  https://www.yalemedicine.org/news/norovirus-stomach-flu-cases-are-surging-3-things-to-know

  Prevention includes washing your hands frequently with soap and water; hand sanitizer doesn’t work as well. […] The main means of transmission is exposure to contaminated food, water, or surfaces, so the most important preventive strategies include disinfecting surfaces, heating food to sizzling temperatures, washing clothes in hot water, and washing hands frequently (that means soap and water, since hand sanitizer doesn’t work well against norovirus). […] Proper handwashing is key to preventing a norovirus infection. That means washing hands frequently with soap and water, especially before eating or handling food, before giving or taking medicine, and after using the toilet or changing a diaper. […] Hand sanitizers don’t work well for this virus. Norovirus has a capsule around the virus that protects it against most routine disinfectants, such as alcohol-based, hand-sanitizing gels. But vigorous washing with plain soap and water for 20 seconds creates friction that better washes away the viral particles.

• #7 Norovirus – Wikipedia

  https://en.wikipedia.org/wiki/Norovirus

  Prevention involves proper hand washing and disinfection of contaminated surfaces. […] Hand washing with soap and water is an effective method for reducing the transmission of norovirus pathogens. Alcohol rubs (≥62% isopropyl alcohol) may be used as an adjunct, but are less effective than hand-washing, as norovirus lacks a lipid viral envelope. […] Surfaces where norovirus particles may be present can be sanitised with a solution of 1.5% to 7.5% of household bleach in water, or other disinfectants effective against norovirus. […] In healthcare environments, the prevention of nosocomial infections involves routine and terminal cleaning.
