Comment of the Week
“It is indeed warm in Hawaii, but most people here like to avoid the heat as much as those in any other warm region (such as Florida), so it’s not clear that Hawaii’s lower infection rate is largely due to the weather.
While isolation from other states and quarantine rules surely do play a role (though many break quarantine as it’s largely unenforceable), a likely bigger factor is that the vast majority of people in Hawaii consistently wear a face covering and provide distance when around others.
This may be due in part to Hawaii’s culture, where the concept of “family” (?ohana) extends to the entire community and caring about elders and others is fundamental, but I am glad for it nonetheless.”
