It's consistent with natural selection. Cases inside Hubei likely have fewer viral generations (= less mutation) than cases outside. Additionally, every case outside has a population bottleneck in that it was transmitted through a host that was well enough to travel. The most virulent cases would be expected to sicken their hosts and discourage travel or extensive social contact.
- sudosysgen 7y agoHubei is estimated as being max at the 5th generation, and genomes so far have indicated less than 0.02% genetic variance. I don't see evolution playing a succincts) significant role in this timescale.
- mhandley 7y agoSurely all current cases have experienced roughly the same number of viral generations? A death outside Hubei today will be caused by a virus with roughly the same number of generations as a death inside Hubei. Yet a smaller fraction seems to be dying outside Hubei. Other possible explanations are that the healthcare system in Hubei is overwhelmed, so more patients die, or alternatively they're just too busy to accurately report recoveries.
