• So far, only humans are affected--a non-mutated cat was specifically mentioned as getting away from a Behemoth.
  • The foragers who went near what they thought was ground zero were said to get nauseous. Radiation? Radio Waves? Microwaves?
  • There were strange lifeforms near ground zero, but we don't know what that means. Could be mutations, could be from other dimensions (like Stephen King's The Fog) or planets (like War Of The Worlds).
  • It's only spread by direct contact between infected blood and cuts/openings in the skin.
  • Infects very quickly
  • It results in different types of mutations in humans


Another theory which would be interesting is if the infection was spread in an inert state in tattoo ink and activated by a certain frequency.
