I had the pleasure of being in the audience as Vodafone Group CEO Vittorio Colao spoke at the mHealth Summit in London last week, and was astonished to find him mentioning our very own EpiSurveyor as an example of the power of mobile technology for public health. He noted, correctly, that EpiSurveyor enables workers to make quicker, better and much more informed responses, and leads to much more informed policy making.

Of course, EpiSurveyor would not have been possible without the support we've received over the years from both the Vodafone Foundation, charitable arm of Vodafone Group, and also the United Nations Foundation. Still, I must admit that I didn't realize that word had trickled all the way to the top of Vodafone.
