Ah, chickenpox, that pesky old childhood illness. And that’s all it is, right? Just a mild, routine infection that we all used to catch until the vaccine came around? Not quite. In this episode, we learn that, when it comes to the varicella-zoster virus, not everything is as it seems. We explore the complex nature of this virus, how it can make you kinda sick and then how it can make you really, really sick. After that, we dive into the evolutionary origins of this virus and the different infections it causes (spoiler alert: shingles as a viral survival strategy?!). And finally we trace its human history from discovery to vaccine to where we stand with chickenpox and shingles today.
