After a possible exposure: Seek prompt professional assessment; do not wait for observation to finish. Public-health authorities can arrange a full 10-day observation for an eligible dog, cat, or ferret and use the result to guide PEP. Do not start, delay, or stop PEP on your own. A clinician or public-health professional should assess the animal, type of contact, wound depth and site, where the encounter happened and local rabies activity, and options for observation or testing.
How Professionals Assess Possible Rabies Exposure
You should promptly contact a clinician or public-health authority if you were bitten, scratched, or licked on broken skin by a mammal that could carry rabies, even if it is available for observation or testing — especially a bat, raccoon, skunk, fox, or an unknown stray. Some situations are generally lower concern, including contact with a healthy, vaccinated pet available for observation and typical contact with small rodents or rabbits in the United States. A professional should still assess unusual or uncertain details. When in doubt, wash the wound and call a health professional — the decision depends on the animal, the type of contact, and whether the animal is available.
This page is a general guide. For a personalized read on your specific situation, use our rabies exposure checklist, which walks you through the same factors below.
Three Questions Professionals Assess
Rabies risk comes down to three things (CDC):
- What animal was it? Higher-concern species (bats and wild carnivores) versus low- or species in which rabies is reported uncommonly (rodents, rabbits).
- What kind of contact? A true exposure is a bite, a scratch that breaks skin, or saliva contacting a wound or mucous membrane. Petting an animal or contact with its blood, urine, or feces is not a rabies exposure.
- Can the animal be observed or tested? A healthy dog, cat, or ferret can be watched for 10 days; if it stays well, public-health guidance generally considers that it was not infectious at the time of contact. A wild or unavailable animal cannot be cleared, which raises the risk.
By Animal Type
Bats — treat seriously
Bats are the leading cause of human rabies deaths in the US. Bites can be tiny and painless. If you wake to a bat in the room, find a bat near a child or someone who was asleep or unable to report a bite, prompt professional or public-health assessment is important, and the testing result can inform whether PEP is indicated. See what to do if a bat gets into your home.
Raccoons, skunks, foxes, coyotes — prompt professional assessment after exposure
These wild carnivores are the main rabies reservoirs in the US. A bite or skin-breaking scratch warrants prompt professional or public-health assessment because observation may not be possible and testing requires the animal.
Dogs, cats, and ferrets — often observable
For an eligible dog, cat, or ferret, authorities may arrange supervised 10-day observation. Seek prompt assessment first; a healthy appearance at the time of contact cannot rule out infectiousness. If the animal is healthy at 10 days, public-health guidance generally considers that it was not infectious at the time of contact. If the animal cannot be found or observed, seek prompt professional or public-health assessment. See dog bite rabies PEP assessment factors
Rodents and rabbits — almost never
Small rodents (mice, rats, squirrels, chipmunks, hamsters, gerbils, guinea pigs) and rabbits/hares are almost never found to be rabid and have not been known to cause human rabies in the US. These bites are generally lower concern for rabies in US surveillance, but a clinician or public-health authority should assess unusual circumstances and decide whether PEP is indicated.
Livestock and other mammals
Horses, cattle, and other mammals can rarely get rabies. These are judged case by case with your health department based on local rabies activity.
By Type of Contact
- Bite that breaks skin: seek professional or public-health assessment for rabies PEP.
- Scratch that breaks skin, if contaminated with saliva: can be an exposure; assess.
- Saliva on broken skin, eyes, nose, or mouth: counts as an exposure.
- Touching or being near the animal, or contact with blood/urine/feces: not a rabies exposure.
Quick Reference: Details to Discuss
Use this as a starting point, not a substitute for professional advice:
- Situations needing prompt professional assessment: bat contact (including a bat in the room while sleeping); bites or skin-breaking scratches from raccoons, skunks, foxes, coyotes, or bobcats; any bite from a stray or wild animal that can't be observed or tested.
