Patients with a type of blood cancer called multiple myeloma had a widely variable response to COVID-19 vaccines—in some cases, no detectable response—pointing to the need for antibody testing and precautions for these patients after vaccination, according to a study published in Cancer Cell in June.
The WHO and the CDC recommend keeping a certain distance between people to prevent the spread of COVID-19. These social distancing recommendations are estimated from a variety of studies, but further research about the precise mechanism of virus transport is still needed. In Physics of Fluids, researchers demonstrate normal breathing indoors without a mask can transport saliva droplets capable of carrying virus particles to a distance of 2.2 meters in a matter of 90 seconds.
A new Houston Methodist study shows a rapid return of seasonal respiratory viruses after COVID-19 restrictions were relaxed in Texas, demonstrating the apparent effectiveness of masking, distancing and other precautionary measures at stopping the spread of respiratory illnesses. This rise in infections to pre-pandemic levels followed updated governmental guidelines lifting mask, distancing and occupancy requirements.

The proliferation of face coverings to keep COVID-19 in check isn’t keeping kids from understanding facial expressions, according to a new study by University of Wisconsin–Madison psychologists.
Simply wearing a mask may not be enough to prevent the spread of COVID-19 without social distancing. In Physics of Fluids, researchers tested how different types of mask materials impacted the spread of droplets that carry the coronavirus when we cough or sneeze. Every material tested dramatically reduced the number of droplets that were spread. But at distances of less than 6 feet, enough droplets to potentially cause illness still made it through several of the materials.
Some people still refuse to wear a mask. So UNC School of Medicine scientists researched the protectiveness of various kinds of consumer-grade and modified masks, assuming the mask wearer was exposed to the virus, like when we interact with an unmasked infected person.
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.
A team of American and Canadian researchers report that while they may feel uncomfortable, there is little empirical evidence that wearing a facemask significantly diminishes lung function, even when worn during heavy exercise.
A medically challenging case presented at this year’s virtual ACAAI Annual Scientific Meeting revealed that for a man with several skin allergies, mask-wearing triggered his contact dermatitis.
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.
In a wide-ranging talk with UCLA Health physicians, Wednesday, Oct. 28, United States Surgeon General Jerome Adams, MD, MPH, addressed the politicization of the pandemic and the means of containing the spread of COVID-19. He also offered hope that a vaccine for the virus will be available by year’s end.

New Brunswick, N.J. (Sept. 16, 2020) – FDA guidelines for making 3D-printed masks, face shields and other personal protective equipment (PPE) in the COVID-19 era fail to defend against cyberattacks, according to Rutgers and Georgia Tech engineers. Due to the…
A novel study showed that people who wear face coverings tend to have more contacts with others, putting them at risk of contracting COVID-19. Masking directives should accompanied by forceful messaging stressing the importance of social distancing.
N95 masks achieve 95% efficiency at filtering out tiny 0.3-micron particles, while maintaining reasonable breathability, thanks to a layer of polypropylene fibers incorporating electrical charges to attract particles. Extended usage and decontamination, provoked by severe shortages during the pandemic, can easily remove the charges and degrade filtration efficiency. In Physics of Fluids, researchers share a method to restore the filtration efficiency of N95 masks to out-of-box levels, as long as the mask is not structurally compromised.
