Thread -Pls RT- 🚨New #COVID19 paper🚨

We all know the stories of people✈️to Ischgl⛷️ and returning home🤒with #COVID19

economics.ku.dk/research/publi… Why should the timing of the school-breaks matter? #vinterferie #sportlov✈️⛷️

The number of Covid-19 cases was in the single-digits in early February 2020.
