It seems We already accepted stay home, social distancing and mask as grants to avoid Covid 19 infection. But, it has to be noted that droplets transport in the air depends on many environmental factors of which wind speed and direction as well as temperature can be considered. Also, if touching eye with unsafe hand can lead to infection then how is eye protection considered?
What do you think on the relevance of interdisciplinary research approach, including engineers?
Scholars your ideas are welcome!
They are very unscientific. When the measures were installed there were no studies to back them up. Politicians are not scientists. They have to do something, even if their actions do not make sense at all.
Until getting the vaccine or treatment prevention is better than cure.

It concluded that 'eye protection might provide additional benefits'.
While there is enough evidence to demonstrate that wearing masks of different types reduces spread in the community and in health care settings, the evidence for elaborate personal protective equipment (PPE) giving added advantage is weak. According to author's conclusion of this Cochrane review, there is low‐ to very low‐certainty evidence that covering more parts of the body leads to better protection but usually comes at the cost of more difficult donning or doffing and less user comfort.
