Eastern Equine Encephalitis Virus Surveillance and Control Guidelines

About These Guidelines

Comprehensive CDC guidelines for arbovirus surveillance programs in the United States were published in 1993 (CDC 1993). These guidelines detailed best practices for surveillance and control of eastern equine encephalitis (EEE), La Crosse encephalitis (LAC), St. Louis encephalitis (SLE), and western equine encephalitis (WEE). In the several decades since the guidelines were published, EEE has emerged as a vector-borne disease of increasing public health concern due to multiple outbreaks of neuroinvasive disease and the potential for further expansion of EEE into new U.S. regions. Additionally, knowledge about EEE epidemiology and transmission ecology has greatly expanded. The objective of this guidance is to consolidate new knowledge and describe how this can be used to better assess EEE virus activity and mitigate its public health impact. These guidelines are meant for state and local public health officials and mosquito control personnel to aid them in the surveillance and control of EEE.
