On June 25, 2020 the UNESCO hold a Cities Platform online meeting and discussed various cities’ responses to COVID-19. There was also a special panel which focused on the pandemic’s impact on urban tourism:
As the COVID-19 crisis unfolds, it has had an unprecedented impact on travel with the closing of virtually all destinations worldwide. Tourism was a major source of growth, employment and income for many of the world’s developing countries with over 1.5 billion people crossing international borders in 2019. Yet, millions of jobs in the travel and tourism sector are being lost every day and up to 120 million are under immediate threat.
