A new study has shown that pregnant monkeys stay infected with Zika longer indicating an infection loop between mom and fetus. Zika virus infection confers protection against future infection in monkeys but lingers in the body of pregnant animals for prolonged periods of time according to the research.The team led by University of Wisconsin-Madison pathology professor David O'Connor infected eight rhesus macaque monkeys with the Zika virus strain responsible for the current outbreak in the Americas. Non-pregnant monkeys cleared the virus from their blood approximately 10 days after infection which is similar to what is seen in humans with Zika
