Examination of data sources listed by Gayer et al. (1) and recent reviews (2, 3) indicate that cholera occurs 1) in countries during war and civil unrest, as exemplifi ed by the latest outbreaks among displaced populations across northern Iraq; 2) in neighboring countries, where temporary camps accommodate masses of political refugees under poor conditions, such as those in eastern Chad near Darfur, Sudan; and 3) during the postwar period when large numbers of repatriated persons return home and consequently place undue pressure on an eroded and fragile national infrastructure, as evident in Angola in recent years.
