A lot of countries in the developing world have existing health care resources, such as doctors or nurses, but managing them is a major problem in a state such as namibia or botswana where the population of a small city is spread out on a territory as large as germany. It helps if you can have a local, less qualified health care worker communicate with a remote specialist before either moving a doctor to the patient or the patient to the doctor. A medium to high bandwidth connection, eventually capable of video transmission helps a lot here.
