Don’t tell me to “read it” - I posted it. You claimed masks other than N95 are useless. They are NOT. This talking point from certain people has become tired, to say the least.Read it. They provide relatively no protection compared to N95 masks. And that is if worn properly which a majority don't.
"Surgical masks are made of the same, or very similar, type of material as used in N95s, so the material in a surgical mask is quite capable of filtering out small particles, such as viruses in respiratory aerosols," Marr said. "Their weakness is that they are loose-fitting and do not seal to the face, so things can leak in and out of the gaps around the sides.
She said masks provide at least partial protection by reducing the amount of virus that is released by the wearer and reducing the amount breathed in from the surrounding air. "Partial protection is still useful because the more virus we inhale, the more likely we are to become infected, Marr said."
Research conducted throughout the pandemic confirms this. A September 2021 studypublished in Oxford Academic's Clinical Infectious Diseases journal found that surgical masks reduce viral shedding in aerosols from COVID-19 patients by 48% to 77%. Another study, published in the American Society for Microbiology Journals in October 2020, determined surgical masks reduce the amount of COVID-19 inhaled by the mask-wearer by about 50%.
Both the Centers for Disease Control and Prevention and the Food and Drug Administration acknowledge on their websites that surgical masks are generally meant to help protect against large droplets, splashes or sprays of possibly germy fluid. Both agencies also say that the masks should be used by the general public and health care personnel to help reduce spread.
"(The poster's) claim that surgical masks are primarily designed to protect the operative field from bacteria is correct," Dr. Michael Klompas, a hospital epidemiologist at Brigham and Woman's Hospital and professor of population medicine at Harvard Medical School, said in an email. "In terms of viruses and aerosols, (the poster is) only partly correct. (Surgical masks) provide partial protection against viral transmission. As such they lower the chances of transmission but they do not eliminate it."
