1/ Many are arguing with me that the very small possibility of asymp/presymp transmission is still non-zero. So I want to point all of you to the CDC's reasoning for recently reducing quarantine to 10 days (sorry, caps are theirs): "ACCEPTING THERE IS A SMALL RESIDUAL RISK...
2/ "THAT A PERSON WHO IS LEAVING QUARANTINE EARLY CAN TRANSMIT TO SOMEONE ELSE IF THEY BECAME INFECTIOUS. THOSE RISKS ARE AS FOLLOWS — IN THE SITUATION WHERE QUARANTINE IS REDUCED TO TEN DAYS, WE CALCULATE THAT...
3/ "THE RESIDUAL RISK IS ABOUT 1% AND THAT THE UPPER LIMIT OF THAT RISK IS ABOUT 12%."
So the CDC formally accepts that small risks of transmission are acceptable because there are trade-offs to reducing the risk to zero.
4/ It's not a big leap to conclude that the demonstrably small risk of asymp/presymp transmission in casual public settings does not require mitigations like lockdowns and mask mandates.
I'm struck by the reassuring and matter-of-fact tone throughout this article from 2009 about swine flu in Mexico and how different it is from COVID reporting. It's about Mexico reopening after a 2-week lockdown.
"A report by the Centers for Disease Control and Prevention said America's two swine flu deaths - a toddler and a pregnant woman who both died in Texas- each suffered from several other illnesses when they were infected with the virus."
"[WHO] said...it is possible that a third of the world's population, or about 2 billion people, could become infected if this outbreak turns into a two-year pandemic. Independent experts agreed that the estimate was possible but pointed out that many would not show any symptoms."
1/ Dr. Jay Bhattacharya, @MartinKulldorff, and @SunetraGupta argue in this essay that there IS a middle ground between lockdowns and a "let it rip" approach."
They also offer specific ways to protect the vulnerable 👇
2/ "The aim of focused protection is to minimize overall mortality from both COVID-19 and other diseases by balancing the need to protect high-risk individuals from COVID-19 while reducing the harm that lockdowns have had on other aspects of medical care and public health."
3/ "Standard public health practice regularly seeks creative ways to protect vulnerable people from a host of diseases and conditions that threaten them, and COVID19 should not be an exception... These include,
e.g., frequent on-site testing...
