One of the most enlightening pieces I have seen is the news coming out of Vo in Italy.
It's a small town of 3300 people and the local university tested every citizen as part of a study.
This highlighted who had it and more importantly, who was asymptomatic (showing no signs of infection despite being infected and capable of passing the virus on).
Over a period of time, isolation measures and retesting they showed that the infection rate went to zero.
Obviously a small scale exercise, but as an educational device for how important self-isolation and social distancing are in the absence of 100% testing it needs to be broadcast to a much larger audience.
Vo go to zero
