Did you go to the emergency room? Is that where you think the Covid patients are? They are separated and taken strait to ICU usually pllative care ICU which in most hospitals are on the upper floors. Obviously the covid patients aren't on display for all to see and be contaminated. I've been in the hospital 2 times in the last 4 weeks for a total of 6 days with heart problems. I know an ICU nurse and know our Covid wing is fu and all 14 vents are in use. They were on the 12th floor. I was in the emergency room. Telemetry. Post op operating room and finally on the 6th floor ICU. I didnt see a single covid patient either....which I am grateful for.
