[OC] Without 'curve flattening' (from shelter-in-place and testing), ICU beds in California will run out in a few weeks based on the current mortality trends. Data are modeled from JHU COVID19 mortality data up to 22Mar2020. I used mortality since the data for COVID19 positive infection is lacking.4yr ⋅ ivoidwarranty ⋅ r/CoronavirusCA
