How We’re Using Dogs to Sniff Out Malaria: James Logan (Transcript)

James Logan at TEDxLondon Talks


Malaria is still one of the biggest killers on the planet. Despite us making significant progress in the last 20 years, half the world’s population is still at risk from this disease.

In fact, every two minutes a child dies from Malaria. Our progress has undoubtedly stalled.

Now, we face many challenges when it comes to tackling Malaria. But one of the problems that we have is actually finding people who are infected with Malaria in the first place.

So for example, if people have some level of immunity to the disease, then they can develop an infection and become infectious and still pass it on, but not actually develop any symptoms. And that can be a big problem because how do you find those people — it’s like looking for a needle in a haystack.

Now, scientists have been trying to solve this problem for some years, but what I want to talk to you about today is that the solution to this problem may have been right under our noses this whole time.

That was a bit of a heavy start with lots of really important and serious statistics. So I want us all to just relax a little bit now, help me to relax a little bit as well.

So why don’t we all take a nice deep breath in. (Inhaling) Wow! And sigh.

Okay, I’m going to get blown away there. Okay, now I want you to do it again, but this time I want you to do it just through your nose, and I want you to really sense the environment around you.

And in fact, I want you to really smell the person who is sitting next to you, even if you don’t know them. I don’t care! Lean in. Get your nose right into their armpit. Stop being so British about it. Get your nose into the armpit, have a good old sniff. See what you can smell.
