It may be possible to acquire them might from infested bed sheets or clothing. There are little or no signs of the disease for 2-8 weeks. Mites copulate, increase in numbers and cause a localized to generalized itchy intolerable eruption. The disease is often misdiagnosed as eczema. Inappropriate treatment with topical steroids makes the disease worse. Many residents in a nursing home may be infested. Topical treatment with permethrin is effective. Resistant cases are treated with permethrin and oral ivermectin.
