Firearm purchasing and storage during the COVID-19 pandemic.

To better understand motivations behind purchase and storage of firearms during the COVID-19 pandemic, we used Amazon Mechanical Turk to conduct an online survey of individuals who did and did not purchase a firearm since 1 January 2020 in response to COVID-19. The survey was fielded between 1 and 5 May 2020. We asked about motivations for purchase, changes in storage practices and concern for themselves or others due to COVID-19. There were 1105 survey respondents. Most people who purchased a firearm did so to protect themselves from people. Among respondents who had purchased a firearm in response to COVID-19 without prior household firearm ownership, 39.7% reported at least one firearm was stored unlocked. Public health efforts to improve firearm-related safety during COVID-19 should consider increasing access to training and framing messages around the concerns motivating new firearm purchase.

Novel manufacturing of simple masks in response to international shortages: Bacterial and particulate filtration efficiency testing.

Many healthcare systems have been forced to outsource simple mask production due to international shortages caused by the COVID-19 pandemic. Providence created simple masks using surgical wrap and submitted samples to an environmental lab for bacterial filtration efficiency testing. Bacterial filtration efficiency rates ranged from 83.0% to 98.1% depending on specific material and ply, and particular filtration efficiency rates ranged from 92.3% to 97.7%. Based on mask configuration, specific surgical wrap selected, and ply, the recommended filtration efficiency for isolation and surgical masks of 95% and 98%, respectively can be achieved. These alternative masks can allow for similar coverage and safety when hospital-grade isolation masks are in short supply.
