Erroneous and reversed coronavirus guidance from the nation’s top health agency amid reports of tampering from Trump administration officials is « deeply concerning » and could « ruin the credibility » of the agency, Dr.Â Scott GottliebÂ told CNBC on Tuesday.Â
The Centers for Disease Control and Prevention acknowledged on Monday it erroneously posted draft guidanceÂ that said the coronavirus spreads through airborne particles thatÂ can remain suspended in the air and travel beyond 6 feet. The changes came as global health officials at the World Health Organization said there’s no « new evidence » onÂ airborne particles.Â
« It’s really hard to believe that this was an accidental posting of draft guidance that they had to subsequently pull down 48 hours later that they didn’t realize they had put it up over the course of the weekend, » said Gottlieb, former Food and Drug Administration chief in the Trump administration.
The CDC’s error on Monday came only days after it reversed controversial coronavirus testing guidance on its website that said peopleÂ who wereÂ exposed to an infected personÂ but weren’t showing any symptoms did « not necessarily need a test. » The CDC called the update a « clarification » amid reports from The New York Times that the guidance came from Trump administration officials rather than CDC scientists. The Times cited people familiar with the matter and internal documents.
Those reports follow similar accounts first reported by Politico earlier this month that communications aides in the Department of Health and Human Services requested and received the ability to review and seek changes to theÂ Morbidity and Mortality Weekly Reports, coronavirus-related studies published by the CDC.Â
« This is deeply concerning, » Gottlieb said in Tuesday’s « Squawk Box » interview. « You need to be able to accept that the material being put out by an organization, by an agency, represents the view of that agency. » He added that the administration officials could publish their views on the coronavirus but should do so under their signature and not the CDC’s.Â
« If it doesn’t represent the work of CDC, it shouldn’t have the CDC’s logo on it, » Gottlieb said. « I think that’s the most corrosiveÂ event of the last several weeksÂ â seeing information get put up on the CDC website that doesn’t necessarily represent the work of the CDC scientists or doesn’t represent the consensus of that agency. »Â
However, Gottlieb added that many scientists already believe the coronavirus could spread through the air under the right conditions, and that there was « nothing surprising » with the removed guidance.Â
« A virus that spreads predominantly through droplet transmission under certain circumstances is going to spread through aerosolization, » Gottlieb said. « I think people need to just assume that that’s the fact, most scientists at this point assume that. »Â
The World Health Organization has said Covid-19 primarily spreads through respiratory dropletsÂ that pass when an infected person coughs, sneezes or breathes. WHO officials said Monday that there are certain situationsÂ â people crowded into a small space without adequate ventilation for a long duration of time, for example â whereÂ aerosol-based transmission can occur. However, its advice on how to prevent the coronavirus’ spread hasn’t changed.Â
« It’s about knowing the risks, managing the frequency, intensity and duration of time you spend in the company of other individuals in crowded spaces, » Dr. Mike Ryan, executive director of the WHO’s health emergencies program, said during a press briefing.Â
