The Ophidian paramyxovirus is not at all like AIDS.
AIDS is a syndrome that has as its root cause HIV (human immunodeficiency virus). You might say that AIDS is what you see at the later stages of an HIV infection. HIV infects an immune cell called the T-cell, or more specifically a CD4 helper cell. When HIV compromises your immune system, you come down with diseases that most people with a well functioning immune system don’t get. At that point, a person with HIV is said to have AIDS.
Ophidian paramyxovirus does not attack the snake’s immune system. It does not require exchange of body fluids for its transmission. The disease is thought to be transmitted through the air, and it mostly infects vipers. Sorry, but that doesn’t sound like aids. It sounds more like some kind of flu.
If Chonubrid thinks that one of his snakes had OPV, then he needs to take some action. The current recommendations to prevent ophidian paramyxovirus infection are a prolonged and strict quarantine of all new animals, and euthanisation of all suspected carriers or chronically ill snakes. If Chonubrid suspects that he had an OPV infected snake, he needs to take some actions, and getting another snake is not one of them. The chances are very slim that his snake died of OPV, but if he has real reasons to suspect something that serious, he needs to step up to the plate and do the right thing.
Below is a link from one of Duke’s web sites with detailed information about OPV. Since it was not intended for laypersons, it is not an easy read, but with a little effort, one can gain much knowledge on the subject.
