The villages were selected by researchers at Innovations for Poverty Action Bangladesh. The researchers paired 600 villages countrywide based on population size and density, geographic location, and any available COVID-19 case data. For each of the 300 pairs of villages, one was randomly assigned to receive the interventions while the other served as a control Disposable masks and received no interventions. Two-thirds of the intervention villages received surgical masks, while the other one-third received cloth masks.
