Summaries of health outcomes and working days lost for a range of interventions during 2020. NI=no intervention, L=lockdown, Q=household quarantine with community support teams, M=compulsory mask wearing. The black bars for the lockdown (L) intervention describe the range of each outcome over the scenarios where lockdown is as implemented in Bangladesh and where this lockdown is extended by up to three months. For interventions involving mask-wearing (M), the three coloured bars describe scenarios with different values of ${\epsilon }^m$, the proportional reduction in outward emissions by mask wearers. These bars range over the scenarios where masks provide no protection to the wearer to where they provide proportional protection to the wearer from others’ emissions that is equal to ${\epsilon }^m$.
