Track the Spread of COVID-19 in North Carolina

Early in the coronavirus pandemic, Cone Health began tracking data from multiple sources in order to better understand the spread of infection in our state. Many organizations and members of our community have requested information. While we cannot provide answers to all questions, we want to be right here with you providing data and analysis to help you make decisions.

We have developed this website for our community. It contains data from numerous publicly available sources. Our hope is that you can use this analysis to put COVID-19 into context.

Cases and Reproduction Numbers by County

The Reproduction Number is the average number of secondary cases caused by a single case. If the reproduction number is greater than 1, that means that each infected individual, on average passes the infection on to more than 1 person. If the reproduction number is less than one, that means that epidemic is dying out as each infection leads to fewer and fewer infections.1

The spread of the infection is increasing if the reproduction number is greater than 1, while the spread of the infection is decreasing is the reproduction number is less than 1. An infection is said to be endemic or stable if the reproduction number is equal to 1 (meaning that each infection on average is passed to one individual). The infection trend compares the estimated reproduction number today to the reproduction number a week ago to estimate if the reproduction number is increasing, decreasing, or relatively stable for each county.
