“In Congo Republic, many suspected monkeypox cases trace back to the village of Manfouete, a six-hour boat trip from the nearest airport. The village has 1,600 people, no electricity and no running water. The scientists are traveling upriver in a big motorized boat that looks like an open-air school bus. They must bring everything they need for their work. So a second boat — a long, wooden dugout canoe — will follow later carrying most of their supplies: boxes of traps and test tubes, a portable centrifuge, jerrycans of gasoline, a 25-kilogram sack of rice and lots of bottled water.” WaPo reporters were allowed to tag along as US and Congolese scientists tracked a virus, and came back with an amazing report on a science-driven war fought on a front most of us never consider: Chasing A Killer.
