I don't think this is the next big one. . . .It's spread through close contact with infected body fluids (similar to Ebola) and has 80%+ fatality, with a sudden onset after a 1-3 weeks incubation. Sick people won't be walking around, spreading it, and containment is definitely easier than with an airborne. I'm betting on the flu causing the big problems this winter, will all the vaxxed people having messed-up immunity.
