A good site to look at is IAMAT - International Association for Medical Assistance to Travellers. Excellent information, and membership confers a booklet with vetted out physicians in any parts of th eworld. Membership is free, though they always welcome contirbutions as a non-profit. I've used IAMAT to find physicians in Kenya, Malawi, New Zealand, Australia and other places over the years.

They offer downloadable brochures for free:

The following IAMAT publications are available for free in pdf format.
