A small percentage of women were at risk from reported travel to Zika virus-affected areas, with those traveling from heavily affected areas most at risk for infection, a recent study found. These results were from a large prenatal Zika screening program at a single center health care system from March 14 through October 1, 2016, that included 14,161 pregnant women (predominantly Hispanic) screened for travel to a Zika-affected country. Researchers found:

• 610 (4.3%) women reported travel; test results were available in 547.
• Evidence of possible Zika virus infection was found in 29 (5.3%) women.
• 4% were at risk from reported travel with only 2 in 1,000 infected.
• There was no significant difference in obstetric or neonatal morbidities among women with or without evidence of possible Zika virus infection.
• Similarly, there was no difference in mean head circumference of infants born to women with positive vs negative Zika virus testing.
