CDC Director:
'Very Aggressive' Contact Tracing Needed For U.S. To Return To Normal

Heard on Morning Edition
Robert Redfield, director of the Centers for Disease Control and
Prevention, spoke with NPR on Thursday, saying that his agency is working on a
plan to safely reopen the United States.
It's the question on
everyone's minds: What will it take for us to come out of this period of
extreme social distancing and return to some semblance of normal life?
It turns out that the
Centers for Disease Control and Prevention has been working on a plan to allow
the U.S. to safely begin to scale back those policies. CDC Director Robert
Redfield spoke with NPR on Thursday, saying that the plan relies on not only
ramped-up testing but "very aggressive" contact tracing of those who
do test positive for the coronavirus, and a major scale-up of personnel to do
the necessary work.
Contact tracing is the process of finding and reaching out to
the contacts of someone who tests positive for an infectious pathogen. Those
contacts are then quarantined or monitored, and if any of them are also
positive, the process is repeated with their contacts, and on and on, until the
chain of transmission is halted. It's a labor-intensive, time-consuming practice that for
decades has been a fundamental public health tool for containing infectious
diseases.
Contact tracing was used in Seattle and parts of California
early on in their coronavirus outbreaks, but as community spread took hold,
many cities and states switched to a "mitigation" approach, like closing schools
and other social distancing measures. Now, much of the country is on lockdown (with a few exceptions).
To be ready for those
measures to ease up, Redfield said his agency is ramping up America's capacity
to do more contact tracing. "We are going to need a substantial expansion
of public health fieldworkers," he said. This, along with ample testing,
is what will be needed "to make sure that when we open up, we open up for
good."
The first step will be to expand testing, especially testing
that provides rapid results, so people can get diagnosed quickly. Redfield's
agency has received a lot of criticism for failing to quickly
deliver working tests to public health labs. (Redfield defended
the CDC on this point, saying that when problems with the initial test were
discovered, "we figured it out and corrected it. Somebody might say that's
botched — I don't think that's botched.") Redfield said that now, testing
capacity is increasing daily and that he's encouraged to see that point-of-care
tests that give results within minutes are starting to enter the market.
Next, Redfield said,
America will need to scale up capacity for tracing the contacts of those who
test positive. "It is going to be critical," he said. "We can't
afford to have multiple community outbreaks that can spiral up into sustained
community transmission — so it is going to be very aggressive, what I call
'block and tackle,' 'block and tackle.' "
Given how laborious
contact tracing is, that means bringing on a lot more people to do that work.
Since state and local public health departments aren't likely to have the staff
to do this, Redfield suggested, the federal government will need to help. "We
have over 600 people in the field right now from CDC in all the states trying
to help with this response, but we are going to have to substantially amplify
that," he said.
For context, in February the World Health Organization reported that in Wuhan,
China, to contain that outbreak, "1800 teams of epidemiologists, with a
minimum of 5 people/team, are tracing tens of thousands of contacts a
day." And that's just in a single city.
Redfield said it would
be "premature" for him to specify how exactly the CDC will do this
and how much staffing it plans to put in place. But he said an announcement
will come in the near future. "Obviously, if we're going to try to get
this nation back to work shortly after the end of this month, we're far along
in those planning processes as we speak," he said.
Other places — such as South Korea, Singapore and Hong Kong — that have been praised for success in
"flattening the curve" of coronavirus infections have used methods
for contact tracing that might not fly in the U.S. because of privacy concerns.
For instance, South Korea uses a variety of tools such as surveillance
cameras, cellphone data and credit card transactions of suspected cases to help
map transmission.
Redfield left the door
open for contact tracing in the U.S. to employ cellphone data. "People are
looking at all the different modern technology that could be brought to bear to
make contact tracing more efficient and effective," he said. "Are
there more tech-savvy ways to be more comprehensive in contact tracing?
Currently these things are under aggressive evaluation."
He added that
ultimately it will be up to state and local public health departments to
determine how to do contact tracing. The CDC is there, Redfield said, to offer
technical assistance and to "augment personnel substantially."
The Kaiser Family Foundation recently noted that state and local health
departments are already stretched thin and that "only the federal
government could truly bring order and achieve a national, coordinated effort
on the scale (and expense) necessary" for contact tracing to be effective
in the United States.
Redfield acknowledged
the problem of public health neglect. "The reality is, for decades we've under invested in public health," he said. "So this is a time for us
to reinvest heavily — get over prepared."
Despite the enormous
tasks ahead, Redfield sounded optimistic in his conversation with NPR, saying
that he thinks we're nearing the peak of the current outbreak in the U.S. and
should see a decline in cases over the next few weeks.
"I think we've
seen an enormous benefit of the social distancing guidelines, and this is
really a credit to the American people," he said.
But he emphasized that
Americans can't let up yet. It's clear "this virus is extremely
infectious," he said, and moves fast. So until an effective vaccine is
found and made available, our best hope for containing its spread is to fight
back potential new outbreaks with public health workers on the ground.
