On average, Apopo rats find an additional 40% of TB cases on top of those discovered by clinics. Since they started work 10 years ago, they have screened nearly half a million samples and detected more than 12,200 missed cases. They can get through 100 samples in 10 to 20 minutes: a human with a microscope takes four days to test the same number.
