Why Tuberculosis is still the most deadly infectious disease.

Attention, DNA detectives! We’ve got a rat on the loose – but don’t worry, not the snitching, double-agent kind. We’re talking about the whiskered, hyper-skilled, tiny agents who aren't snitching - they're sniffing out one of the world’s deadliest diseases: tuberculosis (TB).

Tuberculosis might sound old-timey, but it’s still the globe’s top infectious killer– growing tougher, more drug-resistant, and hitting hardest where access to care falls short. So for our Season 5 finale, host Dr. Kaylee Byers digs into TB’s fascinating backstory, and teams up with microbiologist Dr. Jennifer Guthrie to figure out why this ancient disease still has such a tight grip, and how genomics is helping track its every move. Along the way, Dr. Zolelwa Sifumba shares her story as a multidrug-resistant TB survivor, and how her treatment journey fuels her advocacy today.

Buckle up: this investigation has it all : science, politics, global inequities… and a squad of extraordinary rats.

Special thanks to APOPO for sending us field recordings and interviews from their HeroRAT training program.
