Disease Highlight: Measles - Be Prepared!
What you need to know:
  • Ten jurisdictions nationwide are currently experiencing outbreaks of measles, defined as three or more cases.
  • As of 6/13/19, 1,044 cases of measles have been identified in 28 states in 2019. These jurisdictions include: New York (Rockland County, New York City), California (Butte, LA, and Sacramento Counties), Michigan, Georgia, Maryland, Pennsylvania, and Washington.
  • Be especially aware of patients with measles symptoms traveling to Colorado from these states.

  • Read the school and childcare letters TCHD distributed on 5/9/19 located on the School Wellness Page.

World Zoonoses Day, July 6th, 2019
On July 6th, help bring awareness to zoonotic diseases and the relationship between humans and animals. As of 6/14/19, TCHD has identified five skunks positive for rabies in 2019. Colorado has had 73 rabies positive skunks, 10 bats, 2 raccoons, one dog, one fox, and a cow.

TCHD works closely with providers, hospitals, and animal control partners to assess human and domestic pet exposure to rabies reservoir species. Animal bites are a reportable condition , and must be immediately reported to public health. According to the CDC , in the United States, wildlife rabies, especially in bats, continues to pose a risk to humans. Travelers also might be exposed to canine rabies in countries where the disease is still present; increased awareness of rabies while traveling abroad is needed. Vaccinating pets, avoiding contact with wildlife, and seeking medical care if one is bitten or scratched by an animal are the most effective ways to prevent rabies. Understanding the need for timely administration of PEP to prevent death is critical.

If you have a patient needing rabies post-exposure prophylaxis (PEP), please call TCHD prior to administering any PEP. 303-220-9200 or after hours, 720-200-1486.
