​What is Rabies?​​​

​Rabies is an acute infection caused by a virus that is transmissible to all mammals, including people, pets, and live​stock.​​ However, most cases in North America occur in wildlife (~90%) and it is most commonly found in raccoons, skunks, bats, and foxes (often called rabies vector species). In Kentucky, raccoons, skunks, and bats are the main rabies vectors, or carriers of the disease. Rabies primarily affects the central nervous system and brain, progressing rapidly following a highly variable virus incubation period. Cases are typically 100% fatal once visible symptoms appear. The time to when an animal is infected to showing visible signs of the disease is called the incubation period and it is highly variable among wildlife species (typically 2-3 months) but may vary from 1 week to 1 year.

​​Disease Information​


Distribution of Rabies

Rabies is found on every continent. Some island nations, such as Japan and the United Kingdom, have completely eradicated rabies. There are multiple strains of the rabies virus that are associated with different species of wildlife who serve as hosts, or carriers, for the disease. Different regions of the US have different variants. As bats are capable of flight, the bat variant of rabies is distributed across the entire United States. In Kentucky, the rabies variants present are the skunk variant and the bat variant. The U.S. Department of Agriculture Animal and Plant Health Inspection Service National Rabies Management Program​ focuses primarily on the raccoon variant in the Eastern United States. The goal is to limit the spread of the raccoon variant and prevent its reintroduction into KY. The raccoon variant is a significant public safety issue as this variant is more commonly associated with more human and domestic animal cases due to their peri-domestic tendencies. In 2017, there was a raccoon variant detected in Virginia less than 10 miles from the Kentucky border, which prompted increased surveillance in Kentucky. 

Bats, skunks, foxes, and raccoons are native animals to Kentucky and play a key role in ecosystems. However, they can also pass on rabies to other mammals, including people. According to the Centers for Disease Control and Prevention (CDC), more than 90% of reported cases of rabies in the United States occurs in wildlife. Additionally, contact with infected bats is the leading cause of human rabies deaths in the United States. Keeping your distance and your pets away from these animals and other wildlife is a way to protect yourself from rabies and other diseases, while co-existing with wildlife. Vaccinating your pets against rabies is the best way to protect them against potential rabies exposures.​​

What are the symptoms of rabies?

Both wild and domestic animals with rabies can exhibit a wide range of possible symptoms (which can resemble other wildlife diseases, such as canine distemper. These include excessive aggression, agitation, or a lack of fear (especially towards people), incoordination, weakness, a head tilt, difficulty breathing or swallowing, excessive salivation, lethargy, and/or paralysis. Because rabies has a sudden onset and progresses rapidly, animals may still appear to be in good body condition. Rabies can also present with non-aggressive clinical symptoms like head pressing, excessive thirst, or fear of water. These non-aggressive symptoms are more common in livestock.

​How is rabies spread?​​​​

Rabies is spread through saliva and neural tissue (spinal or brain cord matter). It is not spread through blood, urine, or feces.

Rabies exposure to people and other animals occurs in the following ways:

  • A direct bite from a rabid animal.
  • A scratch from a rabid animal that breaks the skin.
  • Saliva or neural tissue (spinal cord or brain matter) from a rabid animal coming into contact with a wound or a break in the skin.
  • Saliva or neural tissue (spinal cord or brain matter) from a rabid animal coming into contact with the eyes, nose, or mouth.
In some cases, it is possible for rabies to be transmitted through water if a rabid animal was drinking out of a water bowl shortly before an uninfected animal drinks from the same bowl. 

The rabies virus is not very hardy in the environment and quickly becomes deactivated. The virus particles become non-infectious if it dries out and is exposed to sunlight. Different environmental conditions affect the rate in which the rabies virus become inactive but it typically can only survive a few hours at room temperature.


How is rabies diagnosed?

​Rabies can only be diagnosed post-mortem. There is no live test for rabies. Symptoms are used to make a tentative  diagnosis and is confirmed by post-mortem testing of the brain tissue in suspected cases. Testing for rabies cannot be performed on a  live animal.

Quarantine and observation periods are only recommended for suspected cases in domestic animals. As there are controlled studies that provide reliable data related to acceptable quarantine times for these species. No such quarantine recommendations exist for free-ranging wildlife species due to the variable incubation period. It is recommended that all rabies-suspect wildlife should be euthanized in a manner that preserves the head so that the animal can be tested for rabies.


How is rabies treated?

There is currently no treatment or cure for rabies and cases are typically 100% fatal once visible symptoms appear in wildlife, pets, livestock, and people. However, rabies is preventable through vaccination. This is an effective option for people at risk of exposure (veterinarians, wildlife biologists and rehabilitators, animal control, etc.), pets, and livestock – not for free-ranging wildlife. ​

The USDA APHIS National Rabies Management Program has the only approved vaccine for use in wildlife. These oral rabies vaccine baits are distributed in targeted locations to control the raccoon variant, specifically in the Eastern United States, and along the border with Mexico in Texas, to prevent the canine rabies variant from moving up from Mexico. These vaccines are only used by government agencies conducting rabies control programs for specific variants in target locations and have been deemed a success. ​

People should seek medical attention and guidance regarding postexposure prophylaxis (PEP) following a rabies exposure. Learn more about PEP.​

Does rabies pose a risk to people or other animals?

​​Rabies is transmissible to all mammals, including people, pets, and livestock. It is 100% fatal if left untreated. Vaccines are available for pets and livestock and should be vaccinated and revaccinated to boost their immunity against this disease regularly. 

According to the CDC, bats are the leading cause of rabies deaths in people in the United States. If you have been bitten or scratched by a bat, or if you woke up in a room with a bat, contact your healthcare provider immediately to determine your risk for rabies and to seek appropriate care. Bat bites and scratches are small and can be unnoticeable. It is important to take proactive measures to protect yourself from rabies exposure.

Bats are typically most active at night but do fly around dusk. Sometimes juvenile bats may fly during the day, dwell in and around homes, be found on the ground, or climb instead of fly. This is often normal behavior as they develop into adult bats. However, its important to always remain cautious around bats regardless. If a bat is flying erratically during the middle of the day, acting strange, found on the ground and unable to fly, it may have rabies and should be avoided as a precaution. Report observations of sick or dead bats​ to Kentucky Fish and Wildlife.

How can rabies be prevented?

The virus that causes rabies is 100% fatal once symptoms appear and can infect all mammals, posing a significant risk to people, pets, livestock, and wildlife. The following are tips that can protect you, your pets, and others against rabies:

  • Keep pets current on all vaccinations, including rabies.
  • If your pet has come into contact with, or has been bitten by wildlife, contact your veterinarian.
  • Do not touch, hold, or handle wildlife. If you are bitten by a wild animal, it must be euthanized and tested for rabies, even if the animal wasn't showing any symptoms of the disease.
  • Do not keep wildlife as pets. It is illegal to keep rabies vectors as pets in Kentucky.
  • Avoid feeding wildlife.
  • Do not leave pet food outside as the food can attract raccoons, skunks, and foxes. These animals can carry rabies and it puts yourself and your pets at risk for coming into contact with infected saliva or a rabid animal.
  • Exclude wildlife from your dwellings.  Seal holes and other entrance ways so wildlife do not come into homes or businesses.
  • Wildlife are wild animals. We all have a part to play in allowing them to live their wild lives. Appreciate wildlife safely by observing them from afar. ​​
