Before revision:  Many proposed exit strategies have risks and uncertainties which could lead to a second wave of infection 1 , 2 . We demonstrate that our proposed policies have the potential to be a method of virus suppression, while at the same time allowing continued(albeit reduced) economic activity.
After revision:  Many proposed exit strategies have risks and uncertainties which could lead to a second wave of infection repeating waves of infection. We show -- as proof of concept grounded on rigorous mathematical evidence -- that periodic, high-frequency alternation of into, and out-of, lockdown effectively mitigates second-wave effects, while allowing continued, albeit reduced , 2 . We demonstrate that our proposed policies have the potential to be a method of virus suppression, while at the same time allowing continued(albeit reduced) economic activity.
