The C.D.C.’s New Challenge? Grappling With Imperfect Science
The New York Times
The Omicron coronavirus variant is moving much faster than researchers can, worsening a longstanding problem: The agency must make tough decisions with scant data.
The Centers for Disease Control and Prevention was long revered for its methodical and meticulous scientific approach. Agencies in other nations modeled themselves after the world’s most highly regarded public health authority, even adopting the name.
At the outset of the pandemic, the C.D.C. moved at its accustomed pace. But this time, with a novel virus moving so quickly, the country paid a price: Testing and surveillance lagged as the agency tried to implement dated approaches with creaky infrastructure. Officials were late to recommend masking, in part because federal scientists took too long to recognize that the virus was airborne.
Now the contagious Omicron variant is pushing the C.D.C. into uncharted territory. Because decisions must be made at a breakneck pace, the agency has issued recommendations based on what once would have been considered insufficient evidence, amid growing public concern about how these guidelines affect the economy and education.
