Texas Updates Zika Testing Guidelines

On April 2, 2018, DSHS updated its testing guidance for pregnant women in Texas to match the CDC guidance for testing women with possible Zika exposure:

  • Pregnant women who live in Cameron, Hidalgo, Kinney, Maverick, Starr, Val Verde, Webb, Willacy, and Zapata counties should be tested three times during pregnancy using PCR only.
  • Elsewhere in the state, pregnant women with no symptoms but recent possible exposure (for example, women who have traveled to areas with ongoing Zika transmission) should be tested as soon as possible up to 12 weeks after exposure using PCR only.


The guidance for testing non-pregnant residents remains the same:

  • Residents of the nine higher-risk counties with a rash plus one other common Zika symptom (fever, joint pain or conjunctivitis) should be tested.
  • Residents of other parts of the state with three or more Zika symptoms should be tested.


For additional details on the updated testing guidelines, read the Health Alert.
