Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hypothesis: Does treatment of lower extremity clothing with permethrin prevent Lyme disease?

This is a double-blind, randomized clinical trial using permethrin treatment of clothing to prevent Lyme disease.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a double-blind, randomized clinical trial using permethrin treatment of clothing to prevent Lyme disease.

Subjects (N=200) will be recruited from camp staff to participate in the study and screened by inclusion and exclusion criteria.Qualifying subjects will be randomized to either the treatment (N=100) or non-treatment arm (N=100).

Subjects in the treatment arm will have their scout shorts, pants, and socks sprayed with 0.5% permethrin and allowed to dry. Subjects in the non-treatment arm will have their scout shorts, pants, and socks sprayed with water and allowed to dry.

Subjects will then be followed over the summer camping season to see if they develop Lyme disease. At 70 days, all subjects will have their Lyme titers rechecked to ensure that all cases of Lyme disease were documented.

Following the 70 day visit, there will be an assessment of the final study outcomes.
