In 1918, influenza killed tens of millions, more than World War I. For over a century, the true origin of the “Spanish Flu” stayed uncertain, amplified by wartime censorship and patchy records. Now, newly recovered 1918 genomes from preserved lung tissue provide the strongest evidence to date. Researchers sequenced century-old samples from multiple continents, revealing a virus already highly adapted to humans and pointing to a likely Western Hemisphere origin before it spread globally via troop movements. This isn’t just history, it’s a blueprint for spotting future threats from avian influenza spillovers and a reminder of the hidden value in medical archives. You’ll learn: - How scientists recovered and sequenced 1918 H1N1 genomes from preserved lung tissue - Why the origin stayed hidden (censorship, data gaps, sampling bias) - What the new genomic evidence says about where it likely began - How those lessons help detect pandemics today Chapters (08:19) 00:00 Why the 1918 origin
