4. Viruses impact different populations differently

It isn’t just masks and vaccination statuses. Those just happen to be the things that public policy can best impact.

Sometimes they spike rapidly with a high implied Rnaught and then fade just as quickly without hitting the whole population - but you can’t know that in advance or infer it from the same path in an area with different genetics/climate/etc.

Similarly, it could be less severe (symptom-wise) there, but worse here… and vice-Versa

We’ll find out soon enough.
