Do Opossums Carry Rabies?
The question of whether opossums can get rabies comes up regularly in public health discussions. While opossums can theoretically contract rabies like most mammals, documented cases in the United States are rare. This is partly attributed to their lower body temperature compared to most mammals, which may make it harder for the rabies virus to survive and replicate effectively.
However, rare does not mean impossible, and exposure decisions should never be made based on assumptions about species. Any bite, scratch, or saliva contact from a wild opossum should be treated as a potential exposure and assessed by a medical professional promptly.
Why Confusion About Opossum Rabies Is Common
Several factors contribute to public confusion about opossum rabies risk:
- Playing possum — opossums sometimes feign death when frightened. This involuntary defensive behavior can be mistaken for neurological symptoms of rabies, causing unnecessary alarm in people who witness it.
- General wildlife caution messaging — public health guidance typically advises caution with all wildlife, which can blur distinctions between higher-risk and lower-prevalence species.
- Regional variation in guidance — some state and local health departments have specific opossum guidance; others treat all wildlife exposures under the same protocol.
What to Do After Opossum Contact
Regardless of the animal involved, the response to a bite or scratch from any wild animal follows the same essential steps:
- Wash the wound immediately — scrub with soap and water for at least 15 minutes. This is one of the most important early actions and should not be skipped under any circumstances.
- Record the details — note the time, exact location, what happened, and the animal's behavior before and during contact.
- Contact your healthcare provider or urgent care — describe the exposure clearly so they can assess whether post-exposure prophylaxis (PEP) is needed.
- Notify local animal control or public health — they may be able to locate and test the animal, which can directly affect your treatment decision.
Can You Wait and Watch for Symptoms?
No. Waiting for rabies symptoms before seeking treatment is not a medically safe strategy. Rabies is almost always fatal once symptoms appear. Post-exposure prophylaxis works only when given before the virus reaches the central nervous system. Do not delay seeking medical advice after a potential exposure while waiting to see how you feel.
How to Reduce Opossum Encounters at Home
Most opossum encounters are avoidable with basic precautions:
- Secure garbage bins with locking lids so food waste does not attract wildlife.
- Do not leave pet food or water outside overnight.
- Seal openings under porches, decks, and sheds that opossums could use as shelter.
- Keep pets vaccinated and supervise them when outdoors, particularly during evening and nighttime hours.
- Do not attempt to handle or relocate opossums yourself — contact local animal control for assistance.
When to Involve Animal Control or Public Health
Contact animal control or your local health department immediately if an opossum has bitten or scratched a person or pet, if the animal is behaving unusually (active during daylight, disoriented, or unresponsive), or if you cannot locate the animal for testing. Do not attempt to capture or contain the animal without professional guidance.
How Opossums Compare to Other US Wildlife
Opossums are biologically unusual — their slightly lower body temperature appears to make them less hospitable to the rabies virus, and CDC surveillance confirms that confirmed opossum rabies cases are uncommon compared to similar-sized mammals. That does not make exposure impossible, just unlikely enough that public health weighs it differently from raccoon or fox exposure.
For context across the high-risk and low-risk wildlife groups, see the full comparison set:
- Raccoons (29% of US wildlife rabies cases)
- Skunks (17%)
- Foxes (8%)
- Coyotes (spillover host)
- Rats and mice (almost never)
- Squirrels (almost never)
- Birds (cannot get rabies — not mammals)
What to Do After Opossum Contact
The risk is low, not zero. If an opossum bit you or your pet, the standard wound-care steps still apply: wash thoroughly with soap and water for 15 minutes, monitor for bacterial infection, and check tetanus status. For an opossum bite that broke skin in a region with active rabies, public health evaluation is reasonable even given the low species-specific risk.

Pets and Opossum Encounters
Pet exposures to opossums happen often — yard fights with cats and small dogs are common. For vaccinated pets, the protocol is much simpler than for unvaccinated ones. See do indoor cats need rabies shots for context on why current pet vaccination dramatically improves outcomes after any wildlife encounter.

Why Opossums Sometimes Look Sick When They Are Not
Opossums frequently 'play dead' (thanatosis) when threatened — a defensive behaviour that can look like collapse or paralysis. They also drool, hiss, and bare teeth as defensive displays. None of these are rabies signs. A normally-behaving opossum that froze or drooled when cornered by your dog has not necessarily been infected. The clinical course of actual opossum rabies, when it does occur, follows the typical wildlife pattern over several days.
