Communities, companies and individuals experience the disruptions in different ways and at different times. In the US, as late as March 18—a full week after Italy’s crisis had become dire, days after six California counties had been given the order to shelter in place and the day after Ohio canceled its primary elections—some citizens could be heard complaining about the overreaction, others were still decrying the massive hoax being perpetrated, and others were simply wishing away the situation and attempting to maintain a normal schedule. In other words, while some were still in the first stage, others were entering (if not well into) the fourth stage.
