Despite global fears of pregnant women delivering babies with microcephaly if they contract the Zika virus [1], one new mother just gave birth to a "clinically healthy" baby.

According to Mexico's health ministry, the mother became infected with the mosquito-borne disease while pregnant with her baby boy — but it doesn't appear that the virus led to any potentially debilitating birth defects. The new mom, who is only one of six known Mexican mothers-to-be to be infected with the virus during pregnancy, delivered her son in Tuxtla Gutierrez [2], Mexico.

Although the Zika virus has been connected to microcephaly, this little boy was born with an average-size head (a clear sign that he doesn't have this devastating birth defect) and weighed in at 6 pounds. The other five women are all being treated with specialized care throughout their pregnancies, and two have even made it past the 28-week mark without any signs that their unborn babies are not developing properly.

More research is being done to try and understand the link between the Zika virus and microcephaly — including whether the mother's age, the trimester in which she contracts the disease, or genetics play a role in a newborn's chances of being born with birth defects. But for now, this is a welcome update in what has up until now been an increasingly frightening epidemic.
