We hope this email finds you doing well at the end of the week.
Early on in this pandemic, we wrote to you with a few new terms that we suggested would become part of our everyday vocabulary: Social Distancing and Flattening the Curve. It's hard to believe that this was less than two months ago, as it feels like a lifetime...
We come to you today with another term that you are about to become very familiar with, and that is R-Naught. You will likely begin seeing and hearing about this quite often going forward, as it is a significant metric that the states are all looking at. Known as the "basic reproductive number", it measures how many people are infected by a disease by a single person. You'll see it shown as R0, or also as Rt, which is a nuanced difference of the R-Naught equation which is the virus' actual rate of transmission of a given period of time (which is t).
Perfectly simple, right??? Got it? Good...
I've included three references that should really help with this. The first is a 9 minute talk from the Khan Academy that does a great job of explaining the term. The second is an article that has been out there for a month, and was written by an author in Hong Kong as the virus was at its height overseas. Finally, is a great page that a local doctor mentioned to me three weeks back and I've been referring to daily. It is a quick, visual way to understand where the Rt numbers are trending.

Easing Coronavirus Lockdowns
We hope that these resources help you in understanding this term that we'll be watching closely, in the hope that we keep seeing the number decrease over time.
Have a great Mother's Day weekend, and please let us know if there is anything that we can be doing for you.
