Noted: At the University of Wisconsin, virologist Dave O’Connor has been infecting macaques with Zika and carefully tracking the virus’ progress through time and tissues. During the pregnancies, his team repeatedly samples blood and amniotic fluid to determine how quickly the virus can infect a fetus. They take fetal MRIs to make measurements on how the baby macaque is growing. And once the pregnancy is complete, they analyze more than 60 different fetal tissues for little bits of Zika DNA and virus-induced damage.
