If my main and only sim in the household, who im going through the story with, is infected; can I still play through the whole story without needing the help of a another sim to fix her and/or also so...
If your sim is infected, they can make friends with Mother, and some really nice things will happen between the infected sim and Mother, I won't say anymore so as not to really spoil things. I have a sim who purposely got herself infected, and now she has something....well I won't say, let you find this out. :)
