From another article: the person in question might be mentally disabled or otherwise incapable of understanding their infection[1]. It's otherwise hard to imagine why someone would walk around with an active (and not latent) tuberculosis infection for over a year.

Incarcerating someone is not an ideal outcome, but an understandable one in the presence of other pressures (like the absence of adequate mental health facilities). It would be interesting to see more reporting on those pressures.
