"It's relatively rare in Colorado. We had one horse with rabies last year in September and again this year, so in a short time period we've had two cases of rabies and we haven't seen any [horse] cases of rabies in Colorado in over 25 years," Assistant State Veterinarian Nick Striegal said.
The Department of Agriculture is asking livestock and pet owners to discuss animal health with their local veterinarians.
"Animal owners need to be aware that rabies is transferring from one species to another and they should monitor their animals for symptoms," State Veterinarian Dr. Keith Roehr said.
According to the Colorado Department of Public Health and Environment, there were 103 rabies cases in 20 Colorado counties in 2009.
Officials say one of the cases include a horse. As of April 12, a total of 28 animals have tested positive for rabies in Colorado, according to the Colorado Department of Agriculture - most of those cases are from skunks.
State health officials also say rabies can be passed from animals to humans.
"It is very important for people to be aware of rabies. Once an animal gets rabies or a human gets rabies, it is a fatal disease," Striegal said.
Prompt medical treatment can prevent the virus from progressing.
Rabies is a viral disease infecting the brain and central nervous system. It is primarily spread through the bite of rabid animals.
