Not all experts are saying this. CDC organizations in different countries recommend wearing masks.

I think mainly this was to prevent supply problems. But we don't all need to wear medical grade masks to gain the benefits.

You may never show symptoms and still spread it. Everyone should be wearing masks in public, if you must be out and near anyone else. The title of the post says it all.

I think this should be taken with a grain of salt. You can't be physically shedding large quantities of virus if you are not coughing or sneezing, and being exposed to large quantities is essential for infection.

Which experts in the western countries because of shortage of masks they have spread this false narrative that masks don't work. Masks work they won't 100% of the time but even if they work 50% the spread of the virus halves.
