during the third trimester of the second stage pregnancy, both parents go into a pre-speciation puberty to prepare them for the needs of their novel child. facial pigmentation changes underneath the old skin which begins sloughing off like a mask. vocal organs and olfactory glands alter and sensitize respectively, to adapt for a new form of communication. for over a year after the first sheva outbreak in the united states, no second stage fetus was recorded to have been born alive. the new human species was highly sensitive to all varieties of herpes and could not be viably born to a mother who had ever been infected with any of the virus' many forms, including epstein-barr and the chickenpox, thus eliminating 95% of the female population. anesthetics and pitocin administered during childbirth were also lethal. so while many women would contract activated sheva that few would manage to give birth, making the transition from "homo sapiens sapiens" to the new human species very gradual.
