Some lesser - known ones might be 'Konosuba: God's Blessing on This Wonderful World!'. The main character is transported to a new world and has to deal with all sorts of crazy situations. It's not exactly reincarnation as a virus, but it has that sense of starting anew in a strange place. Also, 'Grimgar of Fantasy and Ash' where the characters find themselves in a new world and have to adapt, which is somewhat related to the general idea of the given light novel.
Well, I'm not sure if there are exact replicas, but 'Sword Art Online' has some reincarnation - like themes in the sense that the characters are kind of 'reborn' into a virtual world. And 'Log Horizon' is also a good one where the players are in a new world situation, much like in the 'reincarnated as a virus' concept, they have to figure out how to survive and thrive in this new place.
Another unique aspect could be the moral and ethical implications. Since viruses are often seen as harmful in our world, the story might explore how the reincarnated virus deals with this perception. Does it try to change its nature? Or does it have to fight against the world's natural defenses against it? These are the kinds of deep and thought - provoking ideas that could make this light novel stand out.
