[CNN is reporting](http://www.cnn.com/2016/02/01/health/zika-virus-public-health-emergency/index.html) that there is a potentially serious outbreak of this "*Zika virus*."

From all the [blogs and articles](https://www.romper.com/p/can-the-zika-virus-harm-toddlers-parents-should-get-their-children-tested-4739) out there on Zika, it is obvious that this virus is a serious threat to pregnant mothers and even newborn babies.

**What is not apparent in all this literature is: at what age is Zika no longer a threat for microcephaly in infants?** What's the cutoff?

I have a 10-month old and a 3-year old - is there cause for concerns outside of the normal viral symptoms or are they both developed enough to be "in the clear"?

If you can find literature to support your claims that's definitely even more reassuring!
