re: Alabama Board Coronavirus Thread

A measure of how quickly a disease spreads. As I understand it a 1 means that for every infection, 1 future infection can be expected and the rate of infection will remain static. Less than a 1 means for every current infection there will be less than 1 future infection, meaning spread of the disease is subsiding. Anything over 1 means for every current infection there will be more than 1 future infection, meaning the spread is growing.
