How does the coronavirus spread?
Human-to-human transmission of SARS-CoV-2 is efficient, and infected persons can transmit the virus even when they have no, or only mild symptoms. Because no antiviral drugs or vaccines are available, virus containment and prevention of infection are the current highest priorities. To limit virus spread, effective hand hygiene is crucial. Therefore, easily available but efficient disinfectants are needed.
The CDC recommends frequent handwashing with soap and water for at least 20 seconds for the prevention of COVID-19. However, hand washing is not always possible, especially when there is no access to running water and soap.
When hand washing is not possible, the CDC recommends using a hand sanitizer with at least 60% alcohol. 
To limit virus spread, effective hand hygiene is crucial.
South Korea has done well in its fight against Coronavirus, partly due to its citizens already being used to wearing face masks and using hand sanitizers
Earlier this month a shipment of 115,000 bottles of hand sanitizer was headed to King County, WA from South Korea to help in the fight against the Coronavirus.
King County officials said the hand sanitizer will go to first responders, health care workers, and others fighting the virus.
