just ship the actual doctor.
Do you know how many doctors they have in America? How about in Liberia?
According to the CIA World Factbook, in 2008 the U.S. had 2.4 doctors per every 1000 people. In Liberia, they had 0.01 per 1000, but that was before ebola killed 40 of their 120 physicians. Volunteer doctors have helped a little, but not too many want to risk their own lives in such a hot zone. The need is almost beyond comprehension.
Oh, and of those 80 remaining doctors, how many do you think specialize in surgery, and have hours in their day to operate on you? How many specialize in the kind of surgery you may need at that moment?
You can't 'just ship the actual doctor' any more than you can send them a stack of gold bars. There aren't enough who have time or the inclination to go.
