Title: Nonmedical Masks in Public for Respiratory Pandemics: Droplet Retention by Two-Layer Textile Barrier Fully Protects Germ-free Mice from Bacteria in Droplets Document date: 2020_4_10
ID: e790rxq9_24
Snippet: The second phase of the experiment (repeated exposure with 10-times more droplets), with 116 12 germ-free mice, showed that the textile-EDB maintained all animals germ-free, even after 20 117 droplet sprays at 60cm, while mice located at 180cm became colonized by bacteria-carrying 118 droplets with a single spray (0/8 vs 4/4, Fisher's exact, p=0.002). Collectively, barriers protected 119 all mice (even with low textile density; heavy vs light fab.....

Collectively, barriers protected 119 all mice (even with low textile density; heavy vs light fabric, paired t-test, p=0.002) against high 120 droplet doses (2 or 20 sprays) if the EDB fully covered the cage (0/20 vs 10/10, Fisher's exact, 121
