Since then, those patients have started receiving post-exposure treatment.

“We’re concerned about the growing number of cases among other animals such as raccoons and cats,” Mark E. Wallace, MD, MPH, Executive Director of the Weld County Health Department said.

– Leave orphaned animals alone. Baby animals often appear to be orphaned when they are not. The parent animal may not return if people are too close.
– Do not feed, touch or handle wild animals and be cautious of stray dogs and cats.
– Have dogs, cats, horses, and livestock vaccinated regularly by a licensed veterinarian.
– If you do find a wild animal that appears to be sick, injured or orphaned, contact your local Animal Control Officer, Colorado Parks and Wildlife, or a local veterinary office before attempting to move it.
