r0 is apparently around 5-6 with no special precautions. Even in china with everything they have done, locking people in their homes and gassing and quarantining, it´s still at like 2-3.
This thing can't be stopped. Unless it burns itself out faster than it can spread, it's going global for sure.
Oh and in regards to lethality: Calculate deaths/(deaths+cured).
Don't know why people keep using total number of infected. It makes no sense. Some of those people are going to die.
