Normally, when an outbreak or epidemic is found, the first order of business is to confirm a situation is actually happening. Once that is confirmed, the next step is to identify the cause. In the case of Zika virus, both these steps happened without much concern. Unfortunately, the rest of the epidemiological investigation has been anything but a matter of routine. The reason stems from our rather rudimentary understanding of the Zika virus. While we have known about its existence for decades, only a few studies on its effect on humans have ever been conducted. This means we're learning new things every day as new studies are ordered. What this does NOT mean, however, is that we are all victims of a vast conspiracy. So let's keep that in mind as we look at what we do know so far.
