A new report says the coronavirus pandemic caused a 65 percent decrease in international travel during the first six months of 2020. The World Tourism Organization, an agency of the United Nations, published the report on Tuesday. It noted that the drop in international travel resulted in a loss of $460 billion in export revenues from tourism. The loss is five times greater than the loss recorded in 2009 during the international financial crisis. The organization said in a statement that the U.N. agency estimates it will take between two to four years for tourist arrivals to return to 2019 levels.
