That’s actually a low number. China numbers had 20% in an ICU bed.
For those in denial, that means if 10,000 people get this in a major metropolitan area, 1000 of them will need an ICU bed. No major metro areas have 1000 free ICU beds right now. Much less ‘isolation’ type beds.
Disaster.
Meanwhile, if you’re south of 32N latitude, you can officially make D3 (the best kind of D3) by going outside for 20-30m during midday, right around noon. Don’t burn, and make sure you aren’t on any meds that preclude sun exposure. Just ‘flip like bacon’ those parts that are exposed to the sun so you don’t over expose anything you’d rather not :) 20-30m is about all the sun exposure you need to make D3 as your body simply doesn’t make it once its capacity for production is ‘occupied’. So hours and hours won’t really raise your D3 over and above what 30m would have done anyways.

IIRC the ‘elevation’ number in that chart needs to be 50deg or higher to make D3.
