Ridgewood NJ, according to Johns Hopkins Center for Health Security on February 10, the US CDC published updated guidance regarding ways to improve the efficacy of facemasks, which supplements existing mask guidance. The recommendations focus on 2 principal factors in how masks provide protection: fit and filtering ability. The CDC continues to recommend wearing a “mask [that] fits snugly against your face” and selecting masks that have multiple layers to filter respiratory droplets. The new guidance includes several additional recommendations and tips for improving both aspects of mask use.
