According to Dr. Frank Glover, a medical missionary speaking on ABC's "This Week" along with former U.S. Ambassador to the Republic of the Congo Robin Sanders. Americans should be concerned about the west African Ebola outbreak, but should not be panicked. 

Glover says the health system in Africa has collapsed, but the United States has facilities and technology to deal with the potentially-deadly virus.

Sanders says this particular outbreak is different from other outbreaks because the population density of affected countries is more dense than in the past.
