Abigail was a nurse who was always first on the scene. She saw and calmly and confidently treated all sorts of trauma and she would always give 110% to the patients she saw.

A month prior to the virus that spread and zombified most men, and killed most women, Abigail was stuck by a needle while attending to a patient. The patient was a female police officer that Abigail had seen in passing several times through recent years dealing with different situations in the ER. The patient had some bizarre symptoms that had just come on a day prior, and a day after being stuck, Abigail came down with the same symptoms.

Evidently this illness was some early form of the virus which some how gave an immunity to both women, when the majority of the women died as the zombie plague spread.
