Updated Zika virus testing recommendations


Zika virus

For couples who may become pregnant:

  • Testing for Zika virus is not recommended for pregnancy planning
  • Instead, women should wait at least 2 months and men should wait at least 3 months after travel to an affected area before attempting conception
  • When choosing a travel destination, it is important to consider that the ability to detect a new outbreak varies by country, and reporting of new outbreaks may be delayed several weeks to months. While the risk of Zika virus infection is highest in areas with a current outbreak, risk also exists in any country that has ever reported Zika virus cases (past or current), and potentially even in countries where the mosquito exists but no Zika virus cases have been reported. Stay informed about which countries are currently affected by Zika virus before you travel, and don’t forget to check the maps for a few months after you come home in case an outbreak was identified afterwards by looking at the CDC's Zika Travel Information page.

For couples who are currently pregnant:

  • Avoid travel to all areas where Zika virus is a risk. Check the CDC’s website for the most up-to-date information by looking at the CDC's Zika Travel Information page.
  • Couples should use condoms for the duration of the pregnancy if the male partner has traveled to an affected area within three months prior to conception or at any time during the pregnancy.
  • Call 651-201-5414 prior to submitting specimens for testing. Testing may be recommended for symptomatic patients with potential Zika virus exposure (either through travel or sexual contact) and asymptomatic pregnant women with travel to current outbreak areas.
  • MDH is no longer routinely recommending testing for asymptomatic pregnant women with recent possible exposure to Zika but no travel to current outbreak areas. These pregnancies should still be closely monitored for any abnormalities.
  • Testing may be recommended on a case-by-case basis for asymptomatic pregnant women with ongoing Zika virus exposure, travel to current outbreak areas, or prenatal ultrasound findings suggestive of congenital Zika virus infection

For infants with possible Zika virus exposure:

West Nile virus and other arboviral diseases
