Title of this thesis is „The Impact of COVID-19 virus on Global and National Tourism“. Tourism and its importance for the global and national economy is extremely significant. The outbreak of the COVID - 19 pandemic has caused an unprecedented crisis and disturbances around the world, and poses a special risk to tourism employees. Until the declaration of the pandemic, global tourism was among the leading economic sectors in the world and the driver of its growth and development. In Croatia, it also played a significant role. Due to the pandemic, since February 2020, strict restrictions on the movement of people have been introduced in most countries of the world and airlines have been suspended, borders have been closed and transport (especially by air) has been restricted. Changes in trends and conditions in global and national tourism have been drastic. Negative trends are also reflected in other sectors of the economy with which tourism is more or less connected. The approach to tourist supply and demand has changed (changes in trends and expectations of tourists). Theoretical research on changes in the way of behavior and preferences of tourists or new trends ("new normal") as well as expectations from tourism in the future were investigated. The research methods used in the preparation of the final paper were descriptive and historical methods of analysis and synthesis. It turned out that tourists, despite the fear of infection and restrictions and bans, want to travel as soon as health conditions improve or remove the restrictions and risks that accompany travel due to a pandemic. The main recommendation to the Government of the Republic of Croatia is to reduce Croatia's dependence on tourism and invest in other economic sectors.
