There is a large fraction of the country that regards termination of pregnancy as literal child murder. Severe microcephaly is as good a reason to terminate a 'viable' pregnancy as can be found, with care for a microcephalic child costing far greater wealth than the average family has in their future; Most of the women not being identified will choose to abort.

"Abortion is murder" is something we've been deadened to through repetition, but the literal proclamation of abortion to be "murder", and "murder" to be murder, ethically requires extreme measures to fight it, to the believer. It is only through utter cowardice or lack of true belief that we manage to operate abortion clinics with a rate of violent assault in the last few decades cumulative of around 10%. These people are potentially dangerous, but within a family are also likely to do things like shunning/disowning relatives or seeking a divorce if this info becomes public.

I am not aware of any difference in how privacy is handled between the sexes (nor should there be).

Can you elaborate on where you see the difference in how privacy is handled?
