As Zika danger wanes, health agencies ease travel warnings for women who are pregnant or plan to become pregnant

Until Zika, there had never been a mosquito-borne virus that could cause serious birth defects on such a large scale. Among the most devastating consequences of Zika is microcephaly, a condition in which babies are born with abnormally small heads and underdeveloped brains. The danger to a developing fetus is most severe during the first and second trimesters of pregnancy.
In the continental United States, mosquito control measures helped stop the spread of the virus, and there has been no local transmission since 2018. For the 88 countries and regions that have previously reported cases of the virus, and where there is currently no outbreak, “Zika virus has probably fallen below the radar,” said Martin Cetron, director of CDC’s Division of Global Migration and Quarantine, which tracks disease outbreaks overseas and in the United States.
“I get about four or five calls a week from concerned couples who are thinking of conceiving in the future,” Ko said. Risk still exists in much of Southeast Asia and South Asia. Though it is much lower than at the height of the epidemic in the Americas, he said, “that’s hard to tell a woman or a couple who wants to conceive and who wants to have it be absolutely 100 percent risk-free.”
Riley recently spoke with a patient who was 26 weeks pregnant and planning to travel to the Bahamas in a few weeks. She wanted to know Riley’s assessment. On the CDC website, the information notes that the Bahamas has reported past or current Zika transmission, but it also says there is no accurate information on the current level of risk.
