Well yes, but the difference here is that those that are "infected" are done so by supernatural creatures, possibly following the whole "bitten by one of them - become one of them" monster trope, as seen with zombies, therianthropes (collective term for were-animals in general), and vampires. However, in MC's case, I guess it is kinda like that - and I agree with you, this has to have been one of my favorite games I found on here (I've always had a bit of a shapeshifter power fantasy - mainly cause its most likely one of the most versatile of powers and depending on the variant, virtually limitless in potential)
