Low rates of confirmed maternal Zika virus infection were observed in women with potential Zika virus exposure; however, concern persisted among both patients and physicians regarding possible perinatal Zika virus infection. The longitudinal observational study from January to August 2016 from a single perinatal referral center included patients who traveled to or had sexual contact with a person who traveled to a region with documented local Zika virus transmission. Researchers found:

• 185 pregnant women with potential Zika virus were evaluated.
• 123 (67%) patients reported insect bites and 19 (10%) patients reported symptoms.
• 5 (3%) patients had prenatal ultrasound findings suggestive of possible fetal Zika virus infection; however, all tests were negative.
• Of the 153 Zika virus screening tests ordered, 8 (5%) immunoglobulin M results returned positive or equivocal with only 1 positive through confirmatory testing.
• Overall, 1 of 185 (0.5%) of all those consulted and 1 of 153 (0.7%) of those tested had a confirmed Zika virus infection with no confirmed fetal or neonatal infections.
