(See our Chronic Disease page for information on heart disease, stroke, cancer and diabetes.)

Think of us as disease detectives. In an outbreak, the disease control staff trace the cause of an illness to its source, determine who else is at risk, and put control measures into place - such as immunizing the at-risk population or issuing glove orders for restaurant workers.

By law, certain diseases that have public health consequences must be reported to public health agencies from health care providers and laboratories in order to keep the illness from spreading.

Tri-County Health Department also tracks infectious disease data across the region through the Colorado Electronic Disease Reporting System (CEDRS). CEDRS is a confidential early-warning system that allows us to follow disease trends and put urgent prevention measures into place in order to protect our community.
