Italy is currently experiencing an epidemic of COVID-19 which emerged in the Lombardy region. During the interval between Feb 25–29, 2020, we identified 46 cases of COVID-19 reported in 21 countries in Europe, Africa, North America, and South America that were either in individuals with recent travel from Italy, or who had presumed infection by a traveller from Italy.2 In six cases, in four of the affected countries (Switzerland, France, Austria, and Croatia), land travel was a likely route of introduction, or was documented to have been the route of introduction.
