You're right that "retribution" is part of the deal when a person goes to prison. However, people are sent "as punishment", not "for punishment". 

Furthermore, all courts across America has acknowledged that prisoners do possess some constitutional rights, such as the right to be free from cruel & unusual punishment or the wanton & unnecessary infliction of pain.

As my own case before the United States Supreme Court has enunciated in 1995, courts will only accept those cases where the prisoner is subjected to the atypical & unnecessary infliction of pain. Everything else is a consequence of being incarcerated.

For example, when a prisoner ends up in solitary confinement, even if prison official violated the rules to get him there, that's just incidental to what one can expect for coming to prison.

With the atypical & significant hardship of being sent to a prison that is in a known zone for "valley fever", that is not typical & wholly avoidable. Thus, a civil action is next.
