Instagram founders Kevin Systrom and Mike Krieger have teamed up to launch a website to track the spread of Covid19.
This is their first product together that is since the duo leaving the Facebook . The website, RT.live, uses a statistics known in epidemiology as the effective reproduction number. It tracks the average number of people who catch the virus from one infected person. Rt.live is an up-to-date tracker of how fast COVID-19 is spreading in each state.
“Rt” measures the average number of people who become infected by an infectious person. The higher above the number 1, the faster COVID-19 races through a population, while a number below one shows the virus receding. For example, Rt.live displays that Georgia has the highest, most dangerous Rt score of 1.5 while New York is down to 0.54 thanks to aggressive shelter-in-place orders.
