This opinion, by Tara Kirk Sell, was first published in the Baltimore Sun on June 6th.
With the Zika outbreak in the Americas raging and the growth of scientific support about potential birth defects from maternal infection, some in public health have called for the 2016 Summer Olympics in Rio to be postponed or moved. As a fellow public health researcher and a pregnant Olympian swimmer and silver medalist at the 2004 Olympics in Athens, I have a close-up perspective on both sides of this issue and believe this opinion does not balance the risks appropriately.
Importantly, there simply isn't enough evidence at this point to support a large-scale, intrusive public health action that will devastate so many people. While Zika can cause severe outcomes in some, the vast majority of people who are infected will not experience symptoms. Newly emerging scientific evidence has shown clear connection between Zika and birth defects, but there are simple protective actions that can be taken to reduce the risk of infection. Often, decision makers justify extreme public health interventions "out of an abundance of caution" and a desire to remove all risk from a situation. But these arguments overlook any real consideration of the costs of taking these unwarranted actions, which are often high for those people who are affected by them.
