As described by Governor Cuomo, Dallas was the first major US city to see an Ebola case. This, in turn, allowed New York leadership to have some semblance of what methods did or did not work when trying to contain the disease. Moreover, the policy was implemented in response to the major Ebola outbreaks occurring at this time. This included those within Africa, Europe, and cases seen in Dallas. Moreover, the policy follows the city's "Safe-than-sorry" methodology discussed by Governor Cuomo; he, along with other state and city leaders, believed assuming an Ebola outbreak would occur within the state would give them the best chance of mitigating its effects and minimizing disease spread.
