Communicable Diseases

In order to protect and promote the health of Cascade County, the Prevention Services division of the City-County Health Department (CCHD) works to protect the community from the spread of communicable diseases.

  • Investigates individual cases as well as outbreaks in a private and confidential manner,
  • monitors trends in particular diseases,
  • contains or controls the spread of these diseases,
  • and provides statistics to Montana DPHHS.

The Health Department does not provide treatment for communicable diseases, but will provide a referral to the Community Health Care Center or your healthcare provider for treatment.
Communicable diseases are those that are spread by touch, direct contact or even through the air. It is necessary for CCHD to track these illnesses to prevent the transmission of disease. Some of the diseases investigated by Prevention Services are Chlamydia, Hepatitis A, B, and C, as well as Giardia, Salmonella, and Campylobacter.

Reportable Diseasesare those that healthcare providers are required to report; CCHD is obligated by law to perform follow-up on all reportable diseases and conditions.
