Objectives: To describe a new emerging focus of anthroponotic cutaneous leishmaniasis (ACL) due to Leishmania tropica in rural areas of Dehbakry county, south-eastern Iran, after the earthquake of 2003.
Methods: House-to-house survey of 3884 inhabitants for active leishmaniasis lesions or scars. The diagnosis was confirmed by smears, cultures and identification of the parasite by polymerase chain reaction (PCR).
Results: All age groups were affected, although patients ≤10 years of age showed the highest rate of infection (P = 0.0001). The overall prevalence rate was 5.3%; 6.3% in females and 4.3% in males. Of 204 cases, 1.8% had active sores and 3.5% had scars, with a significant difference between the sexes (P = 0.005). 47% of the lesions were on the face and 77.9% had one lesion. The incidence rose gradually 2004-2005, but grew exponentially 2006-2008. Electrophoresis of PCR products indicated that L. tropica was the causative agent.
Conclusions: The current emergence was unexpected in this rural locality, where no previous history of CL was recorded. According to our knowledge this is the first report of a gradually establishing new ACL focus in rural communities after the 2003 earthquake.
