Face masks: benefits and risks through the COVID-19 crisis

”  These “cloth coverings” aren’t surgical masks or filtering face-piece respirators that are “critical supplies” that the CDC recommends be limited by use by healthcare workers. The CDC also provides advice for creating face masks from t-shirts (or coffee filters), cleaning cloth coverings inside washing machine, and properly removing cloth coverings from the face (avoiding touching your eye area or mouth, and immediately washing hands after removal).

Custom Mask

We conducted a fast review to investigate the impact breathing apparatus use has had to managing transmission of respiratory viral infections.A rapid review was conducted in keeping with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance. Five electronic databases (CINAHL, Embase, Medline, PsycINFO and Global Health) were searched from database inception thus far, using pre-defined keyphrases. We included all studies of the design and used descriptive analysis to report summary statistics of search results. Data were extracted including sample characteristics, study design, respiratory virus being controlled, sort of markers used as well as their effectiveness.

Leung and colleagues [5] screened greater than 3000 individuals and identified 123 patients being affected by a viral respiratory infection. The viral load inside exhaled aerosol and droplets were different depending on the etiology with the infection, but was exponentially reduced by surgical masks (cat. no. 62356, Kimberly-Clark). More viral particles were released through coughing. Generally, the authors reported a notably higher viral load in nose swabs in comparison with throat swabs. This data used on influenza, corona, and rhino virus. No data are available for SARS-CoV-2 yet.
