"Rwanda did a few things that are quite smart," says Sema Sgaier, the head of the Surgo Foundation, which has just launched a new data tool to analyze trends around COVID-19 across Africa. "One is they responded really early. They put some of the most stringent lockdowns in place compared to every other African country. In fact, we've been monitoring physical distancing data across the continent and Rwanda fares, I think, second; they've physical distanced the second most across Africa" — a conclusion based on mobile phone movement data. South Africa is No. 1.
