It seems pretty clear to me that Eko is either unknowingly a zombie already, or is at the very least some kind of mutant carrier for the virus:
- We see she's sick with a fever in Ch. 1 immediately before the zombie pandemic takes out the world (and sleeping for two whole weeks out of nowhere is suspicious on its own)
- She's able to casually stroll through the zombie-infested city without getting attacked at all; we see her literally walk right past a zombie on her way to school without either of them noticing each other, and she and Risa didn't appear to be moving with any sort of caution on their way to the theater either
- She's single-mindedly following her established pre-apocalypse desires: kill her bullies and be together with the girl who wanted to befriend her

With that in mind, it's entirely possible that Eko could have transmitted the virus to one of the group members, leading to their downfall.
