Notes: This is the CDC's guidance for hand hygiene to prevent the spread of COVID-19. "Hand hygiene is an important part of the U.S. response to the international emergence of COVID-19. Practicing hand hygiene, which includes the use of alcohol-based hand rub (ABHR) or handwashing, is a simple yet effective way to prevent the spread of pathogens and infections in healthcare settings. CDC recommendations reflect this important role." In a medical setting, the CDC recommends hand sanitizer over hand washing due to better compliance. 

Supports DESE Claim 1?: Somewhat. The CDC guidance encourages sanitizer over hand washing in healthcare settings, while the DESE document seems to favor hand washing as the preference.

Supports DESE Claim 2?: Yes. 20 seconds is the recommended amount of time for hand washing on the site.

Supports DESE Claim 3?: Yes
