There’s a ton of phenomenal efforts to record and post COVID-19 data publicly. The next step is querying and joining across it. In that spirit, my co-founder, Jonathan Mortensen, and I spent the weekend building a way to quickly query and join the COVID-19 data sets with SQL.<p>Using our tool you can, for example, join the John Hopkin's data set (tracking infections and fatalities) with CovidTracking (testing data). We’re adding in census data and other useful epidemiology reference data, too. That's not been available before! We’re almost to the point where the data sets will update automatically, so you can be sure the data is always fresh. Please check our tool out and give us feedback: https://bit.io/covid<p>Note that this tool is intended for folks who already know SQL and can connect to us via tools that speak SQL.
