I have had it just about every year since I could walk, that would be 57 or so years. Sometimes just a minor case which I have right now, other times it has been really bad. One of the worst times I got it from cleaning about a dozen rabbits that had been buroughing through the roots in January. I do use straight bleach after I scratch it raw though I don't recomend that treatment, I can't count the times I have been up in the middle of the night scalding my hands in the bathroom and then going for the bleach. I took shots every year for several years in the spring and still got it just not as bad. I still keep a gal. of bleach in the shower and wipe down with it if I think I may have been close. I am going to order a new product monday (new to me) I just read about today "tecnu" 32 oz bottle for $16.50 from duluthtrading.com. Good luck
