Common sense implies that they must be at least partially effective at reducing transmission of various diseases, in the same way that wearing gloves does (i.e. a barrier is created which partially blocks movement of potentially harmful particles).
Common sense also implies that masks will inevitably get dirty and will harbor pathogenic bacteria in a warm moist place contaminated with food and in close proximity to child’s face. Covid aside, this seems like a net negative from common sense perspective.
