Iraq is a country which is being heavily affected by climate change, as well as experiencing a decrease in water for irrigation as a result of Turkish daming of the Euphrates. As a possible result, dust stroms are increasing in duration and severity. We intend to review Ministry of Health health information system data on consultations for respiratory infection on both inpatient and outpatient bases, and review atmospheric dust data from the Meteriologic Department to look for associations. These will be at the governorate level. In addition we will interview key informants at large hospitals knowledgeable about outpatient, emergency department and inpatient admission trends in Baghdad.
