I have a real life complaint about this - my FILs memory care had an outbreak of scabies from a new resident. In addition to treating all the bedding, mattress,clothes, they had to apply a treatment cream, head to toe for every patient (some of which are not compliant) twice and soothing cream every other day between treatments. It was a month total of daily applying cream to every patient (20).
Ivermectin would have been so much easier. Plus my FIL who is a very private man, was humiliated by the whole ordeal.
Good gosh, I see completely how that would be a problem. Sigh. Medicine sure isn’t perfect...
