Simulating an epidemic

Experiments with toy SIR models Help fund future projects: https://www.patreon.com/3blue1brown An equally valuable form of support is to simply share some of the videos. Special thanks to these supporters: http://3b1b.co/sir-thanks Home page: https://www.3blue1brown.com Awesome fan-made interactives: https://prajwalsouza.github.io/Experiments/Epidemic-Simulation.html https://learningsim.itch.io/pandemic-spread-simulation Simulations by Harry Stevens at the Washington Post: https://www.washingtonpost.com/graphics/2020/world/corona-simulator/ Simulations by Kevin Simler at Melting Asphalt: https://meltingasphalt.com/interactive/outbreak/ Excellent visualization of each country's current growth from Minutephysics and Aatish Bhatia: https://www.youtube.com/watch?v=54XLXg4fYsc Another good interactive to see what effect various parameters have on the shape of the curve: http://gabgoh.github.io/COVID/index.html If you want to hear a mathematician/epidemiologist's summary of COVID-19, I found this MSRI talk very worthwhile: https://youtu.be/MZ957qhzcjI Marcel Salathé on Contact Tracing: https://twitter.com/marcelsalathe/status/1242430736944201730 Thanks to these viewers for their contributions to translations Hebrew: Omer Tuchfeld ------------------ These animations are made using manim, a scrappy open-source python library: https://github.com/3b1b/manim Code for this video: https://github.com/3b1b/videos/blob/master/_2020/sir.py Honestly, given that the code for that video is meant for demo purposes, and not meant to reflect the true data of COVID-19, if you want to apply these ideas to the current situation I'd recommend looking for more professional epidemiological modeling tools that are less centered around animations and pedagogy and more focused on accurate predictions. For example, the Institute for Disease Modeling has a lot of models free for people to look at and play with. --------------- Opening music: Candlepower by Chris Zabriskie is li
