Understanding Rabies

Rabies is caused by a virus that animals and people can get through certain exposures to the saliva or nervous tissue from a rabid animal and is nearly always fatal without proper post exposure prophylaxis treatment. It is a  zoonotic virus, which means it can be spread from animals to people. Rabies is 100% preventable. In most cases, preventing rabies is as simple as ensuring adequate animal vaccination and control, avoiding contact with wild animals, and educating those at risk.

Rabies in Montgomery County

Every year in Montgomery County, an average of 40 animals are confirmed to be rabid by laboratory analysis. While most of these animals are wild animals such as raccoons, foxes, and bats, there have been several rabid cats in Montgomery County over the last 5 years.

The fact that rabies has been found in cats in Montgomery County is of great concern because it shows the disease migrating from the wild animal population into domestic animals. Once the domestic animal population is affected by rabies, it becomes far more likely that a human will be exposed. The best way to protect our community and our children is to ensure that all dogs and cats have a current rabies shot and are licensed with the County. Keeping domestic animals continuously vaccinated erects a barrier to keep rabies away from humans. Online pet licensing is also available.

Indicators of Rabies

Changes in an animal’s normal behavior may indicate rabies

  • Wild animals may act friendly
  • Domestic animal may act aggressive

Rabid animals may appear sick and may stagger when walking, drool heavily or suffer from paralysis

A nocturnal animal, seen outdoors acting normally during the daytime, is NOT an indicator of rabies

Bats and Rabies

The bat strain of rabies is present in our area and is often identified as the source of many human rabies cases nationwide. Bats have small teeth which may leave marks that are not easily seen. It is possible for a human to be bitten by a bat and not even know it. Certainly, if the bat is present in a room where a person was sleeping, a small child or elderly person was present, a person with disabilities was present or an intoxicated person was present, the bat should be tested for rabies due to the potential exposure. Any time a bat enters your homes living space you should call the Emergency Communication Section at 301-279-8000 so that an Animal Services Officer may respond to your home to assess the situation and capture the bat for rabies testing if necessary. If it was possible that a bite may have occurred, the bat will be tested for rabies.

Steps to Prevent Rabies

  • Only approach domestic animals that are known to you.
  • Avoid all contact with wild animals. It is unlawful to keep a wild animal as a pet.
  • Make sure that your dogs and cats have a current rabies vaccination and County license.
  • Keep dogs under control or on a leash. Keep cats safely indoors.
  • Don’t feed or water your pets outside. Even empty bowls will attract wild and stray animals.
  • Do not treat raccoons or other wild animals as if they were pets. Do not leave food out for raccoons, including leftover dog food, table scraps and large bird seeds.
  • Close off all entrances to chimneys, attics, garages or sheds which can provide a nesting site for raccoons. Install a chimney cap or heavy 26-guage wire screen on chimney openings and flues.
  • Bat proof your home in the fall and winter.
  • Use metal garbage cans that have secure lids. Plastic cans should have snap covers, but are not as secure. Ammonia can be sprayed or poured into plastic garbage bags to discourage raccoons from feeding.
  • Most human exposures to rabies occur when people attempt to rescue sick or hurt wild animals that, upon testing, are rabid.
  • Another frequent indirect exposure occurs when people handle their pets without gloves after the pet has had an encounter with a wild animal. It is considered possible for the rabies virus in saliva on the pet’s fur to be transmitted through a break in the person’s skin for up to 2 hours after the saliva has been deposited on the fur.
  • If you see a wild animal exhibiting abnormal behavior, call the police non-emergency number at 301.279.8000
