The evolving science clearly implicates that the primary mode of transmission of Covid is through the air and not from contact with surfaces. I think it is safe for you to take a cookie, as long as you know you are among respectful coworkers who have not coughed upon the cookies! However, the lesson is where you choose to eat the cookie. We have learned that the break room, lunch room, etc. or any common space where many people congregate over time and have poor ventilation are the places where viral infections occur—through inhaling other people’s exhaled breath. So, do not remove your mask in the lunch room to eat the cookie! I frankly believe that eating in the lunch room (breakroom, etc.) should not be allowed for the next few weeks while we are experiencing this sharp tremendous rise in delta and omicron viral infections.
