    The CDC has released a statement confirming that Zika virus, a mosquito-borne pathogen currently spreading throughout the Americas, causes microcephaly and other birth defects in children born to mothers who contract the virus during pregnancy:

    Here's the summary of the NEJM article cited:

    Yeah good point all sexual contact can resultant in exposer. But heterosexual transmission could be a way of transmitting the virus through fertilization directly into the ovum. I can see how that could cause the chromosome damage at the onset of pregnancy.

    The virus could adhere to the zygote directly during cell division and development causing the egg itself to become infected.

    I'll try to find the article, I think its mostly speculative at this early stage. Zika being linked directly to microcephaly. It would stand to reason that the transmission of the virus sexually during conception would be the optimal way to transmit the disease to the unborn child.

    This is the best article: its still speculative its known that its transmitted across the placenta, what's not known is if fetal infection can occur first transmitting it straight to the egg. But the article leaves room for that inference.
