Meghan Markle and Prince Harry announced their pregnancy this morning as they kicked off a 16-day tour that includes stops in Australia, New Zealand, Fiji and Tonga.
But the trip is raising some concerns as doctors advise that women like Meghan, who is 12 weeks pregnant, should not travel to areas that pose risks of Zika infection.
"In Obstetrics, my advice is always to err on the side of caution," Dr. Jennifer Ashton, ABC News' chief health and medical correspondent, said in a statement to "Good Morning America." "But many decisions that arise during pregnancy are for the pregnant woman, her partner and her OB or midwife to make."
The Zika virus primarily spreads through infected mosquitoes, according to the Centers for Disease Control and Prevention. Zika can also be transmitted through sex without a condom with someone who was infected by the virus, even if that person does not show symptoms of Zika. There is currently no vaccine to prevent or medicine to treat Zika, and it can be passed from a pregnant woman to her fetus. Infection during pregnancy can cause a birth defect called microcephaly and other severe fetal brain defects, according to the CDC.
Along with other precautions, the CDC recommends against pregnant women traveling to places with documented or likely Zika virus transmission.
Here's more CDC recommendations for protecting yourself against Zika during pregnancy.
