COVID-19 is a global issue. The disease can be in every country and region, and nearly every city. That’s why health experts do not recommend any nonessential (无关紧要的) travel at this time. The US Centers for Disease Control and Prevention (CDC) said crowded travel settings, like airports, may increase chances of getting COVID-19, as there is increased risk of being exposed (暴露于) to other travelers who may be infected.
