WaPo | The Centers for Disease Control and Prevention on Monday removed language from its website that said the novel coronavirus spreads via airborne transmission, the latest example of the agency backtracking from its own guidance.
“Unfortunately
an early draft of a revision went up without any technical review,”
said Jay Butler, the CDC’s deputy director for infectious diseases. “We
are returning to the earlier version and revisiting that process. It was
a failure of process at CDC.”
Evidence
that the virus floats in the air has mounted for months, with an
increasingly loud chorus of aerosol biologists pointing to
superspreading events in choirs, buses, bars and other poorly ventilated
spaces. They cheered when the CDC seemed to join them in agreeing the
coronavirus can be airborne.
Experts
who reviewed the CDC’s Friday post had said the language change had the
power to shift policy and drive a major rethinking on the need to better
ventilate indoor air.
Jose-Luis
Jimenez, a chemistry professor at the University of Colorado at Boulder
who studies how aerosols spread the virus, told The Washington Post
before the CDC reversed its guidance “this is a good thing, if we can
reduce transmission because more people understand how it is spreading
and know what to do to stop it.”
Although CDC officials maintained Friday’s post was a mistake,
Democratic lawmakers were incredulous. Rep. Raja Krishnamoorthi (D-Ill.)
tweeted Monday afternoon that he would investigate why the language to
airborne transmission had been scrubbed.
