This is the short edition of More or Less, first broadcast on the BBC World Service.
Hello, this is More or Less on the BBC World Service and I'm Tim Harford. This week I was fortunate enough to speak to Hans Rosling. Hans is Professor of International Health at the Karolinska Institute in Sweden. He's also the co-founder and chairman of the Gapminder Foundation, which tries to make sense of the world's data. A couple of weeks ago, Hans flew to Liberia to join the fight against Ebola. I started by asking him what the numbers are currently telling us about Ebola in Liberia.
It's very clear that we are now in a second phase. Ebola in Liberia started coming over the border into Lofa County. Then it moved down during the summer and hit the capital, Monrovia, really badly in August and September. But now the numbers in the capital is down. But it's down from 75 a day down to around 25 a day or 20 a day. But now it has stopped. It is no longer falling. It is at an intermediate level. And over the last, let's say, seven, eight days, we record exactly the same number of newly infected people per day. So this is not a simplistic epidemic that goes up and then goes down and disappears. But it's all over the country. All of the 15 counties have had cases over the last weeks. And this means that we are fighting a low-intensity epidemic or endemic disease, as we used to call them, because it's going on with almost the same amount of people in countries
every week, but it flares up in one of the counties and then it's controlled there and then it jumps up at another place. This will take time to get rid of.
Just talk me through, please, this slightly technical term, the reproductive number. And I understand that the reproductive number has come down to one. Is that true? And what does it mean?
When it was at its peak, it was almost two. That means one infected person on average infected two others. That doesn't sound so dangerous. But since the period of transmission from one getting infected to to them getting sick and then infecting others, that's about three weeks. So it meant that the disease doubled in one month. And then it goes from 1, 2, 4, 8, 16, 32, 64, 128. That is the danger with this doubling in each passage of the virus through humans. Now, on average, one person infects one other. Of course, there are like five, ten cases that doesn't infect anyone because there's such a lot of precaution taken by people and the health service. But then every now and then there is one remote funeral and then five to six get infected.
So we see these clusters of outbreak and the task is to catch them as early as possible before neighbors have got infected. So we really need to have a good assistance for people. People understand this themselves. So in the village, when one family is infected, they would make a ring around that house in the ground and say, you don't go over this line. We don't step over the line. Here's the water. Here's the food you need.
What are the current Ebola case trends in Liberia and where did the outbreak move?
People on themselves understand what quarantine is. So a lot of this success in the first phase was won by the population themselves. And second phase, that's more scary because it will be a case here and a case there. Just yesterday, we had two who came back from a funeral back in their home village in another county, you know. And it turned out it was Ebola, but it had been an old person who died in a way which you would thought was this way that old people pass away. So it's more difficult to stop it now when it's at the low level than when it was at the peak.
How has the epidemic shifted into a 'second phase' and what does that mean for case numbers?
To take it from the peak down to low, that was easier than take it from low to nothing.
What impact is this having on the healthcare systems? And what's it doing to the hospitals, to the clinics?
Nurses in this country, doctors, medical assistants, they have to be very careful treating patients. But what they did when the international community was late in providing additional Ebola treatment centers, the medicines on frontier were here, they were not enough. Then the doctors from here started their own treatment center, WHO together with
