Dawn Dudley, scientist at the University of Wisconsin-Madison’s Department of Pathology and Laboratory Medicine and lead author on the study, said the problem with studies of Zika in humans is that they rely on symptomatic infections.

“Women get enrolled in the studies because they have Zika symptoms, but we know that up to half of people who have Zika don’t show any symptoms at all. So, the pregnancy studies are probably missing half of the people who have Zika,” she said. 

Lark Coffey, an arbovirologist at University of California, Davis and one of the study co-authors, said that women suffering miscarriages in areas where the Zika virus is prevalent may not realise why they are losing their babies.
