that border Iran—and thus can potentially affect the health of its people—include Afghanistan, Pakistan, Turkmenistan, and Iraq (see Figure 2-1). In his presentation, Ardalan provided background information on surveillance in Iran, described the design and preliminary results of a surveillance system pilot project, identified the limitations and strengths of the surveillance system, and proposed future steps that could improve the surveillance.
