Yeah, most reports I'm seeing say incubation of about a week. But, even that's a long time with modern travel. You can be all over the globe in 7 days!
However, the only good news (if it can be called "good news") that I've been able to glean is that the fatalities I read about seemed to be predominantly older people (70's, 80's) who also had other serious health issues prior to picking up the virus. Obviously, I don't want to see ANYONE dying(!)… but from that, can we infer that relatively healthy people with decent immune systems have been able to recover from this? If that's the case, it could keep the fatality rate from being as high as it otherwise might be. When diseases start taking the young & healthy as well as the elderly & infirm, the death rates can really skyrocket.
