Scott Lanyon, director of the Bell Museum, has an article on two disease we should worry about, VHSv and EAS.
Personally, I think VHSv is the worst. It’s a virus that causes hemorrhagic septicemia in fish; just from the name you know it’s bad, involving blood and sepsis. My most horrible experience raising zebrafish was the time hemorrhagic septicemia swept through my colony and I had to euthanize every animal and bleach every last bit of plumbing to eradicate it. This disease has been detected in waters of Wisconsin, and it’s definitely not good.
EAS may not be as dramatically gory and lethal in its effects, but it strikes humans directly. It’s Evolution Avoidance Syndrome, and it causes the brains of scientists and journalists to seize up when circumstances are appropriate to discuss evolution in public. Apparently, we want local fish populations to develop, acquire, improve or have arise resistance to the hemorrhagic septicemia virus; we can’t possibly suggest that evolution might be at work.
