UCLA Fielding School of Public Health Researchers Say Mask Mandates Could add $1 Trillion to the U.S. GDP

The team, including UCLA Fielding School of Public Health professors Anne Rimoin and Christina Ramirez, found that near-universal adoption of nonmedical masks in public, combined with complementary public health measures, could successfully eliminate spread of the infection. and add $1 Trillion to the U.S. GDP.

Face Masks Provide Additional Communication Barrier for Nonnative Speech

Though face masks are important and necessary for controlling the spread of the new coronavirus, they result in muffled speech and a loss of visual cues during communication. Sandie Keerstock, Rajka Smiljanic, and their colleagues examine how this loss of visual information impacts speech intelligibility and memory for native and nonnative speech. They will discuss these communication challenges and how to address them at the 179th ASA Meeting, Dec. 7-10

FSU researchers investigate how face shape affects COVID-19 mask performance

Face masks are helpful in preventing the spread of COVID-19, but researchers believe they can be made even more effective, something that has implications far beyond the current pandemic as masks could become a more commonly used public health intervention. Kourosh Shoele, an assistant professor in the Department of Mechanical Engineering at the FAMU-FSU College of Engineering, is part of a team that has received an $800,000 grant from the National Science Foundation to improve the efficacy of face masks as a defense against COVID-19 and other pathogens.

Masked Education: Which Face Coverings are Best for Student Comprehension?

With the ubiquity of masks due to the coronavirus pandemic, understanding speech has become difficult. This especially applies in classroom settings, where the presence of a mask and the acoustics of the room have an impact on students’ comprehension. Pasquale Bottalico has been studying the effects of masks on communication. He will discuss his findings on the best way to overcome hurdles in classroom auditory perception caused by facial coverings at the 179th ASA Meeting.

Valves on N95 Masks Do Not Filter Exhaled Droplets

Matthew Staymates, fluid dynamicist at the National Institute of Standards and Technology, is studying different mask types to determine which are the most effective at reducing disease transmission. In Physics of Fluids, he describes exploring the basic flow dynamics of N95 masks with or without exhalation valves. To do this, he generates stunning video from his schlieren imaging, a method to visualize the fluid flow away from the surface of an object, and light scattering.

What’s That Growing on Your Face Mask?

Many people reuse masks and other face coverings many times without sanitizing them. That is likely because current sanitization methods can be cumbersome. A new device using a hanging rack and UV-C light can sterilize up to six masks and other items simultaneously and quickly, killing bacteria, yeasts, mold spores, and viruses. This device has shown its efficacy against pathogens including the highly-contagious E-coli, which was eradicated in about one minute.

UCLA Health infectious disease experts tout critical role mask wearing plays in limiting spread of COVID-19

With thousands of new cases logged daily and a vaccine to fight COVID-19 still in development, UCLA Health infectious disease experts are encouraging people to continue to wear masks as the best method of protecting against virus transmission.

Estimating Risk of Airborne COVID-19 with Mask Usage, Social Distancing

In Physics of Fluids, researchers used a model to understand airborne transmission that is designed to be accessible to a wide range of people, including nonscientists. Employing concepts of fluid dynamics and factors in airborne transmission, they propose the Contagion Airborne Transmission inequality model. While not all factors may be known, it can still be used to assess relative risks. The researchers determined protection from transmission increases with physical distancing in an approximately linear proportion.

COVID-19 Cough Clouds in Closed Spaces

As the pandemic continues, researchers have increasingly focused on the extent to which respiratory droplets carrying the coronavirus travel and contaminate the air after an infected person coughs. While scientists have studied the properties of air at the mouth, less is known about how these properties change as the cough cloud travels. In Physics of Fluids, researchers estimate the evolving volume of the cough cloud and quantify the reduction in its volume in the presence of a face mask.

Face Masks Unlikely to Cause Over-exposure to Carbon Dioxide, Even in Patients with Lung Disease

New research findings contradict statements linking wearing face masks to carbon dioxide poisoning by trapping CO2. During the COVID-19 pandemic the wearing of face masks has become a highly political issue with some individuals falsely claiming that wearing face masks may be putting people’s health at risk. The study published in the Annals of the American Thoracic Society shows otherwise.
