2 Face Masks Protect Better Than One

    En español | With the discovery of new, faster-spreading coronavirus
    strains in the U.S, it might be time to double down on face masks —
    literally — by wearing two at a time. Layering a cloth mask over a
    disposable medical procedure mask significantly boosts your protection
    against the coronavirus by ensuring a tighter fit against your face, a
    new study from the U.S. Centers for Disease Control and Prevention (CDC)
    shows.To get more news about mask supplier, you can visit official website.

    The CDC study also showed that you can substantially improve the
    performance of a surgical mask by knotting the ear loop strings where
    they meet the mask and tucking in mask edges. That eliminates gaps on
    the sides.

    Following the release of the study, the CDC published new guidance on
    how to improve your mask that emphasized the importance of fit. “Make
    sure your mask fits snugly against your face,” the CDC says. “Gaps can
    let air with respiratory droplets leak in and out around the edges of
    the mask.”

    Although COVID-19 vaccination has started, masking is still important
    because the virus will continue to spread and sicken people until most
    of the population is immunized. And with the discovery of new variants
    that could be up to 70 percent more transmissible, some experts say it's
    even more prudent to wear not just any face covering, but a
    high-quality one (or two).

    "Last year, we wanted to get as many people to wear masks as
    possible,” Marr said. “This year, with new, more transmissible variants,
    we really need to think about improving our masks.”Many Americans have
    been wearing the same cloth masks for months — in many cases, homemade
    versions originally created to ease a limited supply. These days,
    however, there are hundreds of options for sale, including nonmedical
    disposable surgical masks, and cloth versions with multiple layers and
    special filters.

    When I think of who I want to wear a mask with increased fit and
    filtration, I think of older adults and vulnerable people with
    underlying conditions,” said Monica Gandhi, M.D., an infectious disease
    doctor and professor of medicine at the University of California, San

    Gandhi and Marr co-authored a commentary in Cell Press on Jan. 15
    with recommendations about how to improve the protection you get from
    your mask.

    Other countries have already taken steps to get people to wear
    higher-quality masks: Hong Kong distributed six-layer masks to all of
    its citizens; Austria sent high-grade medical masks (the equivalent of
    N95s) to residents over age 65; and Germany recently began mandating
    medical-grade masks in shops and on public transit.

    A CDC division that oversees medical devices is working to develop
    filtration standards that will allow masks to include a label showing
    how well they block infectious particles. That work is expected to be
    completed by April, a spokeswoman said.

    In addition, some U.S. scientists are calling on the federal
    government to increase production of medical-grade masks and make them
    more widely available.
