Global health can be improved with inexpensive diagnostic tools, patient reminders and efficient immunization schedules through mobile technology, declared Bill Gates, founder of Microsoft.
"The mobile phone is pretty interesting for lots of things," Gates said in a keynote address at the mHealth Summit here, a gathering of public and private sector groups and companies involved in mobile technology and health.
"There's a whole lot of opportunities," said Gates, who stepped down from day-to-day duties at Microsoft two years ago to concentrate on global health care through the Bill and Melinda Gates Foundation.
"I think we have to approach these things with some humility though," Gates cautioned, pointing out that "there's no Internet and data connections" in much of the world.
"I do think there's absolutely a role (for mobile technology to impact global health) but I think we have to hold ourselves to some pretty tough metrics to see if it's really making a difference or not."
Gates said the cellphone can allow health care professionals to "actually be there with a patient, to be there in a clinic which might not be staffed with wholly trained doctors."
"TB diagnosis. That would be a huge thing," Gates said.
"When I think about the biggest impacts I think of patient reminders," he added. "You could get people to take medicines regularly, that's a huge one."
Gates said mobile technology could also help improve immunization programs.
