Rabies in Colorado
In Colorado and throughout the United States, many different wild animal species can carry rabies. Skunks and bats are the most significant sources of rabies in Colorado, but other animals such as dogs, cats, horses and livestock, can become infected with rabies through contact with wild animals. Small rodents and rabbits do not usually carry rabies.
Rabies is becoming more common in wildlife along Colorado's Front Range, placing both humans and animals at risk for this deadly disease.
Rabid animals usually show abnormal behavior, such as aggression, confusion or lack of fear of people.
Contact with infected wild or domestic animals places you and your family at risk for rabies infection. Immediate medical treatment is required if a person or domestic animal is exposed to rabies.
Rabies in humans is 100 percent preventable through prompt and appropriate medical care. Your health provider, possibly in consultation with your state or local health department, will decide if you need the rabies vaccination series.
