"samples retrieved from patients have to be shipped back to the capital." This seems wildly inefficient. Stealing the idea from a fps game but you should just get the samples to the nearest helium tank,inflate balloons, and have some other government have planes to snatch the balloon. As convoluted as this seems, given the possible delay of intelligence due to having to drive the sample all the way from remote villages to a capital, the fastest way would to get the package somewhere is air, and the faster it get on a plane the better. Just like the storms damaging US infrastructure showed us how important access to rural areas.
