Background & Objectives : Visceral leishmaniasis is an important endemic disease in Iran and Meshkin shahr County is the most important foci of visceral leishmaniasis in Iran. The aim of this study is the survey of recent changes in epidemiological patterns of visceral leishmaniasis in Meshkin Shar area during 12 years.   Methods : This is a descriptive retrospective study. Records of 193 cases with confirmed kala-azar disease were reviewed in the period of 2001-2012. Data collected from files and were analyzed using descriptive statistics and SPSS v.15.   Results : From 193 patients with confirmed kala-azar disease, 85% were resident in rural and 15% in urban areas. Among of these patients, 43% were female and 57% male. About 66% of patients were under 2 years old, 23% in age group between 2-5 years and 11% above five years. Among four parts of Meshkin Shahr County, in the first five years of the study, the most cases of the disease were from the central part, but in second six years the most cases were from the west part of this county and in latest year (2012) it has been coverted .   Conclusions : Incidence of kala-azar was decreased during last 12 years.
