromised individuals receive a fifth dose on day 28.
If you have completed a full rabies vaccination course previously, only two booster vaccine doses (days 0 and 3) are needed and no HRIG — see PEP for previously vaccinated people.
4. Identify the Coyote If Safely Possible
If the coyote can be safely contained (or has been killed without head damage), animal control can test it for rabies. A healthcare or public-health professional can use a negative test to decide whether PEP should continue. Never try to capture an aggressive coyote yourself — call animal control.

Pet and Livestock Exposure
Coyote-on-pet encounters are increasingly common in suburban areas. Coyotes opportunistically take small dogs, cats, and chickens, and farm dogs in particular are frequent fighters with coyotes.
Dogs and Cats
- Vaccinated pet: most US jurisdictions require an immediate rabies booster within 96 hours and a 45-day home observation period.
- Unvaccinated or overdue pet: outcomes are far stricter — typically a 4-6 month strict quarantine at the owner's cost, or in some states, euthanasia and brain tissue testing.
This is one of the strongest practical arguments for keeping pet rabies vaccinations current — including for indoor cats that may encounter wildlife while in a yard or open garage.
Livestock
Coyote rabies spillover into livestock is uncommon but documented. Rabies vaccines are licensed for several livestock species. In active rabies regions, vaccinating cattle, sheep, and horses can be a cost-effective protection.
How Coyotes Compare to Other US Wildlife Rabies Risks
- Bats: 35% of US wildlife rabies cases. Even no-bite encounters can warrant PEP. See bat exposure guide.
- Raccoons: 29% — higher-concern, eastern US enzootic zone. See do raccoons have rabies.
- Skunks: 17% — higher-concern, three regional variants. See do skunks carry rabies.
- Foxes: 8% — higher-concern by proportion; regional concentration in the Southwest and Alaska. See do foxes carry rabies.
- Coyotes: spillover hosts; canine variant eliminated in 2008. Treat any bite as exposure.
- Opossums: rabies is reported uncommonly — see can opossums get rabies.
- Squirrels, rats, mice: almost never carry rabies — see do rats and mice carry rabies.
Coyotes are unusual in being a wildlife reservoir species that is also a former-reservoir species. The historical canine variant is gone, but the risk from spillover variants remains real in regions where raccoon, fox, or skunk variants circulate.
How to Reduce Coyote Encounters Around Your Property
- Secure trash and compost bins with locking lids.
- Do not leave pet food outside overnight.
- Bring in small pets at dusk and dawn — peak coyote activity.
- Reinforce chicken coops and small-animal enclosures.
- Close off porch, deck, and crawl space access where coyotes might den.
- Vaccinate dogs, cats, and licensed livestock species.
- Teach children to never approach a coyote — even one that looks friendly.
- If a coyote becomes habituated to a neighbourhood, contact local animal control. Habituation is dangerous before it ever becomes about rabies.
