In his “Africa in Transition” blog, John Campbell, Ralph Bunche senior fellow for Africa policy studies at the Council on Foreign Relations, examines the reemergence of polio in the Horn of Africa, noting the WHO in April “reported the new presence of wild polio virus type 1 (WPV1) in the Banadir region of Somalia” and another “confirmed case of polio at Kenya’s Dadaab refugee camp” in May. “This most recent polio episode highlights the importance of thorough and ongoing vaccination campaigns,” he states, adding, “The governments of Somalia and Kenya and the relevant U.N. agencies are moving quickly to respond.” However, he notes, “As in so many other areas, governance and security are proving to be essential to the elimination of a disease” (6/5).
