Stanford Hospital is opening for elective surgeries. On the news last night they said they tested ALL the employees, 11,000 or so, and found 0.3% tested positive - that means 33 employees had it and didn't know it. 3% had antibodies Gotta love one of my great stock picks.... Google: I found the article about last night's news story:abc7news.com Thanks to mass testing, Stanford Medical Center was able to start non-emergency surgery Monday, providing relieve to patients in pain..... This week Stanford Medical Center has more than 800 procedures on the schedule, which is about 60% of the system's capacity. Dr. Hawn hopes Stanford will be back to 100% by June, which would mean about 1,350 weekly procedures... "What we've found from the 11,000 of our employees who we've tested, we've had .3% that actually have shown positive with COVID... At the same time we did the serology testing and less than 3% actually have the antibodies.... It really creates a safe environment for us to be able to say to the public... that this is safe. "If you do the math, that's just 33 employees who tested positive for COVID, and 330 employees who have antibodies, which means they had the virus in the past. Another element that has allowed Stanford to resume more surgeries, is their strong PPE supply. Entwistle says because of direct sourcing pre-pandemic in addition to several large donations, their hospitals have plenty of masks and supplies to keep their employees safe . I think the data says why the governor is allowing a slow opening and pushing hard to get people trained for contact tracing. Herd immunity is around 60% with antibodies that give immunity (we don't know yet how immune we are... can we get it again? etc.) so it is a factor of 20 to get from 3% to 60%... that number would probably overwhelm all the extra capacity they put in but didn't need.
