It's got to be the latter. HIV/AIDS in the West is essentially "cured" not a death sentence anymore. But even in the West we're cooking up nasty TB strains in our homeless/street population, as well as importing them from other countries.
I saw a documentary a couple years back that pointed to Russian prisons as one of the worst. People get treatment for TB in prison (that they contracted in Prison), but can be released and in New York the next day still with active TB that is now partially drug resistant.
And TB is actually airborne, meaning that spores can float around in the air for 3 or 4 hours after someone coughs.
