Communicable Disease Information and Prevention (Non-COVID19)

Grand County Public Health responds to infectious disease outbreaks and other local emergencies with public health implications. Communicable disease prevention, investigation, and control is a core public health service in Colorado. The majority of reportable diseases/conditions require some type of public health investigation, mainly related to controlling further disease spread. Follow this link for updated Communicable Disease information from Colorado Department of Public Health and Environment.

Many diseases must be reported by the medical community (hospitals, physicians, laboratories) to local and state health departments. A list of diseases and medical conditions which must be reported is available on the Colorado Department of Public Health and Environment website.
