Once his experiments went out of control, the Jonas virus became the inception of the zombie apocalypse.
However, the virus would soon mutate and lead to a new class of zombies, the hambies.

Shortly after her encounter with Gwi-nam, Nam-ra started showing signs of infection but never fully transformed.
