Proof Of Authority & Safe Hand Sanitizer
The FDA reminds people to wash hands using soap and water for at least 20 seconds (especially after going to the public place and after coughing, sneezing etc.) to prevent the spread of the germs.
If soap and water is not available, CDC suggests using a hand sanitizer that contains at least 60% alcohol to kill disease-causing germs. *Alcohol less than 60% may not work effectively.
