Should You Go Out? (Terminated)

COVID-19 lockdowns are lifting. How safe is it to go out?

As countries around the world start easing COVID-19 lockdowns, Elena Polozova, a mathematician has developed a series of models to weigh up the risks of taking a walk, shopping and socializing. This website was built on top of Elena's models. The aim is to provide a simple to use interface for using the models as the models require intermediate to advanced level understanding of maths, physics and statistics. Thus, with little or no knowedge in the listed fields, anyone can use the models and make sense of the estimations.

How to use

Simply complete the fields with details (mostly estimates) of your outing. Then click on the 'ESTIMATE INFECTION RISK' button.

  • Thanks to Elena Polozova who built the estimation models in python on top of which this website is built. You can find the source code on Github. There's is also a Spreadsheet version of this model for more advanced users who want more control of the parameters. It's avalaible here, you could make a copy for yourself since the original is not editable
