FYI if you had Norovirus you’re contagious for roughly 2 weeks and the virus survives hand sanitizer/alcohol. Washing your hands is the only way to prevent the spread

Unsure if people realize this but it’s pretty damn important that if you touch any surface out in public to not touch your face or food until you can wash your hands thoroughly for 30 seconds. Norovirus is extremely hard to kill with rubbing alcohol, hand sanitizer and UV lights not able to kill it. The only way for you to stop the spread and to try not to catch it is to just wash your hands.

EDIT: The virus can also survive on surfaces for a good while. I personally try to use a napkin or paper towel to open a door.
