Infectia (Josephine)

The woman who called herself Infectia learned a great deal about genetics from her father, a geneticist based in a Manhattan brownstone. As a result she was better able to comprehend the nature of her superhuman power to perceive and alter the genetic structure of other living beings. Upon her father's death, Infectia inherited the brownstone, the laboratory within it, and a fortune, and thereupon dropped out of high school.
