Case in point: Polio is endemic in only three countries today: Afghanistan, Pakistan and Nigeria. While in Afghanistan it'd be possible for it to be down to the war, in Pakistan and Nigeria it is down to skepticism and misinformation from religious groups (often based in past experiences) that are often amongst the most important information bearers in their communities. When people don't have other sources than a government they don't trust and other biased groups giving them false information, it's no wonder many misinformation proliferate.
The difference with Afghanistan, Nigeria and Pakistan is that it is endemic at least in parts of the countries, meaning it is regularly found in the population and that it is self-sustained. Elsewhere the outbreaks are sporadic and isolated enough that they die back.
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.
The population density in some developing countries is extremely low. Botswana for example has roughly 2mio inhabitants of which roughly a quarter live in Gabs and yet another maybe 10% in the next 5 bigger towns. That leaves the rest of the country with an average population density of less than 2person/square km. Bringing people to a hospital by car on a good road can easily take a day or more. It's also not viable to have an educated doctor able to make that choice in each of the remote villages. So you really really need to find a good way to offload that decision to a person that's remote.
n.b. Botswana is a fairly well developed country, I just choose it as an example since I have family ties there and know the situation better than say Namibia which is similar in the population distribution.
If you're imagining a situation in which one individual in an outlying community gets sick with mysterious symptoms that turn out to be malaria, you have simply failed to grasp the magnitude of the problem.
We already have communications options available in those regions. The very same ones used over the last decades, whether its radio, hardline phones, cellular or even satellite.
Doctors and nurses out there already have communications. The issue here is that spending money to provide internet to the masses there is not as beneficial as making sure they live to use it.
So the best available communication is often cellular, if any.
On the other hand malaria is a disease that only affects some parts of the population - namely the one that lives in malaria affected regions. Large parts of southern Africa are mosquito-free, hence no Malaria. To make up for that there's a ton of others diseases, so if you eliminate Malaria, you still have to fight Schistosomiasis [1], Trypanosomiasis (sleeping sickness) [2] HIV and a lot of other diseases for which treatments may or may not exist. In a country where the average infection rate with HIV hovers at about 30% the gain from eradicating Malaria is limited at best. Let's not get into poverty and access to most basic health care.
It's not a simple problem that allows for a simple solution and even eliminating every conceivable disease that affects people in developing countries will only be one minor factor to improving the situation there. Those people need access to knowledge and information as much as they need health care and water. Otherwise they'll forever be stuck on western subsidies - just healthier and longer.

Doctors and nurses may have communications, but many countries do not have doctors and nurses even in every city, much less every little village.
It's clear we should be careful about not displacing funding for basic health care improvement with basic internet access, but they are not nearly always in opposition, and besides providing health care information, uses such as improving economic opportunities by giving access to market/pricing information also matters - for someone having to spend days getting their stuff to market, going to the right town to get the best price will also affect health: ability to afford sufficient food and shelter for starters.
Telecoms is available world wide for a price, via satellite. Internet is also available worldwide for a price. Broadband is coming in the next few years, worldwide, for a bigger price. Health revolution worldwide is not even on the horizon.
Endemic poverty is a complicated social and political phenomena which is maintained due to a variety of causes. Even if tomorrow you eliminated malaria, it's very doubtful the conditions in any country where it's a problem would improve. A case in point is famine - we have more then enough food today to feed a population of 10 billion or more people on the planet fully. But people still starve to death every day. And even when we give food aid for free, we still keep having the same issue - even when we're actively giving it.
When you start trying to order your problems by perceived importance, we get nothing done. Sure you think, I'd hate to die of malaria. But you live in a first world country - if you don't die of malaria, you don't then imagine that you'll still have nothing to eat tomorrow, or that you lack all of the education you take forgranted. Or that there'll be no jobs, or that even if you work hard you'll still be paying bribes just to get a driver's license. Or come the local elections if you don't guess the right side to be seen supporting you'll be murdered or raped, or both.
I'd say he's at least partially wrong. Diseases are often cause by lack of knowledge and education, outburst can often be contained with good means of communication. I know people doing projects that use the internet (or cellphone text messages) to allow remote villages to better manage the available health resources. Internet connectivity allows the local healing person, often a nurse or similar level to send pictures and descriptions of wounds and health issues to a qualified doctor. This allows the doctors to actually go to the villages where they're needed most - actually saving lives. So the internet may very well be a live-saving thing.
The other point that people forget is that it's extremely hard to completely eradicate a disease. The only disease that I know of that's completely eradicated is the small pox. Polio, leprosy and even the black death are merely contained to a varying degree, often only in developed countries even though vaccines or cheap, effective treatments exist. So investing in connectivity and helping to spread information may actually be a viable path.
