[Trombiculiasis, and epidemic of prurigo caused by mites].

In four villagers parasitic prurigo caused by the autumnal chigger (Neotrombicula autumnalis) was diagnosed. The clinical picture consisted of intensely itchy, erythematous papules, at sites where clothes fitted tightly or in body folds. Further investigation in the village revealed that in 16 of the 48 homes at least one person in the preceding two months had suffered from prurigo possibly caused by the autumnal chigger. The characteristics of the parasite, the clinical picture, treatment and prevention are discussed.
