Not sure whether a bite or scratch is dangerous? This free rabies risk calculator is a 60-second risk assessment tool that walks you through the same factors a clinician weighs after an animal exposure. To know if you are at risk for rabies after a bite or scratch, it checks whether the skin was broken, whether saliva reached a wound or your eyes, nose, or mouth, whether a bat was in a sleeping area, and whether the animal was wild, stray, unknown, unvaccinated, or unavailable for observation.
One of the most common questions is “can a scratch without blood cause rabies?” A scratch that does not break the skin and has no animal saliva on it carries very low risk — but scratches often create tiny breaks you cannot see, and if a rabid animal's saliva touched the area, transmission is possible. When the animal was wild, stray, or unknown, treat any skin-breaking scratch as a possible exposure rather than relying on the absence of blood. Rabies is almost always fatal once symptoms begin, yet nearly 100% preventable when post-exposure care starts early, so it is always safer to check.
Answer the questions below to get a personalized High, Possible, or Lower concern result with clear next steps.

Answer the questions below
Select Yes or No for each question
Did a bite break the skin?
Any puncture, tear, or abrasion caused by an animal's teeth
Did a scratch break the skin?
Claw or nail scratch deep enough to draw blood or open the skin
Did animal saliva touch your eyes, mouth, nose, or an open wound?
Lick on a cut, mucous membrane contact, or splash into the eye
Was a bat found in a room where someone was sleeping?
Bat bites can be painless and unnoticed — this is treated as a possible exposure
Was the animal wild, stray, unknown, or acting strangely?
Raccoons, foxes, skunks, bats, stray dogs or cats, or any animal behaving abnormally
Is the animal unavailable for observation or testing?
Ran away, could not be captured, or was not brought to a vet
Was it a vaccinated dog, cat, or ferret whose owner can confirm vaccination?
Vaccination records available and animal is currently under observation
Did the exposure happen outside the United States?
Rabies risk varies significantly by country — higher risk in parts of Asia, Africa, and Latin America
What to do after a possible rabies exposure
Wash the wound immediately
Soap and running water for at least 15 minutes. This is the single most effective first aid step.
Do not wait for symptoms
Rabies symptoms appear only after the virus reaches the brain — by then it is too late to prevent. Act now.
Seek medical evaluation
A doctor or public health authority decides whether PEP (post-exposure prophylaxis) is needed for your situation.
Complete the full course of PEP if recommended
PEP is a series of shots over 14 days. Stopping early reduces its effectiveness.
This tool does not replace medical advice
The risk level shown is based on general guidance from the CDC and WHO. Only a licensed healthcare professional or public health authority can confirm whether you need PEP. When in doubt, seek care — it is always better to ask than to wait.
