The study examined the relationship between perception of COVID-19, travel risk perception and travel behaviour among travellers in the DACH region (Germany, Austria, Switzerland)–an important tourism market and, after Italy, the second region in Europe that was impacted by COVID-19. Data were collected at two points of time: the sample of the study in Period 1 (n = 1158) was collected at a critical point in time in the beginning of March 2020, when Italy was already massively affected by COVID-19; the sample of the study in Period 2 (n = 212) was collected two weeks later, when Europe has seen immense impacts and COVID-19 was declared a pandemic. Cluster analysis was performed and defined three unique clusters in both periods with distinctive characteristics. In addition, results revealed a significant increase in risk perception of COVID-19, travel risk perception and travel behaviour over a short period of time. © 2020 Informa UK Limited, trading as Taylor & Francis Group.
