Updated CDC Zika Interim Response Plan: This document describes updated guidance and resources from the CDC for responding to cases of Zika virus infection in the continental United States and Hawaii. This guidance serves as a reference for public health decision-making and is targeted to state, local, and tribal jurisdictions, which are responsible for responding to Zika virus disease in their communities. 

NEW Web resourceGuidance for Areas with Local Zika Virus Transmission in the Continental United States and Hawaii”: CDC has issued guidance for travel, prevention, testing, and preconception counseling related to risks for pregnant women and couples considering conception in areas of active Zika virus transmission in the continental United States and Hawaii. CDC has identified two types of geographic areas to describe where Zika virus-related domestic guidance applies: Zika active transmission areas (designated as red areas) and Zika cautionary areas (designated as yellow areas). 

Prolonged IgM Antibody Response in People Infected with Zika Virus: Implications for Interpreting Serologic Testing Results for Pregnant Women: 

CDC issued a Health Advisory Notice  with updated guidance for healthcare professionals to interpret Zika test results for women who live in, or frequently travel (daily or weekly) to areas with a CDC Zika travel notice.

CDC recommends the following guidance for healthcare professionals evaluating women without symptoms who had potential Zika exposure—particularly women who live in or frequently travel (daily or weekly) to areas with CDC Zika travel notices. Use of these tests may be helpful, but may not always be conclusive, in distinguishing how recent the infection is.  

  • Screen pregnant women for risk of Zika exposure and symptoms of Zika. Test pregnant women promptly, using nucleic acid testing (NAT), if they develop symptoms at any point during pregnancy or if their sexual partner tests positive for Zika virus infection;
  • Consider NAT testing at least once during each trimester of pregnancy to detect evidence of Zika virus, unless a previous test has been positive;
  • Consider testing specimens obtained during amniocentesis to detect evidence of Zika virus if amniocentesis is performed for other reasons;
  • Counsel all pregnant women each trimester about the limitations of Zika testing.
