As best as I am aware, minimizing indoor contact of extended periods of time is by far the most critical precaution for minimizing the transmission of the Wuhan (“COVID”) virus.
Hand sanitizer would probably fall near the bottom of the list of priorities here. Consider:
– Hand sanitizer should only be resorted-to when thorough washing with soap and water (preferably warm) are not available;
– One should not touch one’s face or food at any time without first assuring that one’s hands are properly clean or donning clean gloves (that have not been contaminated by handling);
– Shaking hands and other forms of physical social contact should be altogether avoided.
