[In January 2020,
-
Christian Happi and Pardis Sabeti
presented an Audacious idea]
-
[Sentinel: An early warning system
to detect and track the next pandemic]
-
[Here's how it would work ...]
-
Christian Happi: Sentinel is a proactive
early warning system to preempt pandemics.
-
It is built on three major pillars.
-
Pardis Sabeti: The first pillar is Detect.
-
Christian and I have been studying
infectious diseases together
-
around the world for two decades.
-
We have been using genome sequencing.
-
Reading out the complete
genetic information of a microbe,
-
it allows us to identify viruses,
even those we've never seen before,
-
track them as they spread
-
and watch for new mutations.
-
And now with the powerful
gene-editing technology CRISPR,
-
we can use this genetic information
-
to rapidly design exquisitely sensitive
diagnostic tests for any microbe.
-
CH: One of these tools is called SHERLOCK.
-
It can be used to test known viruses
on simple paper strips.
-
It is very inexpensive,
-
and frontline health workers
can use SHERLOCK
-
to detect the most common
or the most threatening viruses
-
within an hour.
-
PS: The other tool is CARMEN.
-
It requires a lab, but it can test
for hundreds of viruses simultaneously.
-
So hospital lab staff
can test patient samples
-
for a broad range of viruses
-
within a day.
-
Our second pillar is Connect.
-
Connect everyone
and share this information
-
across the public health community.
-
In most outbreaks,
-
hospital staff share case information
through paper, Excel -- if at all.
-
This makes tracking an outbreak
through space and time
-
and coordinating a response
-
extremely difficult.
-
So we're developing a cloud-based system
and mobile applications
-
that connect community health workers,
-
clinicians, public health
teams -- everyone --
-
and allows them to upload data,
-
perform analysis, share insights
-
and coordinate a response and action plan
-
in real time.
-
CH: Our third pillar is Empower.
-
An outbreak surveillance
system can only succeed
-
if we empower frontline health workers
that are already out there
-
taking care of communities.
-
It requires a lot of training.
-
Pardis and I are very much aware of that.
-
We've spent the past 10 years
-
training hundreds of young
African scientists and clinicians.
-
Over the next five years, we will train
an additional 1,000 health workers
-
to use Sentinel detection tools
-
and empower them
to train their colleagues.
-
This way, we will improve
the original health care system
-
and integrate surveillance
into medical practice.
-
[Since presenting their Audacious
plan at TED, the world has changed ...]
-
Briar Goldberg: So here we are.
We're recording this.
-
It's April 7th, 2020,
-
and obviously, we are in the throes
of this crazy global pandemic
-
caused by this new coronavirus.
-
So you two have been working
together forever,
-
and you really came together
pretty aggressively
-
with the Ebola crisis back in 2014.
-
What does it feel like
from your perspective?
-
CH: Pretty much six years
after the Ebola outbreak,
-
we're really facing another crisis,
-
and we still pretty much, like,
we never learned from the previous crisis.
-
And that, really, for me,
is heartbreaking.
-
PS: I think that this pandemic
has shown us how unprepared we are
-
everywhere in the world.
-
Christian and our partners together
had diagnostics at our hospital sites
-
in Nigeria, Sierra Leone
and Senegal in early February.
-
Most states in the United States
didn't have it until far later.
-
It tells us that
we are all in this together,
-
and we are all very much behind the curve.
-
BG: So, this Sentinel system is amazing,
-
but I know that the question
that's on everybody's mind is:
-
How is that playing into the here and now?
-
PS: You know, we describe Sentinel
as a pandemic preemption system,
-
and here we are in a pandemic.
-
But what's great is that, actually,
the same tools you need
-
to preempt a pandemic
-
are the ones that you need
to respond to one.
-
And so all of the technologies
that we have laid out --
-
the point-of-care testing,
the multiplex testing,
-
the discovery and tracking
of the virus as it's changing,
-
and the overlay of the mobile
applications to dashboard --
-
are all critical.
-
CH: For us, it is a war.
-
We are basically committed
for 24 hours' turnaround time
-
in order to give results,
-
and that requires for us
to work around the clock nonstop.
-
So it's a pretty challenging moment.
-
We are away from family.
-
At least I have the privilege
to see family today,
-
and then I'm sure tomorrow
I'm heading back in the trenches.
-
In my lab, we sequenced
the first COVID-19 genome
-
on the African continent,
-
and that really was done within 48 hours.
-
This is revolutionary
coming from Africa
-
and then making this information
available for the global health community
-
to see what the virus
within Africa looks like.
-
I believe that with
technologies and knowledge
-
and then sharing information,
-
we can do better and then we can overcome.
-
PS: The whole idea of Sentinel
-
is that we all stand guard
over each other.
-
We all watch.
-
Each one of us is a sentinel.
-
Each one of us, being able to monitor
what is making us sick,
-
can share that with
the rest of our community.
-
And I think that is what
I profoundly want,
-
is for us to all stand guard
-
and watch over each other.
