There a LOT I don’t know about Zika. What’s the nature of “genital malformations”? Do those malformations preclude reproduction? can the virus also be spread as any bloodborne virus is, or are mosquitos or non-human hosts the carrier? At what stages of pregnancy are the dangers to the unborn relevant, prevalent? How long does the virus live in the host (I don’t know the jargon to describe its “life cycle”)? Or in paranoid terms- How does this virus differ from one that was specifically designed to interrupt reproduction of people living in the tropics, subtropics???
