The last ten days appear to have shaken the world in general. News junkies will have been aware of COVID-19 since the beginning of the year. I made some long flights to and from in the US in late January, 我戴了口罩, even though only a couple of cases had been diagnosed in the US and none in Latin America. 我不是唯一一个这样做的人，也许每20个人中就有一个人这样做. 然而, 世界卫生组织3月11日宣布正式爆发流感大流行的同时，全球股市开始下跌. These came only a day or two after the first two positive cases were identified here in 玻利维亚. 玻利维亚宣布来自欧洲的航班停飞, with the last one arriving Friday the 13th in the morning.
