No. This is written ambiguously. It starts with
>As the virus continues to spread nationally
And then the numbers are listed as
>80% of the population may experience mild symptoms, such as fever or flu-like symptoms that they treat at home
If it were as you say, they would write x% of the infected population, or something to that effect. Then again, given all the incompetence I've witnessed lately across the news, it wouldn't surprise me if they ambiguously wrote it by mistake.
In any case, you'll note that China just shut down it's entire industry for two months over this. That's not something an authoritarian state does lightly. Especially considering it may, say, make it obvious that sending all of your production offshore to China is a national security threat.
Edit: Italian Prime Minister just made a 2AM press announcement of the Isolation of Lombardy. That's 16 million people. We're approaching the right ballpark here. 8% of the Iranian parliment have confirmed cases. Two are already dead. This is everything we've been warning you about.
