Objective: To update current situation of the cutaneous leishmaniasis(CL) in Kazerun County,southwest of Iran and to analyze the epidemiological aspects of the disease during 2005-2015,Methods: Data on CL were obtained from the Health Center of Kazerun County,and then were analyzed and mapped using SPSS and Arc GIS 10.3,Results: A total of 700 cases of CL were recorded during the study period with an overall decreasing trend from 2005 to 2015,More than 60% of the patients were inhabitants of rural areas and males were infected more than females,Although there was not a significant difference between gender,job categories,residence and CL infection(P>0.05),age groups were significantly different(P0.05),Most of the acute lesions were found to be present on the hand,leg and face,respectively,The average CL incidence in the study area was calculated as 24.9/100 000 population,A hot spot for the disease was found in southern part of the area(P<0.05),Conclusions: This study revealed that CL is present in Kazerun country,Thus,effective monitoring and sustained suveillance system is crucial in counteracting the disease,and if possible,to eliminate it.

Asian Pacific Journal of Tropical Biomedicine 2019年第5期9卷 181-187页

Objective: To determine the spatial distribution and infection rate of sand flies as vectors of Leishmania parasite in Ardabil province, northwest of ***: This was a descriptive cross-sectional study. The sand flies were collected from 30 areas in all 10 districts of Ardabil province during 2017. The specimens were caught using the sticky traps. The head and genitalia of sand flies were separated and mounted in Berlese solution for microscopic identification. The Geographical Information System ArcMap10.4.1 software was used to provide the spatial maps. Results: A total of 2 794 sand flies specimens were collected and 22 species of sand flies were identified from the two genera: Phlebotomus and Sergentomyia from Ardabil province. The highest frequency was found in Phlebotomus papatasi(23.7%) followed by Phlebotomus kandelakii(13.0%). The promastigote form of Leishmania infantum parasite has been reported from the three main vectors of visceral leishmaniasis(Phlebotomus kandelakii, Phlebotomus perfiliewi and Phlebotomus tobbi) from Ardabil province, where the spatial distribution map of these visceral leishmaniasis vectors was prepared. Some important species of sand flies such as Phlebotomus kandelakii, Phlebotomus perfiliewi and Phlebotomus tobbi were reported and identified as main and probable vectors of visceral leishmaniasis in Ardabil. Conclusions: According to the Geographic Information System based maps, the frequency of the sand flies as leishmaniasis vectors, the leishmania parasite infection rate and the prevalence of the disease in the central areas of Ardabil province are higher than in other areas in Ardabil province.
