Can dogs sniff out malaria?

Malaria continues to threaten half the world’s population, with a child dying every two minutes. Detecting symptomless carriers has stalled progress in fighting the disease, but research shows malaria changes body odor, making infected people more attractive to mosquitoes. Trained dogs can sniff out these subtle scent changes, correctly identifying malaria in humans by smelling worn socks. This breakthrough opens the door to new, non-invasive ways to diagnose and control malaria using the power of nature.
