I was just thinking it's lucky that the common cold is rarely fatal, since it must have a similar R0 to measles. But then I guess there must have been super virulent strains that killed off entire populations, with that strain also going extinct due to lack of hosts!

It's actually pretty low (in comparision) at only a 2-4 from what I've heard in the past. There's just nothing stopping it. Not a cold but that spanish flu (1918) was a bit of a shitter. It's best not to think about this in the context of weaponized smallpox (not that you we're, sorry for bringing it up).
That gives me an idea just how fast measles can spread. Weaponized diseases are definitely super scary. I guess the main reason no one uses them is because the bugs don’t know they’re only supposed to attack people from the other country
