Varadero, Cuba's iconic resort city, stands completely devoid of tourists amid the coronavirus pandemic on March 4, 2021.
Governments initially started easing travel restrictions last year but reversed the trend after new virus strains emerged and because of "the persistent seriousness of the epidemiological situation," the Madrid-based World Tourism Organization said in a report. That is down from the peak in May 2020 when 75 percent of destinations worldwide were completely shut, but up from November when 27 percent were closed.The UN body said there was a trend towards a "more nuanced, evidence and risk-based approach" to travel restrictions, such as requiring international tourists to provide a negative test on arrival.
