Disease Surveillance


Tri-County Health Department investigates infectious (contagious) diseases that can be spread in a variety of ways: from person-to-person, through contact with animals, or through eating contaminated food and water. This includes serious diseases such as E. coli, Salmonella, hepatitis A, meningitis, and whooping cough (pertussis).

Think of us as disease detectives. When certain diseases are reported to the health department, we work hard to determine where a person got sick and try to prevent further spread of illness. We also work to prevent the occurrence of diseases in our communities through education of our residents.

Reporting Diseases

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.

Reporting Outbreaks

Tri-County investigates disease outbreaks in long-term care facilities, child care facilities, restaurants and other group settings. We attempt to identify the cause of the outbreak and immediately put control measures into place. To report an outbreak or suspect outbreak call 303-220-9200 and ask for communicable disease.
