West Africa Ebola Travel Ban

The Obama administration consistently refuses to impose a travel ban on those West African countries with the Ebola epidemic.  These countries are predominately Muslim.  Sierra Leone is 73%, Guinea is 85%, Nigeria is 50%, and Liberia is 13%.  Muslim treatment of the dead according to Sharia requires washing the body by relatives in preparation for the funeral.  This religious custom spreads the Ebola disease.

ISIS recruits fighters for their cause from many places in the world.  Do they recruit from these West African countries?  Or, do they have a travel ban to keep people from these West African nations out of their strongholds in Syria and Iraq?

I suspect a Muslim or anyone from one of these affected countries would not be welcome by ISIS, and in all probably would be quickly exterminated without benefit of Sharia custom.

Is ISIS smarter than Obama?
