[@ianzerep] Biting a zombie would probably cause an infection if the zombie blood is swallowed. Slicing and stabbing moves do draw blood, but unless the infected person/pokemon's biological material(I'm sure there's a better word, I just can't think of it at the moment) gets into the bloodstream, the biting attacks are what you'll have to worry about most. Also, I'm thinking of making steel and ghost types immune to the virus.
