The virus would likely be handled in decontamination - Newt would be given an injection during the process (via a spray style device similar to a hypospray from Star Trek) and told by a pre-recorded announcement that he has a communicable disease which has been rendered inert (non-contagious) by the treatment. He would also be told he needs to report to the MedBay for this treatment on a regular basis to maintain inert viral status and if he misses his treatments he will be neutralized as a threat.

Depending on what stage of the disease he is at when you choose a canonpoint, it can either be prophylactic treatment given very simply during his decontamination process, or for more advanced stages where he was showing more physical signs, he could be held in a medical containment room and given treatment to reverse the effects on his body before being released with the same warning.
