Hello, I’m Thomas Locke and this is Five Minutes, the podcast that brings you closer to the people fighting malaria.

The world’s access to mobile phones is increasing. Quartz Africa predicts that one billion people in Sub-Saharan Africa will have one by 2023. Fatou Secka, a student at Dalhousie University in Canada, is using this to revolutionise malaria diagnosis.

Using a 3D-printed lens clip that attaches the back of a smartphone camera, she hopes to detect the presence of malaria parasites in a blood sample - a useful tool in rural communities, where access to specialist equipment is limited.
