The CEO of New York's Mount Sinai Health System said Thursday if he were a pregnant woman he would not go to the summer Olympics in Rio because of the threat of the mosquito-born Zika virus that's been linked to birth defects.
"I'm not an infectious disease expert, but as a general way I think that pregnant women really have to watch out here. So I would err on the side of caution," Dr. Ken Davis told CNBC's "Squawk Box." Brazil has been ground zero for Zika infections.
Pregnant women who get Zika are at risk for their babies to be born with the microcephaly and other severe abnormalities. "This is scary time," said Davis.
For women during the summer months in the U.S., Davis said, "what you might think about is delaying pregnancy." He also advised mothers-to-be to stay inside or "you're going to have long sleeves and long pants and you're going to go out with insecticide."
