At one time, Cuba (pre-Revolution) had the best doctors (most US trained) and medical care in Latin America, but if you don’t replace equipment for 50 years and your doctors only get 2 years of training, you end up with what’s in the picture. Oh, you do setup one or two hospitals for tourists and reporters that look decent, but the average Cuban sees the real thing.
