From: Time, space and social interactions: exit mechanisms for the Covid-19 epidemics

Comparison of the scenarios where the lockdown is relaxed only for a particular age class with respect to a full release policy. Strategies: YE = quarantine young and elderly, E = quarantine elderly. Notice that we have purposefully left the M class fully unrestrained in order to show how maintaining a partial, age-based lockdown could deeply change the effectiveness of the exit strategy, while maintaining active working force active.
