Tickborne disease awareness and protective practices among U.S. Forest Service employees from the Upper Midwest, USA
Abstract Background: People with occupations that require them to spend time working outdoors in suitable tick habitats are predicted to be at an increased risk for tick-borne diseases (TBDs). However, few studies have assessed the risks of outdoor employees.Methods: We conducted a cross-sectional survey to evaluate the exposure to ticks and tick-borne disease infections among U.S. Forest Service employees in a high TBD incidence region of northwestern Wisconsin, and to examine their knowledge, attitudes, and practices (KAPs) regarding TBDs to help guide future education and prevention programs. Chi-square contingency tables, calculations of odds ratios, and logistic regression models were used to identify associations among self-reported employee factors, and the proportion of correctly answered knowledge questions, their ranked concern for TBDs, practicing preventive behaviors, and willingness to pay for protective measures. Results: Ninety-five employees completed the survey. Nearly all respondents (97%) reported recent tick exposure and their knowledge of TBD was high (median score: 80% correct). Fifty-nine percent of respondents had high concern for TBDs, and there was high adherence to conducting body checks for ticks (83% reported always doing them), but only moderate use of tick repellents (24% reported always and 60% reported occasionally using). High concern (OR = 3.4 [1.33- 8.91]) and a history of TBD (OR = 4.66 [1.21 – 17.89]) were positively associated with high practice adherence. Respondents suggested they would be willing to pay for personal protective methods and get a hypothetical vaccine for Lyme disease, but not community-wide efforts to control ticks. Conclusions: Our study provides evidence that U.S. Forest Service employees in Wisconsin represent a high risk group for TBD, and despite relatively high TBD knowledge and engagement in tick protection activities, targeted prevention programs are still needed to reduce their risks for tick bites.
