I think the point is we didn't know this was a thing before January. Now that we know, we can better prepare for it. Right now its spreading like wildfire, and we need to contain the spread as it is already overwhelming healthcare infrastructures worldwide.
Want to be clear here: We knew this was coming. We had dress rehearsals with SARS, MERS, and H5N1. We knew what needed to be done. We just decided not to listen, and not to prepare.
This is the logical outcome.
Sorry, but I believe strongly that Reality exists and facing one's errors is critical to ensuring they don't happen again. The problem isn't that "we didn't know" the problem is people willingly choose to ignore facts.
Bingo! All these denialists are doing is adding to the problem. If more people had listened and understood how serious this was in the beginning we wouldn't be in this fucking mess
