Before we listen to today’s clip, let’s have a look at some of the important vocabulary. First off, a “scourge” is something that causes great suffering or a lot of trouble. Then we have “to estimate”, which is to guess the amount, size or value of something. Next up, we have to “drive” something, which in the context of the story means to cause or to make something happen. You’ll hear it today in the form “driven by”, which you can think of as “caused by”. The next word, “transmission”, describes the process of spreading an illness from one person to another. Illnesses that can be spread in this way are called “infectious”, which is the next word to listen for. Next we have to “take off”, or to quickly become big, important or serious. When something is “fatal”, it causes death. And then there’s “significant”, which is another way of saying large, important and noticeable. The last one for today is “to withdraw”, to take away or to remove something.
All right, and with that, let’s listen to the story.
