Vaccine-Preventable Disease Report

The Epidemiology Team at JCPH has created a thorough vaccine-preventable disease report -- focused on adults aged 45 and up in Jefferson County, from 2018-2022. The report tells the story of the importance of vaccines and how these preventable diseases have impacted our community.

This report is limited to reportable diseases, classified as probable or confirmed cases as documented in the Colorado Electronic Disease Reporting System (CEDRS). The graphs and tables focus on disease trends and burden of more prevalent vaccine-preventable diseases among the older adult population, including influenza, pertussis and respiratory syncytial virus (RSV). Although RSV was not a vaccine-preventable disease during the report period, with the recent approval of an RSV vaccine for adults aged 60 and older, it illustrates the disease burden of RSV in older adults.

Measles (Rubeola)

Measles is rare in Colorado, but cases and outbreaks still occur every year in the United States. Outbreaks can occur when people at risk for measles get sick and the virus spreads to communities with pockets of unvaccinated people. 

On December 19, 2023, an adolescent with unknown vaccination status tested positive for measles, one of the most highly contagious infectious diseases, while visiting Colorado from a country with an ongoing measles outbreak and nationally there have been 41 cases identified this year. 

Take control, you can protect yourself and the community against measles by making sure you are up to date on your measles, mumps and rubella (MMR) vaccine.
