Testing for Zika virus can be complex, and is not recommended for everyone. CDC has released updated guidance for testing pregnant women with possible exposure to Zika virus. As part of this guidance, CDC encourages providers to check with state or local health departments for jurisdictional recommendations, which may differ from CDC guidance based on epidemiologic considerations.
MDH continues to recommend Zika virus testing for symptomatic patients with possible Zika virus exposure, as well as pregnant women with possible Zika virus exposure, regardless of symptoms, due to ongoing transmission of Zika in many areas of the world. For questions regarding testing recommendations, healthcare providers are encouraged to contact MDH epidemiology staff. Due to current testing limitations, a screening test for possible Zika virus infection after travel is not recommended for pregnancy planning purposes. Instead, women and their partners who may become pregnant in the near future should either avoid travel to areas with risk of Zika virus or consider waiting to get pregnant after returning from an affected area. For more information, visit the CDC Zika and Pregnancy webpage.
