Zika could be more dangerous to unborn babies because test on pregnant monkeys infected with the virus found that every single fetus had picked up some trace of Zika.
The research team infected four pregnant rhesus macaque monkeys at the Wisconsin National Primate Research Center with a Zika virus and
discovered that the virus was present in each monkey’s fetus.
The research group also found damage from Zika in every part of the interface between mother and fetus – the placenta, amniotic fluid in the womb and the lining of uterus.
Three of the baby monkeys were born with small heads, but not as small as it would need to be to meet the human standard for diagnosing microcephaly.
