"אולי לא עוזר" - אם עוטים על הסנטר.
נתחיל מא-ב, אדם נגוע ממלא את האויר סביבו בחלקיקי רוק נגועים בזמן דיבור ונשימה, בשיעול ובעיטוש הוא מפיץ את הנגיף למרחקים, המסכה פשוט מונעת את ההפצה.
אולי זה לא הרמטי, אך מועיל בהקטנת ההפצה בעשרות אחוזים. |

עזוב, הוא כאן לא כדי להקשיב לדון ולהגיע למסקנות.
הוא כאן בשביל לשווק את הגישה של בעלז.
אגב, הוא אינו מכחיש שהוא 'לומד שם ומסתובב שם'.

הבאתי לך ציטוט מאתר הארגון הבריאות העולמי.
יש לך מה לענות?

פשוט תביא את שאר הציטוט - לפחות החלקים הרלוונטיים. זה לא כ"כ קשה:
However, for areas of widespread transmission, with limited capacity for implementing control measures and especially in settings physical distancing of at least 1 metre is not possible – such as on public transport, in shops or in other confined or crowded environments – WHO advises governments to encourage the general public to use non-medical fabric masks.
WHO recomms that people always consult local authorities on recommed practices in their area.
If there is widespread community transmission, and especially in settings physical distancing cannot be maintained, governments should encourage the general public to wear a fabric mask. WHO also provides details on the composition of a fabric mask and how to safely wear one.
For countries that are considering the use of masks, WHO advises decision-makers to apply a risk-based approach to decide , when and what type of masks should be used. WHO advises decision makers to consider the following:
Purpose of mask use: if the intention is preventing the wearer transmitting infection to others (source control) or to offer protection to the wearer against infection (prevention).
However, there are some settings in which it may not be possible to keep physical distancing and the use of a mask could be helpful to provide a barrier to limit the spread of potentially infectious lets someone who is infected. In addition, there is some evidence which suggests that some infected people without showing symptoms may be able to transmit the virus others. For this reason, WHO advises that governments should encourage the use of non-medical fabric masks, which can act as a barrier to prevent the spread of the virus the wearer to others there are many cases of COVID-19, for people in the general public physical distancing of at least 1 metre is not possible – such as, on public transport, in shops or in other confined or crowded environments.
