I find it extremely interesting that this article was originally written on Jan 31, 2020. I know because I booked marked it. Now going back to re-read it, the on-line date has been changed to March 26, 2020.

It was known on 1/31/2020 how this virus is transmitted and what measures were needed to be taken in order to slow the spread.
If this had been taken seriously then, we would not be in the situation we are now. It was ignored by the administration. I am not usually a conspiracy theorist, but this makes me question why the Trump administration did not take the information seriously when it was first available in January. I found the article about 2 weeks ago. I also wonder why the date of the article has been changed.
