Since OPERATION Iraqi Freedom began in 2003, more than 700 US soldiers have been infected or colonized with Acinetobacter baumannii. A significant number of additional cases have been found in the Canadian and British armed forces, and among wounded Iraqi civilians. The Armed Forces Institute of Pathology has recorded seven deaths caused by the bacteria in US hospitals along the evacuation chain. Four were unlucky civilians who picked up the bug at Walter Reed Army Medical Center in Washington, DC, while undergoing treatment for other life-threatening conditions. Another was a 63-year-old woman, also chronically ill, who shared a ward at Landstuhl with infected coalition troops.
