defining characteristics

disease development
Eruption caused by tunneling of mite in stratum corneum that causes delayed type IV hypersensitivity response and diffuse pruritic eruption after 4-8 weeks

potential causes
Sarcoptes scabiei var. hominis
epidemiology
risk factors

Hospitals

Mineral oil prep? Mites with oval gray eggs and fecal pellets

Topical creams (scabicides)
treatment of fomites and close contacts
can use oral anti-parasitic if severe (ivermectin)
