Talk about selective editing, Ebola was less a problem for Nigeria for this epidemic; there were only 19 well contained cases there. It was a similar situation in Senegal. The very next paragraph after the single sentence about Nigeria and Senegal states this:
More than 4,500 people have died from the virus in West Africa, according to the World Health Organization, which said the region is still suffering from "widespread and intense transmission" because patients don't have access to adequate health care. There's a social crisis, too. Orphans of victims are often abandoned, their relatives terrified of taking them in.
Widespread and intense transmission still raging in Guinea, Sierra Leone and Liberia.
Good news for Texas, Nigeria and Senegal where outbreaks were quickly contained, but continuing bad news for West Africa which still threatens the rest of the world in this age of global commerce.
