Few sectors of the global economy are immune from pandemic-induced economic pain right now, but some find comfort in the fact they will bounce-back in the near or medium-term. The travel business, which has been brought to a standstill as billions of people have been forced to stay home, may not be one of those lucky industries. As social distancing will likely remain a reality until a COVID-19 vaccine is made available – a process that could still take 12-18 months – people's appetite to take foreign holidays is unlikely to bounce back in a big way. And many countries will keep their borders closed to non-residents for months to come, as fears of contagion persist. This is a huge blow for countries that rely on tourism to pump cash into their economies. Travel contributed a whopping $8.8 trillion to the global economy in 2018 and was responsible for 10.4 percent of all economic activity around the world.
