Can you create a new device that quickly diagnoses HIV, TB, malaria, and other diseases… accepts different samples, like blood, saliva, and sputum… is affordable… and reliable… and will work in a small clinic that has only a few hours of electricity a day?

Today, five public-private partnerships have taken up the challenge. The journey from idea to reality is a long one. For one thing, the partners had to figure out whether making such a machine was even technically feasible. It is—several of them have working prototypes.

This is one of them, the Stratos, which our foundation is developing with a Seattle-based medical engineering company:

Lessons from William Foege

“We learned the need for

OPTIMISM. The trouble with

being an optimist, of course, is

that people think you don’t

know what’s going on. But it is

the way to live. I tell students

there is a place for cynicism and

a place for pessimism and

whenever you need it, contract

for it but don’t get those people

on your payroll. They will ruin

your day. We were an optimistic

group.”
