I would like to know what would happen if a new virus arose which could not be cured and which managed to escape the infected areas (and any quarantine zones). In order to scope this question I'm not interested in how humanity would adapt I want to know about how the infected rates/death tolls over time based on patterns from historical epidemics.
- Let's assume the virus is spread through body fluids (seems common enough)
- No human doctor can treat it
I want to know
- Assuming there was no medical cure would everyone die?
- Or is it likely some people would be naturally immune/recover?
- What would happen once the virus infected everyone? Would the entire population die off? Would it subside (like a predator) then reassert itself when humanity has rebuilt itself?
The answer I'm looking for will look at major outbreaks from the past and extrapolate what would happen if something similar happened today. Just to repeat myself I'm not looking for humanity's response to a global contagion, I'm looking for the patterns the virus would follow.
