A male and a female still need to engage in sex to make a baby, but it is seen as a dangerous, nasty chore.

The novel's point of departure is a murder: this seemingly idyllic world, in fact, has serious social problems. Theoretical basis From the perspective of epidemiology, the basic goal behind social distancing is to decrease the effective reproduction number, or , which in the absence of social distancing would equate to the basic reproduction number, i.e.
