Communicable Disease Response and Control

The Whatcom County Health Department relies on healthcare providers, laboratories and hospitals to report certain diseases to us.  While clinician reporting is our best source of information, it has been estimated that as few as 10% of the currently reportable infectious diseases are actually reported.  Only by prompt reporting of confirmed and suspect conditions can we protect public health in our community.

A list of reportable conditions can be found at: Notifiable Conditions Poster

Communicable disease nurses are available at (360) 676-4593 to consult with healthcare professionals regarding testing and prevention of infectious diseases.  If you wish to report a notifiable condition, please call our 24-hour report line at (360) 738-2503.

About the Communicable Disease Program

Health care providers are required by Washington law to report certain medical conditions that have a public health impact.  The Communicable Disease Program focuses on preventing or limiting the spread of certain communicable diseases.  This is achieved through surveillance, case investigations, contact follow-up, and consultation with local health care providers.  The data gathered from this reporting is also used to plan health services in the future.
