"There's a whole lot of opportunities. I think we have to approach these things with some humility though," added Gates, noting that much of the developing world still has no internet or data connections.

Gates noted how phones can impact on TB diagnosis, as well as offering better immunization programmes and patient reminders. "You could get people to take medicines regularly, that's a huge one."
