    Your colorful, trendy cloth mask may not match Omicron as experts say to junk ‘fashion accessories’

    It may be time to remove your colored cloth masks, which match a T with each garment, as experts point to the lack of safety standards for reusable masks in the face of the Omicron threat.

    “These can be really good or really terrible, depending on what fabric is used,” said Trish Greenhallug, a professor at Oxford University’s Primary Health Care Service, quoting Bloomberg. Double or triple-layer mask made of a mixture of materials. May be more effective, but most fabric covers are just “fashion accessories”.

    With the rise of the Omicron case worldwide, the mask mandate has returned. Earlier this month, Britain relaxed the rules in the summer, reintroducing mandatory masks on public transport, shops and some indoor venues. Several others followed suit.

    According to Greenhall, the main problem with cloth masks is that they do not have to meet any health standards. In contrast, those who make N95 respirator masks, for example, need to make sure they filter out 95% of the particles, Bloomberg says.

    “The problem here is that if you have a single-layer, the filtration capacity is minimal and there’s no difference,” Peter Juni, head of the Ontario Science Advisory Table, told CTV News in an interview last week.

    Dr. Liana Wayne, a medical analyst at CNN, says that cloth masks are useless in the fight against the spread of the Omicron form of Kovid-19, instead encouraging viewers to wear three-layer medical masks.

    “I would say if you want to go [for events]Make sure you’ve been vaccinated and boosted, make sure you’re wearing a mask, even if it’s outside, if there’s a lot of people around you, wear a three-ply surgical mask, “says Dr. Wayne. Don’t wear a mask. “

    “Cloth masks are a bit more than facial decorations. There is no place for them in the light of Omicron. And so wear a high-quality mask, at least a three-ply surgical mask, “he added.

    Ashley Stykjinsky, a contagious disease fellow at Stanford University, told Bloomberg in October that “there is very little real-world research examining the effects of covering the face with a cloth.”

    “Different laboratories have measured the filtration efficiency of different fabric materials used in masks. Fabric materials typically block 10-30 percent aerosol-sized particles that contribute to this [the] The airborne spread of SARS-CoV-2, ”he added.

    Lab studies have shown that surgical masks, such as the N95, block about 95 percent of aerosol-shaped particles.
