Will the Olympics Spread the Zika Virus?

Experts disagree on how the games might affect Zika across the globe.

“Zika is a threat that we don’t really understand very well,” Art Caplan, a bioethicist at NYU Langone Medical Center, told ABC News.

Caplan co-authored an open letter to the Olympic Committee suggesting they postpone or move the games “in the name of public health.” To date, the letter has been signed by 240 doctors, researchers and ethicists across the globe.

Travel to the Olympics represents “far less than one percent” of the total travel to and from countries currently affected by Zika, Cetron said, citing a recent CDC report.

Though he disagrees with the authors of the letter, he said, "Their hearts were in the right place."

With the games set to kick off this Friday, both experts agree on one thing: Anyone traveling to the games should take precautions to prevent mosquito bites and avoid infecting others.
