Trombidiosis, hay scabies, harvest scabies, autumn bite, autumn scabies, Giesinger bite, Sendlinger bite.
Skin infection caused by autumn mites, especially Neotrombicula autumnalis.
Primarily rodents (e.g. mice) act as a reservoir. At warm temperatures, the larvae can suck in contact with human skin. In the course of time they fall off again. In the course of time, a stabbing reaction is observed.
A few hours after exposure, erythematous wheals and maculae are visible, which in the course of 1-2 days develop into pruriginous, erythematous papules or seropapules with subtle hemorrhaging.
