>>11120482please help with the data collection.
i am trying to correlate mask wearing with viral transmission. i do not need more information of droplet or aerosol exhaust physics. just correlation: mask/death rate.
Data from europe and north america correlate mask wearing with fear of covid but not with cases or mortality rates. any further data would be helpful.
