I love the concept of Disease X, but I’m undecided about whether or not I’d like to see it in the movie canon.
Honestly the idea of dinosaur Scrapie is quite terrifying, but it’s even more terrifying to think that people were eating the dino corpses at some point prior to tlw novel and were probably ending up with some type of dinosaur vCJD. Prion diseases aren’t exactly contagious, but they can be contracted through eating infected meat, and if all those people were really eating the washed up corpses from the beach then cases of vCJD (or at least something similar) would skyrocket.
Although, if DX was to end up in the Jurassic World movies, I do think it would make for a curious story. Say, for instance, one of the herbivores ended up with a sporadic prion disease, and then its remains were ravaged by the compys. Then all the compys would have consumed infected meat, and would likely spread it to other species that consumed them (assuming that the disease in question could jump the species barrier). Eventually the disease could make its way to humans if people were to eat infected dinosaur meat. Then you could have a whole story about the government trying to downplay the situation (like the British government did with BSE in the 90s) and a group of reporters and scientists trying to find the origin of the disease.
It would probably end up being very cliche and trope-y, but there are a lot of interesting concepts for DX if they ever do decide to adapt it.
I’m still not completely sure about whether or not I want to see it on the big screen, though.
