Why is tuberculosis so serious?

(Location: California, USA)

Every now and then, the local news & local government announces that a TB case has been identified in the community, and it gives a list of possible locations & times at which people maybe have been exposed to it.

Example: Active TB case identified at X Gym. Possible locations include ABC train route, DEF school, XYZ grocery store…

Why is contact tracing for TB so much more serious than the flu or common cold?

Tuberculosis (old timey name “the consumption”, if you read victorian/colonial setting books there’s probably at least one background character dying/dead from it in your protagonist’s family or social circle) gradually destroys the lungs – as in, “eats actual caverns into your lung tissue until you have none left” – until you choke to death. With antibiotics it is no longer a death sentence, but if you get it there is still approximately as much chance of dying from it as from a single round of russian roulette.
