"As of May 2019, more than 65% of blood deliveries in Rwanda outside of the capital city Kigali use Zipline drones." https://en.wikipedia.org/wiki/Zipline_(drone_delivery)#Rwand... Tanzania is not listed in the wikipedia article but very nice to see the project is still ongoing.

very interesting. The issue is that many countries are banning civil people from using drones. However, I agree that it should be organized to be used properly as you said for medical purpose it would be great.
