Virulence describes a pathogens severity or infectiousness.
It is possible that a more infectious and less severe strain of the coronavirus could explain different outcomes in the east and west. There are a number of different strains out there.
Studies involving gene sequencing to identify strains and outcomes across different populations would be necessary to prove this one way or the other.
It could be that a solution to this would be to vaccinate people with the mild strain (as advocated by some learned people).
- gizmo 6y agoIt's not inconceivable, but it would be a very convenient coincidence. I take it this less harmful strain also got to Greece, Belarus, Morocco, Bolivia, and Florida? Outperformance in Asia is much better explained by partial immunity created by prior exposure to SARS/MERS. But even that doesn't explain why regions all over the world are hardly affected by covid19, including those that didn't have prior SARS/MERS exposure. Data strongly suggests that this coronavirus is seasonal just like other coronaviruses and not especially deadly so Controlled Voluntary Infection shouldn't even be necessary (but it would work).
