 
The COVID-19 pandemic has impacted the tourism industry due to the resulting travel restrictions as well as slump in demand among travelers. The tourism industry has been massively affected by the spread of coronavirus, as many countries have introduced travel restrictions in an attempt to contain its spread. The United Nations World Tourism Organization estimated that global international tourist arrivals could have decreased by 58% to 78% in 2020, leading to a potential loss of US $0.9–1.2 trillion in international tourism receipts.
In many of the world's cities, planned travel went down by 80–90%. Conflicting and unilateral travel restrictions occurred regionally and many tourist attractions around the world, such as museums, amusement parks, gyms and sports venues closed down. After March 2020, tourist firms' connectivity has skyrocketed. Restaurants are the most significantly impacted subsectors of tourism, followed by airline firms. UNWTO reported a 65% drop in international tourist arrivals in the first six months of 2020. Air passenger travel showed a similar decline. The United Nations Conference on Trade and Development released a report in June 2021 stating that the global economy could lose over US$4 trillion as a result of the pandemic.
Tourism under the pandemic.
Some people have taken advantage of airlines drastically reducing their fares to travel for leisure despite multiple warnings to remain at home, along with two-week self-quarantine requirements upon arrival or return from travel. A number of college students tested positive for COVID-19 after returning from traditional spring break destinations such as the Florida beaches, South Padre Island, and Cabo San Lucas.
Dubai received global scrutiny for opening tourism too soon, despite a high rate of COVID-positive cases detected in the emirate. At least 300,000 people travelled to and from UAE and the U.K. in the months of November and December 2020. In the early months of the pandemic, the situation was reportedly handled well by the emirate. However, around New Year's Eve tourists and locals were reported to be attending parties without social distancing or face-masks. Accusations that Dubai was acting as a "super-spreader" of the virus, forced authorities of the emirate to close all bars and pubs for a month on 1 February 2021.
Tourism and vaccination.
Many tourism venues such as museums, visitor centers, restaurants and hotels mandated COVID-19 vaccination for their staff or visitors, and such venues were known as "vaccinated venues". Research has shown that tourists have varying levels of belief on COVID-19 vaccination in terms of its effectiveness and side effects, which have impact on the preferences of tourists to preference to visit or use "vaccinated venues".
Travel restrictions.
As a result of the pandemic, many countries and regions have imposed quarantines, entry bans, or other restrictions for citizens or recent travellers to the most affected areas. Other countries and regions have imposed global restrictions that apply to all foreign countries and territories, or prevent their own citizens from travelling overseas without good reason.
Together with a decreased willingness to travel, the restrictions have had a negative economic impact on the travel sector in those regions. A possible long-term impact has been a decline of business travel and international conferencing, and the rise of their virtual, online equivalents. Concerns have been raised over the effectiveness of travel restrictions to contain the spread of COVID-19.
