Summary: 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.

Cutaneous leishmaniasis (CL) remains a serious public health concern in Kerman Province, eastern Iran. This study was aimed to conduct a comprehensive review and highlights various aspects of CL in the province of Kerman. This article mainly focuses on the studies published in the past 26 years on CL in the province. Current data for the present status were obtained through the provincial health system. Bam was the most infected district (63.6%), followed by Kerman (24.7%) and other districts to a less extent. Leishmania tropica is the major causative agent (95.5%) of CL in Kerman province, however, L. major accounts for 4.5% of the total cases. Bam, Kerman and southern districts of Kerman province were purely anthroponotic CL (ACL), while Rafsanjan, Baft, and Sirjan showed both ACL and zoonotic CL (ZCL). In contrast, Orzoieh district was merely endemic to ZCL type. Phlebotomus sergenti was the main vector in ACL foci while Ph. papatasi was the major vector in the ZCL district of Orzoieh. Localized CL was the most prevalent form (80%) of the disease, while leishmaniasis recidivans was the most uncommon clinical manifestation (18.7%). Due to recent rises in CL disease both in regard of increases in incidence rate and expansion of the disease to new foci, and presence of various risk factors in the province, control measures and health strategies should have high priorities to help treat the existing cases and prevent the expansion of the disease to new areas.

Opium addiction and cutaneous leishmaniasis (CL) are endemic in different parts of Iran, particularly in Bam, where a massive earthquake occurred. This study was designed to compare the incidence rate and severity of CL cases among opium addicted and non-addicted individuals in south-eastern Iran. This study was carried out as a prospective cohort by active house-to-house visits of 1,481 habitants in Bam. CL cases were confirmed by smear and identification of Leishmania species was performed using nested-PCR. The data was analyzed by χ² and t-tests, using SPSS software and also Kaplan-Meier survival curve and long-rank test in Stata 11.2 and P<0.05 was considered as significant. A total of 904 individuals consisting of 226 opium addicted and 678 non-addicted individuals were followed-up for a period of seven years. The two cohorts were similar in terms of age, sex and place of residency. A similar pattern of incidence was observed among the two cohort groups. In contrast, the severity of CL in terms of the number, duration and the size of the lesions in opium addicted individuals was significantly (P<0.001) higher than non-opium addicted individuals. In conclusion, the present findings indicate that there is no relationship between the incidence of CL and opium addiction.

Background: Cutaneous leishmaniasis constitutes a major public health problem in many parts of the world including Iran. The primary objective of this study was to identify Leishmania species in endemic districts of Kerman Province, south-eastern Iran. Methods: This study was conducted by random sampling as cross- sectional descriptive between 2008 and 2010. Overall, 203 skin scraping smears were taken from the patients. Nested -PCR was performed to amplify variable minicircle fragments of Leishmania kDNA. Results: Barn was the most infected district (71.1%), followed by Kerman (14.7%), Jiroft (5.4%), Batt (2.7%), Sirjan (1.6%), Shahr-e Babak (1.5%) and others (3.0%). L. tropica was the most common species identified (194 cases, 95.6%), while L. major was found in only 9 cases (4.4%). Of 203 identified patients, all species in Barn (107 cases), Kerman (32 cases), Jiroft (16 cases) and Shahr-e- Babak (11 cases) were detected as L. tropica, whereas infected subjects in Baft and Sirjan showed L. tropica or L. major. Characterization of Leishmania species resulted in generation of 750 bp and 560 bp fragments, corresponding to those of L. tropica and L. major, respectively. Conclusion: L. tropica is the main species (95.6%) caused ACL in endemic areas of Kerman Province; however L. major is present in low level (4.4%).
