Papillomavirus infection in humans and dromedary camels in Eastern Sudan

Cases of wart-like lesions in humans and dromedary camels occurred in eastern Sudan in 2015 were described. Involvement of papillomavirus (PV) in causing these cases was affirmed by PCR and immunoperoxidase test. Mostly, the lesions were observed on the skin of the chest and forearms in addition to lips and mandible. Sequence analysis revealed Camelus dromedarius PV types 1 and 2 genotypes as the causative genotypes. We also observed cases of wart-like lesions on hands and legs of two herders attending the infected camel herd. Partial genome sequencing revealed human PV type 2 in one of the two human samples providing no indications for interspecies transmission of camel PVs, yet provides, for the first time evidence of active circulation of this virus in eastern Sudan.
