Primary outcomePrimary: Work Related Tick Bites — 265; 780 tick bites — p=0.004
Summary
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.
