I went into the office Tuesday/Wednesday this week. I had a study monitor visit yesterday. Someone at the front desk was informed her BIL that she sat beside at a luncheon on Sunday tested positive for the virus. She told the manager who told her to keep her mask on. They eat in the board room where of course she takes off her mask. They don't know yet if she is positive but this is how it spreads because people don't want to be inconvenienced!
