There are several issues involved:
1) The efficient detection of the Zika virus in pregnant women, only detectable for a short period.
2) The positive relation between Zika and microcephalia, something not yet 100% established although suspected.
3) And all of the public and religious policies.
Many women do not even know that they have had the virus, and others are outside of the normal health system when they
learn that they are pregnant. It is a major issue right now, and there are not shortcuts to any solution.
It will take at least 6 months to produce a vaccine--if one works.
They do not have a widely available technology for detecting the virus, especially in the most vulnerable areas it occurs.
Save arguments. Not worth the angst.
Over 4000 cases in Brazil...with microcephalia up about 10 times normal in some areas...
Not a happy picture.
