Ebola may have been spreading for months in the DRC before anyone recognized it. A new reconstruction suggests the outbreak was already widespread in the gold-mining town of Mongbwalu by January. It wasn’t officially declared until 15 May. Why did no-one raise the alarm? My story for @science.org 🧪
