CDC's Zika Advisory Signals Stark, Quick Shift in Approach

In a matter of days, the Centers for Disease Control pivoted from a conservative approach to the Zika outbreak to issuing a travel advisory and suggesting every pregnant woman get tested, regardless of travel, according to a story on The Hill.

What changed? The four reported cases in Florida of Zika being transmitted through mosquitoes vs. through human contact, which increased to 10 this week.

But the directive for testing also signals a "tacit admission" that Zika might be a bigger problem than originally thought, Meghan May, a Ph.D and Associate Professor of Microbiology and Infectious Diseases, wrote in a blog for The Hill. 

"This does not mean that those issuing the guidelines don't know what is going on, or that they are being flippant," May wrote.

"It means that we are learning more and more, and implementing changes with each new finding. That is the best thing that can be done when the situation changes day to day."
