NOTE: A surveillance case definition is a set of uniform criteria used to define a disease for public health surveillance. Surveillance case definitions enable public health officials to classify and count cases consistently across reporting jurisdictions. Surveillance case definitions are not intended to be used by healthcare providers for making a clinical diagnosis or determining how to meet an individual patient’s health needs.
An illness characterized by several distinct forms, including the following:
Clinical diagnosis is supported by evidence or history of a tick or deerfly bite, exposure to tissues of a mammalian host of F. tularensis, or exposure to potentially contaminated water.
A clinically compatible case with laboratory results indicative of presumptive infection
A clinically compatible case with confirmatory laboratory results
The 1996 case definition appearing on this page was re-published in the 1999 CSTE position statement 1999-ID-6 and the 2009 CSTE position statement 09-ID-66. Thus, the 1996, 1999, and 2010 versions of the case definition are identical.
