Researchers at Stanford created an interactive model to simulate the results of different long term COVID-19 intervention strategies. The models show that lifting strong social distancing measures too quickly (between 5 and 10 months) will result in a resurgence of cases that could overwhelm hospital capacity. One solution to this in the long term is the lightswitch method, where strong social distancing measures are turned on once a hospital capacity threshold is reached (e.g. 15 patients), and turned off once the hospital numbers drop below a lower threshold (e.g. 2 patients). This method balances fighting the spread of COVID-19 and our lives and economies returning to a somewhat normal operation.
