With flu season upon us, many people are wondering what precautions they can take to prevent transmission of the H1N1 (swine flu) virus. Facemasks, which refer to disposable masks like the ones health workers occasionally wear, are designed to block large particle droplets, splashes, and sprays from reaching the wearer's mouth and nose. Frontiers Effectiveness of Surgical Face Masks in Sep 25, 2020 · Background:Acute respiratory illnesses (ARIs) are the most common respiratory infectious diseases among humans globally. Surgical mask (SM) wearing has been shown to be effective in reducing ARI among healthcare workers. However, the effectiveness of SM in reducing ARI in the non-healthcare settings remains unclear. This review aims to summarize and assess the Masks Are Neither Effective Nor Safe:A Summary Of The This 1920 analysis of cloth mask use during the 1918 pandemic examines the failure of masks to impede or stop flu transmission at that time, and concluded that the number of layers of fabric required to prevent pathogen penetration would have required a suffocating number of layers, and could not be used for that reason, as well as the problem

The preferred placement for patients who require Airborne Precautions is in an airborne infection isolation room (AIIR).
measure levels of inert particles and live aerosolised influenza virus, our findings show that surgical masks provide around a 6-fold reduction in exposure. Live viruses could be detected in the air behind all surgical masks tested. By contrast, properly fitted respirators could provide at least a 100-fold reduction. Surgical Masks and Respirators.Mycobacterium tuberculosis, the SARS virus, etc. Surgical masks (even those that meet Australian Standard AS 4381 for surgical masks) do not have adequate filtering and/or fitting attributes to provide effective respiratory protection for the wearer to this range of particle sizes.
