This has already been an intense year for norovirus. According to the CDC, positive tests for the illness peaked at 16 percent in January and the season still has time to go — the virus typically peaks sometime between November and April. Relative to other seasonal illnesses, norovirus is highly infectious and spreads easily, particularly in spaces like restaurants. An infected person can shed billions of particles from the illness, while just a few particles can make someone else ill. As a result, norovirus passes easily through even brief contact with others, by touching contaminated surfaces or consuming contaminated food or beverages. Make sure your staff illness policies not only enforce the sanitation practices required to keep illnesses at bay, but also ensure staff with symptoms of norovirus aren’t allowed to work and create a larger number of absences on your team.
