"The White House has decided not to trace the contacts of guests and staff members at the Rose Garden celebration 10 days ago for Judge Amy Coney Barrett, where at least eight people, including the president, may have become infected"

"It has limited its efforts to notifying people who came in close contact with Mr. Trump in the 2 days before his Covid diagnosis Thursday evening. It has also cut the CDC, which has the government’s most extensive knowledge and resources for contact tracing, out of the process."

"Any of the closely packed guests and staff members at the Rose Garden ceremony could have gone on to transmit the virus to many others,

so the White House’s decision not to investigate the cluster of infections, and pinpoint the source, has potentially devastating consequences for hundreds of people, several experts warned."

"Even the contact tracing efforts within the two-day window have been limited, consisting mostly of emails notifying people of potential exposure, rather than the detailed phone conversations to warn anyone who may have been exposed,

coach them on which symptoms to look for and counsel them to isolate if they do begin to show symptoms.

“I guess an email is notification of exposure,” said Erin Sanders, a nurse practitioner and certified contact tracer in Boston. “But that is not contact tracing,” she said, “and not how a responsible public health agency handles a super-spreading cluster of a deadly virus.”

Instead of the CDC: "the tracing efforts are being run by the White House Medical Unit, a group of about 30 doctors, nurses and physician assistants, headed by Dr. Sean Conley, the White House physician, who has been the public spokesman for Mr. Trump’s doctors."

Experts at the C.D.C. could have immediately put in place contact tracing for President Trump and others who have been infected, working with health departments of the states to which Mr. Trump and others have traveled. But regulations require that the C.D.C. be asked to step in.

“We don’t get involved unless we’re asked to get involved,” said a federal official who asked not to be identified because he was not authorized to speak about the matter."

"Some experts said they were particularly worried about the cooks, gardeners, security guards, stenographers, cleaning crew and others who tend to be forgotten."

“It’s not just the 400 people that work in the White House. It’s their families that they go home to, it’s who they may have been in contact with, their children” and the children’s contacts at school, he said.

“The need for extensive contact tracing, if for no other reason than to protect vulnerable communities that are second or third degree removed, is massively important.”
