CNN reports:

Shortly after joining the White House as President Donald Trump’s pandemic adviser, Dr. Scott Atlas launched a quiet effort that seemed counterintuitive to some of his colleagues — encouraging officials to limit Covid-19 testing mainly to people experiencing symptoms.

Atlas, a neuroradiologist, not an infectious disease expert, strongly supported a decision in August to revise federal guidelines to de-emphasize the need to test people without symptoms, according to two sources familiar with the process. He shared his view with state officials, including Republican Gov. Ron DeSantis and several others in Florida, according to transcripts of public events and accounts from private meetings in that state.

During a joint tour on August 31, Atlas and DeSantis urged public health officials in several Florida cities to focus less on universal testing and more on opening the economy and schools. In private and public meetings, according to transcripts and personal accounts, the two spoke in favor of testing people for Covid-19 primarily if they’re experiencing symptoms, a controversial view among epidemiologists. 

“The purpose of testing is to stop people from dying,” Atlas said during one stop, captured on video. “When you start introducing closure of schools because people have positive, asymptomatic tests, that’s sort of not the purpose of testing.”   

“I think, Dr. Atlas, we’re in agreement on focusing strategies in school on people who are symptomatic,” DeSantis said in another joint news conference that day. 

Their push to de-emphasize tests coincided with a dramatic drop in testing across Florida, even as the country was careening toward a fall coronavirus surge. A CNN analysis of the Florida state official numbers, aggregated by the Covid Tracking Project, shows that testing dropped off at the end of July and early August, with a peak seven-day average over 90,000 tests per day on July 18. Six weeks later, in early September, the seven-day average dropped by nearly half, with fewer than 48,000 tests per day, and hovered between there and 60,000 during the fall.

If Atlas and DeSantis’ advocacy in Florida is, in fact, responsible for the state’s testing decrease, that would be in keeping with the wishes of Trump, who for months has falsely suggested that the US has so many coronavirus cases only because it conducts so many tests. In June, Trump even said publicly that he wanted to “slow the testing down, please.”   

Though both Atlas and DeSantis declined to discuss their views with CNN for this story, they have articulated them in public.

Some state and local officials believe the pair was influential in taking Trump’s anti-testing pronouncements and helping to turn them into public policy. And the drop-off in testing is of deep concern to some. It took place as positivity rates remained high, in the range that the Centers for Disease Control and Prevention considers indicative of high community spread.

Asymptomatic Covid-19 carriers are still contagious, experts say. A lack of widespread testing makes it harder to map the disease as it spreads and to warn those at risk of illness.  [Continue reading…]
