PATHOGENS
- Sarcoptes scabiei var. hominis, an obligate parasite that burrows and reproduces in stratum corneum of the human skin.[6]
- Scabere, to scratch, from Latin. The mite lives its 14-day life cycle in the human epidermis. Adult mites cannot survive outside human skin for more than 2 to 3 days, and immature mites can survive for 1 week.[3]
- Pruritis is due to an intense hypersensitivity reaction that is generated by mite, ova, and excrement. Hypersensitivity and pruritis occur 2 to 6 weeks after the initial infestation.
