The accelerating reopening of businesses in the U.S. doesn't violate "the science" of COVID-19. Some individual scientists are warning of increased virus deaths associated with these choices. But there's no science that can tell us precisely how to balance public health with other human needs.
Some people want to minimize COVID-19 cases at all costs — but that's a moral stance. It's not "the science."
Yet as tension grows over governors' decisions to reopen restaurants, gyms and other venues, Rochelle Walensky, director of the Centers for Disease Control and Prevention, not only warned that the U.S. could see a surge in new cases, but also pleaded with Americans to continue with public health measures like masks, solitude and avoiding travel. This sort of public health advice conflates science, morality, values and partisan politics. We've seen too much of it in the past 12 months.
Risk communication consultant Peter Sandman made the distinction this way: "I am simply not interested in an epidemiologist's opinion on whether schools should be reopened. I'm interested in an epidemiologist's opinion on how much more the virus will spread if schools are reopened. Whether schools should be reopened — that's not their field."
University of California, San Francisco, physician Vinay Prasad took a similar view. "Science can only articulate our best estimate of what would happen if we did something, or if we did something else. But science can't tell you how to value those things. Those will always be decisions for the body politic."
At this point most people know the vaccines aren't perfect. But the signs are everywhere that many people think they're good enough to return to travel, restaurants and other activities. That means public health officials need to be more specific and less draconian.
Sandman says he thinks the public health community is still compensating for the early 2020 blunders downplaying COVID-19's risks. "I think when they realized their mistake they overcompensated and became excessively pessimistic instead," he wrote me in an e-mail this week.
He sees this in the way they're still recommending that fully vaccinated people shouldn't travel, and the long months it took to allow public schools to open with a more realistic 3-foot social distancing rule.
