This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
We examine the relationship between incoming international passengers and COVID-19 case or death counts during the first wave of the pandemic in the U.S. We find passengers from Italy, but not China, were an important source of exposure, and thus increased the early spread of COVID-19 in the U.S. These results suggest stopping travel from Europe earlier likely would have had greater impact on reducing the spread of the virus in the US, compared to the earlier ban on travel from China. Further, banning travel from pandemic hotspots may be smart policy, depending on the specific characteristics of the virus.
