The Malaria is endemic disease that has been broken out from old times in Iran. The outbreak of this illness is affected by economic, social and cultural problems, especially environmental conditions. In this study, It correlation between annual changes of patient cases and SOI index in Iran during 1990- 2007 period and, monthly changes for Chabahar city during 1382-l 1387, have been analyzed. In this regard, values of annual rain in Iran during a statistical period (1990-2007) and monthly and annual rain of Chabahar during (1382-1387) were used that obtained from Iran meteorological organization and meteorology station of Chabahr respectively. The monthly and annual SOI index data was taken from NOAA. The results showed that SO accident negative phase (Elnino), which accompanied with increasing precipitation in this country, is matched by decrease of Malaria cases and that in years which positive phases (Lanina) occurred, Malaria cases increased. But in Chabahar city, this situation is inverse. This means that, negative and positive phases of Southern Oscillation are accompanied with decreasing and increasing rain respectively. So, Elnino increased malaria cases and Lanina decreased it in Chabahr.
