Patterns in Zika Virus Testing and Infection, by Report of Symptoms and Pregnancy Status
- Updated: 28 January 2019
During January 3–March 5, 2016, Zika virus testing was performed in the United States for 4,534 people who traveled to or moved from areas with active Zika virus transmission; 3,335 (73.6%) were pregnant women. Among 1,541 people who received testing and reported symptoms, 182 (11.8%) had confirmed Zika virus infection. Only seven asymptomatic pregnant women (0.3%) had confirmed Zika virus infection. These data suggest that in the current U.S. setting, the likelihood of Zika virus infection among asymptomatic people is low.
