When their is a global infectious disease outbreak, one action governments take is traveler screenings--we saw it during the 2014 Ebola outbreak and we are seeing it with the current COVID-19 outbreak.

My guest today addresses this issue in a recent study published in eLife.

Joining me is Katelyn Gostic, PhD. Dr Gostic is with the Dept. of Ecology & Evolution at the University of Chicago and the lead author of the study.
