Research Results: Double Masking During the COVID-19 Pandemic

Environmental Protection Agency - Center for Environmental Solutions and Emergency Response (CESER)

Research Alert

EPA, along with their co-authors at UNC, recently published an article titled “Fitted Filtration Efficiency of Double Masking During the COVID-19 Pandemic” in JAMA Internal Medicine. With global vaccination efforts against SARS-CoV-2 rapidly increasing, public health officials have continued to encourage the use of face masks to mitigate virus transmission. The article addresses the limitations of a previous study done by US Centers for Disease Control and Prevention (CDC), which reported that wearing two masks increased the effectiveness of preventing spread of COVID-19. This study considers the limitations of the CDC’s research on type and combinations of different masks as well as the CDC’s use of head forms rather than humans. This study compared the fitted filtration efficiency (FFE) of the most widely available masks worn singly, doubled, or in combinations.

Results demonstrated that the most significant improvement to FFE occurred from the combination of a medical procedure mask worn underneath a cloth mask, out of all combinations considered.

Weizmann Institute of Science

Scientists at the Weizmann Institute and the Israel Institute for Biological, Chemical and Environmental Sciences took a novel tack to investigating SARS-CoV-2’s powerful ability to infect, finding that the virus deploys an apparently unique three-pronged strategy to take over the cell’s protein-synthesis abilities. The work could help develop effective Covid-19 treatments.

Rapid COVID-19 Diagnostic Test Delivers Results Within 4 Minutes With 90 Percent Accuracy
Perelman School of Medicine at the University of Pennsylvania

A low-cost, rapid diagnostic test for COVID-19 developed by Penn Medicine provides COVID-19 results within four minutes with 90 percent accuracy. A paper published this week in Matter details the fast and inexpensive diagnostic test, called RAPID 1.0. Compared to existing methods for COVID-19 detection, RAPID is inexpensive and highly scalable, allowing the production of millions of units per week.
