First, the abstract is from 2001, so the info is not that old. Your first posting begged the question, “How do you know that your snake that died had the Ophidian Paramyxo Virus?”
The link listed the symptoms that snakes show when they are infected, and the general course of the disease. It also noted that the disease has been found in Corn Snakes, but that it mostly infects vipers.
My point is that if your snake didn't show the classic symptoms, and it was not a viper; then the odds are that it didn't die of that virus. You should have taken it to a vet if you had concerns.
The University of Georgia has a great reputation for its research. At the time of the page's posting, you can be sure that it was reviewed by one of the students' faculty advisors, and all information was current and up to date at that time. The students were working to produce a simple test for the virus that could be done at a zoo or in a vet's office to give a quick and definitive diagnosis. To criticize the abstract of their research project is petty and uncalled for.
It seems a little silly to me to worry about a disease that none of your snakes have ever been diagnosed by a professional to have.
