Nevada had the highest COVID-19 reproduction rate, while Massachusetts and Washington, D.C., had the lowest, according to rt.live.
Rt.live is a website that calculates the rate at which the virus is spreading. Measured by the average number of people who become sick from an infectious person, the site tracks the effective reproduction rate (Rt) of COVID-19 infections. If the value is less than one, the spread of the disease is slowing. The higher the Rt number, the worse the spread.
These rates were captured June 26, which is the most recent update made to the Rt.live site.
