It goes completely against the design intent of the game.

The devs themselves wrote a whole thing about this in regards to people asking about various things like an antidote and some way to “win” (escape the quarantine zone, military comes in and saves survivors, etc.) and you should check it out because it’s much better worded than what I can write paraphrasing it from memory.

Basically, the game is based on old-school zombie horror movies where death is just one bite away and an inevitability, whether it comes tragically or stupidly from you getting overconfident. It’s why the game starts with that cutscene saying that there were no survivors and this is the story of how you died. Being able to cure the infection takes away a major part of the pressure that the game places on you, and I think it goes against the narrative of the game? I thought the lore was that outside the quarantine zone, the rest of the world had died to the infection.
