The high risk of acquiring tick-borne diseases by outdoor workers is well documented. Workers
most at risk include, foresters, park rangers, land surveyors and other outdoor workers have
frequent exposure to tick-infested habitats. Many North Carolina state employees with outdoor
occupations report multiple tick bites each year, which indicates that existing tick
preventive strategies may be ineffective. The principal goal of this study is to assess
whether the use of long-lasting permethrin impregnated uniforms can reduce the number of tick
bites sustained by North Carolina outdoor workers.
