I can't remember. Are we allowed to put on a zombie skin to use the medicine for achievement? Or do we have to wait until it's an active strain? Or wait until survival?

I would definitely recommend not being infected when you use the cure, as it gives you a temporary overlay, and it'll reset your infection. (Found that out the hard way OTL) I'm not certain if they work outside of Survival, but I just got the Amoricide one a minute ago.

. Thank you
