The TEDxLondon talk delivered by Professor James Logan (Head of the Department of Disease Control at the London School of Hygiene & Tropical Medicine and Director of ARCTEC) in May 2019, on innovative methods for detecting and controlling diseases, has officially been made a TED Talk.

Professor Logan’s fascinating TEDxLondon talk, which included a live demonstration from a malaria-sniffing dog, was reviewed by the TED team and chosen to be uploaded onto the website to provide even wider coverage globally.

The insightful talk focused on research (co-led by ARCTEC) into how the sense of smell of insects and other animals can be used to develop novel methods to detect and control diseases.

Professor Logan explained that mosquitoes can actually detect the smell of malaria-infected humans, and find it significantly more attractive than uninfected human odour.

He concluded his talk with a look towards future possibilities – where novel tools, such as a smartwatch, could be developed to detect key “odour signatures” in humans when they are infected with malaria, based on the chemicals detected by dogs and other animals. And the likelihood is, this could be done for many other diseases too.
