An outbreak of polio in Syria has officially spread into neighboring Iraq amid warnings scores of Iraqi children could be at risk. The disease was confirmed in a six-month-old baby boy in Baghdad late last month, marking Iraq’s first case in 14 years. Polio has paralyzed dozens of children in Syria where it emerged last year for the first time since 1999. The virus has been traced to Pakistan, where anti-polio workers have come under frequent attack after a polio vaccination campaign was used by the CIA to help find Osama bin Laden.
