Osteoarcheological and biomolecular evidence of leprosy from an 11-13 century CE Muslim cemetery in Europe (Orosháza, Southeast Hungary).

Orosháza site no. 10 (Southeast Hungary) contains the partially excavated archaeological remains of an 11-13 century CE Muslim merchant village and its cemetery located in close proximity to Christian villages of the same era. The skeleton of a young woman (grave no. 16) from the last phase of the cemetery use was identified with rhinomaxillary lesions associated with lepromatous leprosy. The right parietal bone also exhibited signs of cranial trauma, possibly caused by symbolic trepanation, a well-known ritual practice in the 9-11 century CE Carpathian Basin. The retrospective diagnosis of the disease was supported by ancient DNA analysis, as the samples were positive for aDNA, shown to be of genotype 3. Contrary to the general practice of the era, the body of the young female with severe signs of leprosy was interred among the regular graves of the Muslim cemetery in Orosháza, which may reflect the unique cultural background of the community.
