“Kenya, which has declared a polio outbreak a public emergency, vaccinated more than five million children to curb the spread of the viral disease after a spate of cases in eastern Africa, the United Nations said,” Bloomberg reports. “While Kenya has confirmed 14 cases of polio since May 14 when the first case in almost three decades was detected, none have been recorded in the past four months, according to [UNICEF],” the news service writes, noting, “The outbreak in the region has been the worst in neighboring Somalia, where vaccination efforts have been prevented by a more than two-decade-long civil war” (Doya, 11/26).
