What to know
Tularemia is a nationally notifiable disease. Health departments investigate reports of possible cases submitted by healthcare providers and laboratories. They also classify the cases according to the national surveillance case definition, and report confirmed or probable cases to CDC to help track tularemia.
Case investigation and classification
Tularemia is a nationally notifiable disease, meaning state and local health departments report confirmed or probable cases to CDC to help track where and how often the disease occurs, identify outbreaks, and detect changes in risk.
Health departments can use the tularemia case investigation form developed by CDC to guide case investigations. Healthcare providers and laboratories report possible cases to state or local health departments.
Health departments investigate the reports and classify the cases using a standardized case definition established by the Council for State and Territorial Epidemiologists (CSTE).
The case definition includes clinical signs and symptoms, laboratory test results, and likely exposure to the tularemia bacterium. The national surveillance case definition for tularemia was last updated in 2026.

Reporting methods
Confirmed and probable cases of tularemia are reported to CDC electronically through the National Notifiable Disease Surveillance System.
State health departments are also encouraged to submit additional tularemia-specific information using One CDC Data Platform (1CDP).
