I'm an anesthesiologist, not an ID or epidemiology expert, but I read a lot...
In my honest opinion, testing doesn't really matter at this point. It will help divvy up resources and give us ideas of how we're doing, but the goal is prevention. Stop traveling, old people stay at home, cancel elective things, work from home, etc. That's the only way to curtail this. This testing stuff is a bunch of drivel to weaponize politically. The CDC probably screwed this up from the beginning, but before they even knew what was going on it was already spread due to the incubation period.
Italy is in a **** storm because they have one of the world's oldest average populations, and they got behind the 8 ball quick. I'll post the link soon, but they're essentially telling their critical care doctors to triage people and decide who gets their few resources, let the rest (old and sick) die. They pulling retired doctors and nurses back. They're using their operating room ventilators as ICU rooms/beds and cancelling all surgeries.
I have no earthly idea if we're looking at 100 deaths or 1,000,000 deaths, but I do not think that any precautions anyone is taking are over the top. The only way to stop this is containment and prevention. Only way to know if that is going to work, is, well, to touching do it.
There's a ton of people out there who are so mad that this is getting a lot attention, calling people chicken little, etc, and I don't touching get it. I ***HOPE AND PRAY*** that this is overblown. I seriously do.
Because if it's **anywhere** close to what some of the models predict, we're going to be so touched it's not even funny. People you know will die. Parents, grandparents, children. Some of those people won't get the care they need because hospitals will be overcrowded. Heart attacks will get missed. Strokes won't get treatment. Hell, more flu patients will die.
I seriously hope and pray all you touching know it alls who are too cool to get worried about a pandemic are right. Because if you're not some of us are going to be dead.