- Seek prompt assessment; professionals may arrange observation: bites or scratches from an owned dog, cat, or ferret that appears healthy and can be watched 10 days.
- Situations usually assessed as lower likelihood: bites from mice, rats, squirrels, chipmunks, hamsters, gerbils, guinea pigs, rabbits, or hares; petting an animal; contact with blood, urine, or feces.
Special Situations That Change the Answer
Someone who was asleep, very young, or can't report a bite
Bat bites can be too small to feel or see. If a bat is found in a room with a sleeping person, an unattended child, or someone who can't reliably say whether they were bitten, health authorities assess whether PEP is indicated, and a test result may inform that decision. This is the scenario behind most US human rabies cases.
People with weakened immune systems
Under US guidance, people with immune disorders need a fifth PEP vaccine dose on day 28 and antibody testing after the course, with clinician and public-health follow-up. Mention any condition or medication that affects your immune system when you're evaluated.
Travel and dog bites abroad
In many countries, dog rabies is common and animals can't be reliably observed. A dog bite while traveling in a rabies-endemic region is generally treated as a real exposure — seek care locally and don't wait to get home.
Contacts Generally Not Classified as Rabies Exposures
It helps to rule things out. These are not generally considered rabies exposures:
- Petting or handling an animal, even a rabid one, with intact skin
- Contact with an animal's blood, urine, feces, or skunk spray
- Contact confined to intact skin, with no saliva contact with eyes, nose, or mouth
- Touching a dead animal with gloves and intact skin (still wash and be cautious)
If the described exposure routes do not appear to apply, the situation may be lower concern, but a healthcare professional or public-health authority should assess uncertain details and decide whether PEP is indicated.
When Details Are Uncertain: Seek Professional Guidance
- Wash and flush the wound with soap and running water for about 15 minutes when possible. This alone dramatically reduces risk.
- Note the animal: species, whether it's a pet or wild, whether it can be safely contained or identified for observation/testing (never handle a wild animal).
- Call a health professional or your health department to decide together. Bring the details above.
- If treatment is advised, follow the professional treatment plan. Read what to expect after a bite (PEP) and find care with your local health department or a healthcare professional.
After Professional Assessment: What Indicated PEP May Include
If a clinician or public-health authority determines that PEP is indicated, here is the general CDC schedule so there are no surprises. Unvaccinated people get wound washing, one weight-based dose of HRIG at the start (infiltrated around the wound), and rabies vaccine on days 0, 3, 7, and 14 — a fifth dose at day 28 if immunocompromised. Previously vaccinated people get just two vaccine doses (days 0 and 3) and no HRIG. The vaccine goes in the arm, and most people tolerate it well, with mild soreness or a low-grade reaction being the usual worst of it. Keep every follow-up appointment on schedule. For the full walk-through, see what to expect after a bite (PEP).
Bottom Line
Professional rabies assessment considers the animal, the contact, local surveillance, and whether the animal can be observed or tested. The likelihood and response vary with the animal, contact, local surveillance, and whether the animal can be observed or tested. Because rabies is essentially untreatable once symptoms appear but preventable when appropriate post-exposure care begins before symptoms with timely PEP, err toward getting evaluated when the picture is unclear.

Which schedule applies?
When PEP is indicated, the US schedule for someone never vaccinated and without an immune disorder is wound care, HRIG once, and vaccine on days 0, 3, 7 and 14. Day 0 is the first vaccine date, not necessarily the exposure date. Qualifying previously vaccinated people receive vaccine on days 0 and 3 without HRIG. Immune disorders require specialist guidance, a five-dose regimen through day 28 and antibody testing.
Prior PrEP or PEP records, completion of required PrEP follow-up, immune status and any care received abroad must be reviewed by the treating professional. Do not use a dose count to decide your own treatment. WHO-supported schedules can use different routes and visit counts outside the US. Discuss treatment changes or delays with the treating professional.
