In recent years, dust storms in Iran are considered a very familiar word for all people. The issue which has received widespread attention was a trend towards an increase of incidence of this phenomenon in our country. Because of its common frontier and proximity to the deserts of neighboring countries in western provinces, Lorestan experienced an average of more than 100 dusty days and 16 times higher than the global standard in recent years. The dust phenomena have many impacts on health, economics, and transportation of the country. Studies suggest that dust storms lead to increased respiratory illness. Particles size less than or equal to 10 microns’ diameter also increase the risk of death in children under 1 years of age, affect the functioning of the lungs and aggravate asthma and cause increased respiratory rate. Researches reveal that the rate of hospitalized patients' incidence due to pulmonary, respiratory and cardiovascular diseases increases exponentially once the dust phenomenon occurs. Using descriptive statistical method and simple linear regression and correlation relationships, this study analyzes the annual and monthly statistics of dust data of patients with asthma and pulmonary diseases referring at Shohada Ashayer Hospital of Khorramabad during 2004 -2012. The results show that there is a high correlation (higher than 80%) between two variables of dust with the number of patients with asthma and pulmonary and infectious diseases referring to hospitals and the frequency rate of these two variables during the spring and autumn seasons (63%). The statistics show the impact of dust on the exponential rate of patients with asthma and pulmonary infections referring to hospitals to the hospital.
