text: if u dont wash, what is the sores that form on the skin? i met someone the other day who said he only washes himself once a week.  he had red dots/sores (skin flakes off top of dots) all over his skin/body.  he said it was bed bugs.  what would this be? (looks like measles or something)  if someone does not wash themselves - do sores form? what is the scientific name for this skin condition? what treatment?  i have to tell him what he should do about it next time i see him. it looks terrible.  (he does not use drugs or alcohol - just does not wash) he could have anything. scabies, bedbugs,ezcema, dermatitis,and psorasis.  bedbugs, scabies are highly contagious..so be careful that you don`t catch it!  bedbugs usually comes from not being clean with your mattress.
