This graph shows the number[br]of new cases of Ebola in Liberia,

0:00:07.599,0:00:13.000
from 15th of August all the way up[br]to the first week of December.

0:00:13.000,0:00:18.079
And look: in mid-august,[br]it was about 10 cases per day,

0:00:18.079,0:00:22.359
then started the catastrophe:[br]it increased like this,

0:00:22.359,0:00:28.600
and continued up to almost 70[br]registered cases in the end of September.

0:00:28.600,0:00:31.879
But there were also many missed[br]cases, so it may have reached

0:00:31.879,0:00:34.560
all the way up to[br]100 new cases per day.

0:00:34.560,0:00:37.880
But then we are very sure[br]that it came down like this,

0:00:37.880,0:00:41.640
during October, because the measures[br]taken in this country

0:00:41.640,0:00:43.920
were the right ones in the catastrophe:

0:00:43.920,0:00:48.280
cases were insulated,[br]population was informed,

0:00:48.280,0:00:53.200
they changed their behaviour,[br]the dead bodies were taken care of

0:00:53.200,0:00:57.759
with safety barriers:[br]everything went relatively well,

0:00:57.759,0:01:01.280
and we are down, now, here,[br]at ten per day.

0:01:01.280,0:01:07.040
But remember: the epidemic in Nigeria[br]never reached one case per day!

0:01:07.040,0:01:12.100
Nigeria didn't come up here,[br]so it's more then ten, twenty times

0:01:12.100,0:01:17.120
more difficult here today in Liberia,[br]then Nigeria ever had.

0:01:17.120,0:01:21.120
It means, we have now to make functioning

0:01:21.120,0:01:24.840
an almost perfect contact tracing system,

0:01:24.840,0:01:29.079
so that we can insulate[br]all new cases, very very rapidly,

0:01:29.079,0:01:30.959
before they transmit to others.

0:01:30.959,0:01:34.760
And that's what we're building now:[br]but it will take a lot of resources,

0:01:36.760,0:01:40.300
because we may go several[br]months into the next year,

0:01:39.400,0:01:42.840
because the objective is very clear:

0:01:42.840,0:01:46.079
we have to bring[br]Ebola transmission to zero!

0:01:46.079,0:01:49.400
The only safe and stable level[br]of Ebola is zero cases!
