Perfecting Ebola Contact Tracing — Factpod #13

• 0:05 - 0:06
I am professor Hans Rosling
• 0:06 - 0:09
I'm am participating in the fight against Ebola
• 0:09 - 0:11
here in Liberia.
• 0:11 - 0:15
In this country the number of new cases per day has come down
• 0:15 - 0:19
from almost 100 in the end of september
• 0:19 - 0:21
to now in the beginning in December
• 0:21 - 0:22
around 10 per day.
• 0:22 - 0:24
But that is still very dangerous!
• 0:25 - 0:30
Because the only safe and stable level for Ebola is zero cases per day.
• 0:30 - 0:33
So we say Ebola must go all the way down to zero.
• 0:33 - 0:35
We must stop transmission among humans.
• 0:36 - 0:38
But that is difficult now at the low level
• 0:38 - 0:42
because Ebola is hiding in between the other infectious diseases
• 0:42 - 0:46
So we have to be like detectives and hunt the virus
• 0:46 - 0:50
and we do that using a method called "contact tracing".
• 0:50 - 0:51
I will show you how it works.
• 0:52 - 0:57
Imagine that this is a patient that is very sick with Ebola.
• 0:57 - 1:04
It's a contagious disease and everyone that has been in contact with this patient may be infected.
• 1:04 - 1:07
So what we need to do are two things:
• 1:07 - 1:11
we need to take the patients to an Ebola Treatment Center and isolate them,
• 1:11 - 1:16
and then we have to list all the contacts.
• 1:16 - 1:19
We have to make a list with everyone that was in contact
• 1:19 - 1:24
with this patient during the days that he/she was sick.
• 1:24 - 1:27
Then we start what we call the 'contact tracing'.
• 1:27 - 1:33
In the next 21 days
• 1:34 - 1:37
• 1:37 - 1:42
and we have to follow them everyday, check the temperature and ask them how they feel
• 1:42 - 1:45
and if one of them is infected,
• 1:45 - 1:47
let's say that this one is infected
• 1:47 - 1:48
and this one is infected
• 1:48 - 1:51
we don't know, there is no test we can use.
• 1:51 - 1:53
So we just have to follow them.
• 1:53 - 1:58
Now those who are not infected, we follow them for 21 days and we find nothing
• 1:58 - 2:00
we follow this one, we find nothing
• 2:00 - 2:01
same here
• 2:01 - 2:02
same here
• 2:03 - 2:06
But this one that has the virus in the body
• 2:07 - 2:12
after 10 or 15 days, they get fever, headache, diarrhea
• 2:12 - 2:15
and then very fast we isolate them.
• 2:15 - 2:19
So when they develop full blown Ebola here
• 2:19 - 2:23
they are very contagious, they are already in the Treatment Center
• 2:23 - 2:24
and they are isolated.
• 2:24 - 2:27
Now this one here...
• 2:27 - 2:30
May not have confidence in our system
• 2:30 - 2:31
they are scared and they decide...
• 2:32 - 2:35
"no, I get a little fever today, hope it's malaria"
• 2:35 - 2:37
and they move away somewhere else
• 2:37 - 2:39
they avoid our contact tracers.
• 2:39 - 2:41
That's very dangerous!
• 2:41 - 2:45
Because then they would get Ebola outside our control
• 2:45 - 2:47
and they may infect other persons.
• 2:48 - 2:50
And we may also have missed one person down here
• 2:50 - 2:53
Let's say this is the brother to the case
• 2:53 - 2:57
and he took a bicycle and went to relatives' to live there.
• 2:57 - 3:01
If he was infected, we won't know it.
• 3:01 - 3:04
He will develop Ebola here and infect others.
• 3:05 - 3:10
So we need a perfect contact tracing system,
• 3:10 - 3:14
and perfect means that everyone has to be listed.
• 3:14 - 3:17
So that when they develop the disease
• 3:17 - 3:19
we can isolate them immediately.
• 3:19 - 3:25
And those who are scared and don't trust that it's the best to wait for the contact tracer
• 3:25 - 3:28
we have to convince them and have to be very kind
• 3:28 - 3:33
so that they would like to be included in our system
• 3:33 - 3:34
and we can isolate them like that.
• 3:35 - 3:37
Now the challenge today in Liberia is that
• 3:37 - 3:40
we have six thousand contacts we are following.
• 3:40 - 3:42
and they live throughout the country
• 3:42 - 3:44
most of them here in Monrovia.
• 3:46 - 3:48
And it's far from a perfect system.
• 3:49 - 3:52
We have a leakage of patients who are not in the system
• 3:52 - 3:53
like this one
• 3:54 - 3:56
and those who we loose during the control.
• 3:56 - 3:58
But they're getting better and better.
• 3:58 - 3:59
And we need more resources
• 3:59 - 4:02
today we don't need more Ebola Treatment Units
• 4:03 - 4:05
we need more international support for
• 4:05 - 4:06
this contact tracing.
• 4:06 - 4:10
And we need people who come and stay for several months
• 4:10 - 4:14
then we can find all these contacts
• 4:14 - 4:16
and we can follow them perfectly
• 4:17 - 4:21
So somewhere in the next year
• 4:21 - 4:24
when we have made this better and better
• 4:24 - 4:27
then we may end Ebola transmission completely.
• 4:27 - 4:30
And then it also has to be done in the neighbouring countries.
• 4:30 - 4:33
That is possible, but it requires lots of resources
• 4:33 - 4:35
and lots of endurance
• 4:35 - 4:36
that we don't give up
• 4:36 - 4:38
because we have only one objective:
• 4:38 - 4:42
Ebola must go! Go all the way down to zero.
