Florence Area Reproduction Number (Rt)



What Does This Graph Show?  

The graph shows the R-Naught values over time. R-Naught (also referred to as Ro, or the Reproductive Number) indicates the average number of people who are infected by each person who gets infected. If R-Naught is greater than 1 the epidemic will continue to be sustained. If R-Naught drops below 1 eventually the epidemic will cease to exist.

The basic reproduction number is when there is no immunity from past exposures or vaccination, nor any deliberate intervention in disease transmission. We refer to R as an 'effective reproduction number' when there is some immunity or some intervention measures are in place.
