Nurses collect the data of people about to get tested for COVID-19 at a testing center in the capital Kigali, Rwanda, Tuesday, July 28, 2020. Like many countries, Rwanda is finding it impossible to test each of its citizens for the coronavirus amid shortages of supplies but researchers there have created an innovative approach using an algorithm to refine the process of pooled testing that's drawing attention beyond the African continent.
