Large scale government lockdowns may have started in late March. By the beginning of March, corporations, local governments, and people were starting their own lockdowns. I had a 3 day business trip in early March. I wasn't sure if it was going to be cancelled because of the virus. Both flights weren't even half full. Security lines were either almost or entirely non-existent. In Philly, traffic was significantly less and far fewer people in restaurants than previous visits. Before I got home, local schools were already starting close. From my point of view, everything started at the end of February or very beginning of March.
