Personally, I think looking at the numbers makes me feel better.
Looking at South Korea for example (because they have a large outbreak, test a lot of people, and are very transparent with their numbers): If I take their confirmed cases, and even multiply that by the 100 (because of missed cases/ more cases reported daily) and divide by 51 million (their population. It’s still only .85% of their population. And remember that’s 100x their actual confirmed cases. And 80% of those would presumably be mild cases.
If I did a similar calculation for China, the hot bed epicenter of this worldwide outbreak, only I’ll multiply their reported cases by 1000(!) , because who knows how accurate their numbers really are, it comes out to 5.7% of their population.
So yes, it will spread, but so many cases will be mild. And it’s not going to completely overwhelm our healthcare system like wildfire, as long as we don’t overwhelm it with fear.
