USING THE SOUND OF A COUGH TO FIGHT A GLOBAL EPIDEMIC
The challenge & Our AI Solution
Identifying TB early is key, but traditional screening can be slow and miss cases, especially in resource-limited settings or when individuals don’t show obvious symptoms currently India accounts for 26-27% of the global TB burden.
CAT is an app that analyzes the sound of a person’s cough, along with self-reported symptoms, to quickly screen for presumptive pulmonary TB.
Developed with India’s Central TB Division, this AI tool works offline on smartphones, making advanced screening accessible anywhere.
