Face Mask Study
The largest randomized control trial on the effectiveness of face masks to date revealed a positive relationship between the prevalence of mask-wearing and a decrease in COVID-19 transmission. The study, involving almost 350,000 people spread across 600 villages in rural Bangladesh, showed a 30% increase in facial coverings, following a series of interventions that encouraged residents to wear masks, resulted in roughly a 10% drop in COVID-19 transmission. The protective effect increased to nearly 35% for those over 65 years old, researchers said. A paper describing the study is awaiting peer review.
The rolling average of new US cases sits near 170,000 per day, with daily deaths averaging above 1,400. Explore the data here.
