Inside Kenya's Ebola defences as seven Americans enter quarantine

Instead, that role has fallen to Kenya, where seven American aid workers are now completing a mandatory 21-day quarantine after working in Ebola-affected areas of eastern Democratic Republic of Congo.

Their arrival has reignited debate over Kenya's role in regional outbreak preparedness and raised a question that extends far beyond the fate of the seven Americans: If Ebola crossed Kenya's borders tomorrow, is the country ready?" The aid workers, all returning from the Democratic Republic of Congo (DRC), where they were involved in responding to the world's largest recorded outbreak of the Bundibugyo strain of Ebola, have no symptoms and have not tested positive for the virus.
