(CNN) - The Centers for Disease Control and Prevention will not revise its guidelines for reopening schools despite calls from the White House to do so, agency Director Dr. Robert Redfield said Thursday.
Instead, additional reference documents will be provided, Redfield told ABC's "Good Morning America."
"Our guidelines are our guidelines, but we are going to provide additional reference documents to aid basically communities in trying to open K-through-12s," Redfield said. "It's not a revision of the guidelines; it's just to provide additional information to help schools be able to use the guidance we put forward."
The comments risk further adding to a sense of confusion about how best to reopen schools as the new academic year approaches amid a surge in confirmed coronavirus cases. President Donald Trump has vehemently called for schools to reopen -- one of the keys to restarting the economy and getting the country back to a sense of pre-pandemic normalcy -- calling the existing guidelines "very tough and expensive," and going so far as to threaten to cut off school funding, though the federal government's ability to do so is limited.
During a press briefing on Wednesday, Vice President Mike Pence said the CDC would issue new guidance on reopening schools next week. Both he and Redfield said the agency's recommendations should not be viewed as a barrier to returning children to classrooms.
In response to comments about the guidelines being too tough or impractical, Redfield said Thursday this depends on how the guidelines are put together.
"Right now, we're continuing to work with the local jurisdictions to how they want to take the portfolio of guidance that we've given to make them practical for their schools to reopen," he said.
Current CDC guidelines for schools to reopen contain elaborate steps to keep children safe. They call for desks to be placed six feet apart when feasible and for children to face in the same direction on one side of tables and the use of cloth face coverings. The CDC suggests the closing of communal areas like dining rooms and playgrounds and the installation of physical barriers like sneeze guards where necessary. It proposes that staff who are at risk of Covid-19 complications because of health conditions could telework or be assigned other duties while children with medical conditions could learn online.
Given such advice, it was not clear how the CDC guidelines could be eased without raising the risk that the return to school could cause infections. The current guidelines say the highest risk of Covid-19 transmission could come with full-size classes, a lack of social distancing and with children mixing between lessons.
