Basically, an ill patron vomits in the restaurant. Although an employee applied spray disinfectant, 36 patrons still contracted the virus. "A point-source norovirus outbreak occurred after an infected patron vomited in a restaurant. Transmission near the vomiting event likely occurred by aerosol or fomite. Norovirus spread throughout the restaurant could have occurred by aerosol, person-to-person, fomite, or foodborne routes. Inadequate employee handwashing likely facilitated foodborne transmission through servings of pecan pie." Norovirus is highly infectious and transmits easily in the environment.
So if you are in an eating establishment and someone vomits, consider leaving immediately. For the food establishment, move people away from event, clean like heck following established protocol, and consider giving the cleaner the rest of the night off.
