Just spitballing here, but with Lycanthropia, we might be dealing with a highly unstable disease. Blutbaden that have it can't control when it manifests, and there has never been a cure found for it. Perhaps there have been very few documented cases of a human getting affected by the disease because most humans that have come into contact with a Lycanthrope haven't lived to tell the tale of their encounter.

Because of that, and the fact that Blutbaden families killed their own who showed signs of having it, the disease might not be as well-understood as it could be. Think Peter Parker turning into Spiderman – the radioactive spider's DNA was unstable and started affecting Peter's DNA immediately. That's sort of why I'm worried that Wu may lose his human form entirely if the disease keeps progressing – it is showing the same unstable qualities in that Wu is unable to control the transformations and onset of symptoms, and the disease is starting to control him, rather than the other way around.
