Notice how they say "cases" not "deaths." This is a classic bait-and-switch.
The fact is, if the cases are in the billions, that's still not necessarily a big deal. It doesn't mean anything. The death rate is the real statistic to look at.
But, they push the "cases" as being high on the news to freak people out. Compare it to the "cases" of the common cold, though. How many people do you think had the common cold this past year? Probably a lot of people. But, how many died of it? Next to no one.
They're going to do this for a while, as the number of tests done rises. It's all fear porn.
