Interesting topic, this disease turns out to be more common than one might think.
I remember some years ago, working in a rural area, it was very common to see it.
And the purchasing power of these patients was very low, the cheapest option to treatment was a preparation of sulfur vaseline, which was prepared in the local drugstore, and in that way they managed to control this disease. It is an option when the economic means are not the best.
In addition, care at home of bed sheets, clothing, exposure to the sun, among other important things.
