The leishmaniases are among the most important emerging and resurging vector-borne protozoal diseases, second only to malaria in terms of the number of affected people. Like malaria, the leishmaniases can be caused by infection with any of several species of parasites belonging to the genus Leishmania and transmitted by sand flies.The purpose of thisinvestigation was to determinethe atmospheric-oceanic Southern Oscillationpattern, asa factorinclimatic conditionsof the country, theincidence ofleishmaniasis, in the city ofQasr-e Shirin. Inthisregard, theSouthern Oscillationpatterndata was recieved for theperiod1369 to1391fromthe University ofEast Angelia.The data of annual CL incidence in Qasr-e Shirin were collected from the national and international reports of CL incidence in Iran. To evaluate the effect of hot and cold phases of the macro-scale weather pattern, the outbreak data based was separatednbased on the monthly phases and the significance of difference between warm and cold ENSO phases of outbreak data were studied by independent with double-sided t_studen test. The results showed that the annual incidence of leishmaniasis in the city of Qasr-e Shirin data, is significant only inApril and March months. The running of Independent two-sided t test on two series of cases based on the separation of cold and warm phases of ENSO Was showed that in April and March in the years since phases with ENSO (La Nina) are The average of outbreaks are the average is higher than the years in April and March are warm phase of ENSO (El Nino) is dominant in Qasr-e Shirin city.
