How much time have you got for an answer?
If ignorance equals stupidity, one can be very stupid. Ignorance and superstition rule in West Africa. That's why they are in the situation they are in.
There have been reports of villagers killing education teams that are trying to inform people of how ebola is transmitted. They don't want to hear it. Red Cross workers dealing with dead bodies have been attacked.
People in that part of the world are fairly casual about hygiene, sanitation, what they eat, disease, and human life in general. This guy is probably a semi educated typical West African. Ride in a cab with a woman dying of ebola one day and hop on a plane to Dallas to visit your relatives the next day. What could possibly go wrong?
Yeah, they're very much like the half of our population that supports Odinga.
Stupidity rules here, too -- for the moment.
