The Centres for Disease Control and Prevention has repeatedly found its suggestions for fighting the coronavirus outbreak taking a backseat to other concerns within the Trump administration. That leaves public health experts outside government fearing the agency’s decades of experience in beating back disease threats are going to waste.

“You have the greatest fighting force against infectious diseases in world history. Why would you not use them?” said Dr. Howard Markel, a public health historian at the University of Michigan.

The complaints have sounded for months. But they have become louder following repeated revelations that transmission-prevention guidance crafted by CDC scientists was never adopted by the White House.
