Zika virus during pregnancy

Zika virus is mainly spread through mosquito bites and can also be passed through sex. Some people have no symptoms; others develop a mild fever, rash, red eyes, joint pain or headache. Pregnancy care teams take a travel history and ask about sexual exposure because the virus can pass from a pregnant person to the developing baby. The concern is not based on how unwell the pregnant person feels: a mild illness or no noticeable illness still deserves assessment after a relevant exposure.

The team will consider where and when exposure may have happened, any symptoms, the stage of pregnancy and local testing advice. This helps them decide whether testing, ultrasound follow-up or other monitoring is appropriate.

Contact your obstetrician, midwife or GP promptly if you are pregnant and have travelled to an area with Zika transmission, had mosquito exposure there, or had sex with someone who may have been exposed. Write down travel dates, countries visited, symptom dates and any relevant sexual exposure before the appointment.

Avoid further mosquito bites by using pregnancy-appropriate bite prevention and follow individual travel advice. Do not start, stop or change medicines because of a suspected exposure without checking with the clinician managing your pregnancy.

Seek urgent medical help for vaginal bleeding, severe abdominal pain, fainting, trouble breathing, severe headache with visual changes, or a marked change in your usual pregnancy symptoms. These symptoms need assessment whether or not Zika is involved. Arrange a prompt non-emergency review for a new rash, fever, red eyes, joint pain or headache after possible exposure.

Ask whether your itinerary counts as a possible exposure, whether testing is useful at this point, and what pregnancy monitoring is recommended. You can also ask what precautions apply to future travel and sexual contact during the pregnancy.
