Researchers develop virus-fighting face masks, killing germs on contact

Traditional face masks, including N95s and KN95s, offer protection against illness and infection but must be disposed of once they come in contact with viruses, thus generating significant plastic waste. Researchers have developed a simple method that would give N95 face masks antiviral and antibacterial properties, which could allow them...

Scientists Warn Against Repeated Re-Use of Masks for at-Risk Group

Researchers have suggested that people with compromised immune systems should avoid re-using face masks due to germ growth. The finding was made as part of a Japanese study into face mask hygiene. In the study, the researchers surveyed 109 people on their face mask usage and collected bacteria and fungi samples from both the inner and outer sides of their masks.

Bacterial and fungal isolation from face masks under the COVID-19 pandemic

The COVID-19 pandemic has led people to wear face masks daily in public. Although the effectiveness of face masks against viral transmission has been extensively studied, there have been few reports on potential hygiene issues due to bacteria and fungi attached to the face masks. We aimed to (1) quantify and identify the bacteria and fungi attaching to the masks, and (2) investigate whether the mask-attached microbes could be associated with the types and usage of the masks and individual lifestyles. We surveyed 109 volunteers on their mask usage and lifestyles, and cultured bacteria and fungi from either the face-side or outer-side of their masks. The bacterial colony numbers were greater on the face-side than the outer-side; the fungal colony numbers were fewer on the face-side than the outer-side. A longer mask usage significantly increased the fungal colony numbers but not the bacterial colony numbers. Although most identified microbes were non-pathogenic in humans; Staphylococcus epidermidis, Staphylococcus aureus, and Cladosporium, we found several pathogenic microbes; Bacillus cereus, Staphylococcus saprophyticus, Aspergillus, and Microsporum. We also found no associations of mask-attached microbes with the transportation methods or gargling. We propose that immunocompromised people should avoid repeated use of masks to prevent microbial infection.

Click here to read the full article. Though mask restrictions are easing across the country (and around the world), officials say you shouldn’t be taking off your masks just yet, especially if you’re in crowded places or starting to travel.

Kanye West confuses fans with face mask at BET Awards 2022

The masked man strikes again. Kanye West made a surprise appearance at Sunday’s 2022 BET Awards, presenting Sean “Diddy” Combs with a Lifetime Achievement Award while wearing one of his signature face-obscuring masks. Unlike some of the coverings he’s worn in the past, however, this one — which Ye topped with a pair of black sunglasses for an even more incognito look — lacked any sort of ventilation, and viewers at home sensed the rap superstar was struggling to get through his speech in the style. “Kanye West bout to pass out in that hot ass mask and outfit on stage.
