Here’s a thread on the talk I gave at #ESCMIDGlobal 2026: “Toilets: Flushing and Spread of Pathogens” — nicknamed “You can’t outrun the plume.” Using published studies, I covered the key components shown below. There’s a surprising amount of data, but still a lack of high-quality intervention trials

If agriculture infection (transmission) control is anything like hospital infection control, we’re in trouble. Hospitals can test but we have almost no clinical trial data on optimal prevention strategies. Why? NIH (NIAID) isn’t allowed to fund hospital infection control studies. Why? No idea
