Tick-Borne Diseases: Department of Health, https://tickencounter.org/prevention/permethrin, Rhode Island and the University of Rhode Island has a lot of information in Lyme disease. I'm not out in the woods much any more but during my hiking and backpacking days I followed the advice given for the use of Permathrin on clothing with reapplications as called for. So far no lyme disease but I still have a good supply in a spray bottle if needed for Prevention.

The well known author, Amy Tan contracted Lyme disease and of all places, during a trip to Lyme, Connecticut. She had a lengthy and detailed chapter about this in a book whose title I don't now remember. Several points in that chapter stand out. First, diagnosis is tricky with false results, at least when the book was written. Second, not all MDs are that competent at diagnosing Lyme. The same difficulty in diagnosis was written about by an MD from Hartford whose book was all about the art and science of diagnosis. Lastly, for some people the disease can have life long serious consequences.

We cyclists are frequently stepping into the woods for nature breaks. If you have not yet given much thought to deer ticks and Lyme, it is time to begin doing that.
