well, disease in general hasnt been mentioned by the developers as even being in the game (at least, nothing that i recall, or have seen elsewhere on the discourse)…
the health care/disease thread is just a place for discussion on the potential inclusion…
edit: we do have the potential for zombies though, so… there’s that… 
Can we raise the dead?
“Yes …it has to make it in, we don’t know how, but it has to make it in. There will be some way, you might not like it. Maybe this is how the zombie apocalypse starts … maybe the penalty for losing someone is that you have to ‘res’ them, and ‘ressing’ them too often could turn them into a zombie … zombie apocalypse should be a way to lose the game”
