While it's a minor logistical challenge, it's simple enough to ship this in a liquid nitrogen dewar.
Even very small cities will have liquid nitrogen facilities. Shipping from the nearest city to most of the population sounds very doable in 24 hours.
Remember you only need to get most of the population to halt the spread. If there's some tiny village 3 days hike away in the rainforest, you can skip them.
