Homemade masks made of a double layer of tea towel cloth are not only protecting others but also protect yourself nearly as effectively as N95 masks.
The original research was made by PHE - Public Health England and the results are:
B atrophaeus - ~1um :
Surgical mask 96.35% filtering
Double layer tea towel 96.71% filtering
Bacteriophage MS2 - 23nm :
Surgical mask 89.52% filtering
Tea towel one layer 72.46% filtering
The full paper is on researchgate, title:
"Testing the Efficacy of Homemade Masks: Would They Protect in an Influenza Pandemic?"
Also every super market should have the use of hand sanitizer obligatory at the entrance.
There is a pretty good video for simulations of the epidemic spreading [1] - it is not going to stop until we either have a vaccine or ~60% of the population have antibodies. So the choice is to sit the next 12-18months at home or we fight the transmission of the virus.
Masks cost nothing compared to the economic disaster that we are running into. The virus spreads via mouth and nose and secondary via the hands. So just stop it at the source.
