All of my kids had them 2 years ago. Luckily with a lot of perseverance and making sure that I boosted their immune systems daily with probiotics, we were completely free of them within 2 months. I changed linen daily (towels and changed sheets), they showered instead of bathed. I used to cover the ones on their knees (mine had them on their knees as well as around their mouth and on their bottoms) after applying Iodine antiseptic on them and for their bottoms I used Colloidal Silver to spray on it. We've not had them back since. But yes, some people do have them for years and it can be very hard to treat at times.
