Today, a study in the journal Neurology brings the surprising news that having herpes could be even worse than you think it is. The chronic, cold sore-causing virus may also wreak havoc on the brain, with a recent study conducted by Columbia University and the University of Miami suggesting that people suffering from high levels of infection with herpes and other common viruses may be more likely to suffer cognitive decline as they age than their uninfected peers.
How did all of my polar bears get herpes? It's an uncomfortable question that we've all been forced to ask ourselves at one point or another. At least, all of us who are zookeepers at Germany's Wuppertal Zoo, where no less than 10 polar bears came down with the virus in 2010. Still -- awkward, right? The good news is this: there is probably a perfectly reasonable explanation for how this happened, and chances are it involves no weird cross-species makeout sessions. The bad news? Nobody knows what that answer is. Right now, it's just a story of bizarre new strains of herpes virus and a dead polar bear, which we can all agree is super-sad.
