See Atypical Rt play out over the course of the COVID-19 epidemic in the United States, from Mar 2 through June 23. Areas with less transmission than expected are blue, those with higher than expected are yellow to red.
This week, Kinsa is launching a new metric of disease spread — Atypical Transmission (Rt) — which measures the rate at which influenza-like illnesses, including COVID-19, are spreading in different parts of the country in real-time; higher than average illness transmission is considered to be ‘atypical Rt’. Like our other measures, the aggregate, anonymized data visualized here is a product of Kinsa’s network of Smart Thermometers and accompanying mobile applications.
We’re still exploring whether this metric provides an even earlier indicator of spreading contagious illness than our Atypical Illness Signal. While we continue our analysis and scientific research on how much of a leading indicator this data is, we are able to use this new metric to monitor the impact of reopening policies across the country — for more details, please read our extended blog post on Atypical Rt.
While our team works on some final touches to add this to the HealthWeather map, here are a few highlights that show what Atypical Rt looked like at critical moments in the epidemic:
