In the long run, a research pathologist could probably do the most good in a developing country. Same with research in infectious disease.
Infectious Disease
The Global Health Forum for Health Research has shown that only 10% of the world health expenditure on health R&D in spent on health conditions that represent 90% of the global burden of ill-health. aka "10/90 gap". Much of the poor health in developing countries is due to water-borne illness and infectious diseases. As infectious disease is a subspecialty of internal medicine, I think that would be the best route to go, coupled with a degree or work in public health.
There is a huge amount of preventible water borne diarrheal diseases that children and infants die from every day. They don't need physicians they need infrastructure and oral rehydration therapy.

Of course they need physicians!...AND infrastructure and ORT and vaccines...etc.
I agree, but if they have the infrastructure, proper sanitation, and proper water treatment the largest reasons for mortality will not be a factor. Plus, you don't really need a physician in those cases anyway. Your child has diarrhea they need oral rehydration therapy to replenish electrolytes and fluids and maybe an IV.
The improvement of health in our country has been just as much due to non-medical intervention than medical in the past century.
As said before, a physician can only do so much without equipment and something to work with.
