Zika virus 'spreading explosively,' WHO leader says

Zika virus 'spreading explosively,' WHO leader says:

The WHO is worried.. As are pregnant women.. And millions could be affected within the coming months.. 80% of people who get it don’t know they had it.. The problem is babies in the womb.. This from CNN:

Some 80% of those infected with the Zika virus never know they have it. But there are major worries about the dangers pregnant women and their babies face.

Chan said that, where the virus has arrived, there’s been a corresponding “steep increase in the birth of babies with abnormally small heads and in cases of Guillain-Barre syndrome.” Having small heads can cause severe developmental issues and sometimes death. Guillain-Barre is a rare autoimmune disorder that can lead to life-threatening paralysis.
