The unfolding situation precipitated a series of increasingly stringent containment measures. By the end of the first day, the Expert Committee issued a travel advisory restricting travel in 16 Denver Metro counties. But, one person noted, "the public was not [heeding] the voluntary travel advisory." Some people, in fact, were reported to be racing out of the state. As part of the travel advisory, persons were advised to stay home unless they were close contacts of diagnosed cases or were feeling sick, in which case they were directed to seek medical care. As one observer noted: "They told 1 million people to stay in their homes. How would we have enforced this?" When asked what would be possible if the situation actually required it, the police and National Guard responded to the Expert Committee that they would be unable to keep people at home. Another participant commented that by the end of the exercise, "people had been asked to stay in their homes for 72 hours...How were they were supposed to get food or medicine?" "With borders closed, how were we planning to feed 4 million people?...Many of the control measures ordered were delusional." http://www.hopkins-biodefense.org/pages/news/quarter2_2.html
