In 2002, Wisconsin public health officials were notified of two cases of febrile illness in workers at a commercial turkey breeder farm (farm A) in county A. The Wisconsin Division of Public Health (WDPH) initiated an investigation that found a high prevalence of West Nile virus (WNV) antibody among farm A workers and turkeys. An associated high incidence of febrile illness among farm A workers also was observed. This report summarizes the results of this investigation, which indicate possible nonmosquito transmission among birds and subsequent infection of humans at farm A. Because the mode of transmission in this outbreak is unknown, turkey handlers should take appropriate precautions, including use of DEET- containing mosquito repellents, protective clothing and gloves, respiratory protection, and proper hand hygiene. Suspected occupationally acquired WNV infections should be reported immediately to local and state health departments. During November 2002, WDPH and the Wisconsin State Laboratory of Hygiene (WSLH) confirmed that two ill residents of county A had been infected with WNV. Before these reports, only one human WNV infection had been reported in this county. Both persons worked at farm A and had febrile illness with rash during late September-early October. These human illnesses occurred after a suspected fowl pox outbreak among farm A turkeys in September. Workers were concerned the pox outbreak might be associated with their illnesses.
