I've been publicly wondering for a while why the spread of the pandemic is so uneven. This paper has me pretty persuaded that the Japanese public health people were right, and spread is entirely dominated by a few superspreading events. https://covid.idmod.org/data/Stochasticity_heterogeneity_transmission_dynamics_SARS-CoV-2.pdf …

The key implication of the theory is that most sick people don't pass the disease on to others, but those who do are incredibly infectious. One consequence of this would be that the entire "anonymous contact tracing app" effort is completely futile, one reason I like the theory

The bigger consequence is that if we can understand the nature of the superspreading events, it's possible the pandemic could be stopped very quickly. Optimism is off-brand for me, but this is the first explanation I've seen that fits the observations well and it forces my hand

What does a world look like if is optimized to avoid this kind of spreading mechanism? Japan. That's not so bad. You can get a haircut and go drinking. No choir practice, but they won't put a padlock on the swing set, either, and old people can come out of hiding.

Oh, but the implications for sports are the worst, especially if conjectures about shouting/loud talking as a factor in spread turn out to have substance. Hope everyone likes golf!
