Diagnosis

Your doctor will likely ask about your medical and travel history. Be sure to describe any international trips in detail, including the countries you and your sexual partner have visited, the dates of travel, and whether you may have had contact with mosquitoes.

If your doctor suspects that you may have a Zika virus infection, he or she may recommend a blood or urine test to confirm the diagnosis. The blood or urine samples can also be used to test for other, similar mosquito-borne diseases.

If you are pregnant and don't have symptoms of Zika virus infection but you or your partner recently traveled to an area with active Zika virus transmission, ask your doctor if you need to be tested.

If you are pregnant and at risk of Zika virus infection, your doctor may also recommend one of the following procedures:

• An ultrasound to look for fetal brain problems
• Amniocentesis, which involves inserting a hollow needle into the uterus to remove a sample of amniotic fluid (amniocentesis) to be tested for the Zika virus
