Aza shares with the reader that the human body is made up of about 50% bacteria; essentially, half of a person's cells aren't technically that person. Aza's OCD makes this knowledge unbearable for her and she's obsessed with keeping herself as clean and bacteria-free as possible. The way she conceptualizes bacteria as controlling, invasive, and malicious symbolize a literal split in Aza's identity: the bacteria provide Aza proof that her identity is not her own.
