Disease Surveillance Data

Public Health Surveillance is the collection, investigation and distribution of data about illness and death. This surveillance helps prevent and control disease and is used to protect and improve the health of the public.

In Washington State, healthcare providers, healthcare facilities, laboratories, veterinarians, food service establishments, child daycare facilities, and schools are legally required to notify public health authorities at their local health jurisdiction of suspected or confirmed cases of selected diseases or conditions. These are referred to as notifiable conditions. Below are the annual notifiable conditions surveillance report for region 2 (Clallam, Jefferson, and Kitsap County). For Kitsap Respiratory Illness Reports, please visit our Influenza Updates page.
