Time series of hospital patients for intervention scenarios in 2020. Horizontal dashed lines indicate hospital bed capacity in Dhaka District. Vertical lines indicate the start and end points of lockdown as implemented in Bangladesh. (A) Hospital patients in the absence of interventions, for the implemented lockdown plus extensions of up to 3 months, and for lockdown followed by household quarantine with community support teams. (B) Lockdown as implemented followed by compulsory mask wearing, considering nine mask effectiveness scenarios; ${\epsilon }^m$ describes the proportion reduction in outward emissions by mask wearers, while ${\rho }^m{\epsilon }^m$ describes the proportion protection to mask wearers from others’ emissions. (C) Combined impacts of the lockdown, household quarantine, and masks of different effectiveness.
