Communication is the key.... and the internet is generally pretty awesome for that. However, for rural medicine, the prerequisite (assuming infrastructure exists) is the ability to retrieve and parse the information. You need to be literate, have access to an internet enabled device, and know how to search for what you think ails you. Language could be a barrier too.

Use of social worker and nurse pairs to do rural visits and vaccinations are much more effective. Verbal communication in the local language can communicate any extra information they need. Question and answer sessions are more fruitful. There is much more information to be gleaned about the community as a whole with a visit. The social worker and nurse can always update data when they get back to a location with internet access and provide a lot more medical context than the residents.

I agree it is not an either or proposition. However I believe the more effective solution, under current conditions, is the human visit. While that happens, continue to build up the infrastructure around these areas; not just internet, but access to clean water, roads to take people to hospitals, access to electricity (local or from a grid), etc.

Steps have to be taken in all directions to grow the radius of community well being.
