The choice stating that 450,000 people were spared from infection in states that mandated masks during the COVID-19 pandemic is supported by various studies that analyzed the effectiveness of mask mandates. Research indicates that such mandates significantly reduced the transmission of the virus by increasing compliance with preventive measures in the community.

Masks are a simple yet effective tool that helps to minimize the spread of respiratory droplets, the primary transmission method for COVID-19. Evidence from public health studies showed that areas with mask mandates experienced lower infection rates compared to regions without such measures. The estimate of 450,000 people reflects the collective impact of mask-wearing on public health during a critical time when hospitals were under significant strain, and health systems were trying to manage an unprecedented number of COVID-19 cases.

The figure highlights the importance of public health interventions and signifies how policy decisions can impact community health outcomes. Quantifying the number of infections avoided demonstrates the effectiveness of such mandates in controlling the spread of infectious diseases.
