I would switch the main catalyst for transformation to something other than zombie bites, with zombies being a likely outcome of that catalyst and their bites only able to create other zombies.
As an example, somebody invents a Horror Movie Trope Gun. You get shot with it and you turn into a random thing from a horror movie, which tends to be a zombie because there have been millions of zombies shown on screen. A few lucky people get something better from the random transformation. (Just replace Horror Movie Trope Gun with something that doesn't sound stupid.)
