Having been to one...I’d say NO, they don’t have nice hospitals. And they have drugs that are only used in Africa - no other place will allow them - according to the Dr. from Johns Hopkins that I luckily found.
You couldn’t make me go to Africa.
A few years ago, I took an injured employee to the hospital in Keneiba, Mali and had him admitted. The hospital was a windowless, circular mud hut with a thatched roof and only one door. The hospital had a dirt floor, was about thirty feet in diameter, and about fifteen patients were lying on straw mats on the dirt floor arranged in a circle around the wall.
I happened to arrive just as the doctor and two interns (you could tell they were doctors because they were wearing dirty white smocks) were making their rounds, and I watched them as they knelt by each patient to give them an injection all with the same needle. About every third patient, an intern would sharpen the needle, but no attempt was made to sterilize the needle. As an estimated forty percent of the local population was HIV positive at the time, it made that needle the most dangerous thing I have ever encountered.

African hospital care is all over the spectrum. Some we have used are fairly good. I've also been in some where the hygiene and care were worse than that received (personally) in a sandbagged aid bunker in Vietnam.
I've received very good treatment for both amoebic dysentery and Giardia in East Africa using a drug not approved by the US (tinidazole), but approved in many countries in the tropics.
For many diseases of the tropics, you will often get far better treatment from a well trained African doctor or long time missionary nurse than you would in a fancy US hospital that is not familiar with your problem. We returned to our remote Ugandan village after several weeks break in Kenya to find a woman who had fallen on a very hard, sharp broken tree branch which had pierced her abdomen and colon. This had happened a day or two prior to our return. She had a tight, distended abdomen and a high fever.
We drove her the two hours (25 miles) to the nearest bush hospital and left her in the care of a young Ugandan doctor. Two weeks later we drove out to the hospital to find her well & ready for discharge! I believe that this doctor had been educated at Makerere University in Kampala. We also have a friend who was a missionary nurse in Africa for many, many years, both in teaching and in mobile clinics in very remote areas. She would be my very first choice for treatment of African medical problems, short of major surgery.
