Asymptomatic test pos. rate @UCSFHospitals now 6.2%. That’s 1-in-16 w/ no symptoms of Covid who test positive. In a crowd of 150 folks (ie, plane @SFO), there’s a 99.993% chance at least 1 person has Covid. Might⬆masking if flight attendant showed a sign saying that at boarding. https://t.co/n3fICuJRY6
