Assessing pregnant women
All pregnant woman in the US should be assessed for possible Zika virus exposure at each prenatal visit.
Who should be tested for Zika?
** Sexual exposure includes vaginal sex, oral sex, anal sex, or other activities that might expose a partner to genital secretions.
Individuals who did not travel to a Zika affected area but have had > 3 symptoms of Zika virus infection (fever, rash, arthralgias, or conjunctivitis) in the past 14 days not explained by another etiology AND have a history of mosquito bite(s) within 2 weeks of symptom onset may be considered for Zika virus testing.

What tests should be done if Zika virus is suspected?
For an algorithm with testing and interpretation recommendations for pregnant women with possible exposure to Zika virus, see http://dx.doi.org/10.15585/mmwr.mm6529e1 (Oduyebo T, Igbinosa I, Petersen EE, et al.

Where can test specimens be sent? Testing for Zika virus is now available through several commercial labs, in addition to the NC State Lab of Public Health. (See attachment for more details.)
How do I manage infants with possible Zika virus infection?
