[...] even less than ideal masks, when all parties are masked, are indeed effective at mitigating the spread of the virus.
That is knowledge taken for granted in Japan since middle of last year. They used their supercomputer to simulate particle dispersion. Result : both parties masked = best protection for all. The best result will come when everybody does what's best for themselves
and for others.
MORE OBSERVATIONS AND SOME PATHOS
Good thing over here is that masks and vaccines did not get ground up between party-political quarrels (US and EU). But then again, Japan never had a real hard lockdown. Now, with delta that might change.
Mask wearing has been common-day practice here for 1.5 years now. Compliance is and has always been in the high 90s in percentage. Back to 99.9% right now.
It's clear that here it's entered the next stage of the pandemic -- involving and affecting all those who are not yet vaccinated (including rising number of teenagers and smaller children). Absolutely no doubt about it when looking at published numbers of incidences per age groups.
Japan has always been very good at manual contact tracing (works very well when incidences are low). But they found with delta that spread within households is the biggest contributor here. If one member catches delta somewhere outside, it doesn't take three days for all other household members to get it too. So they have sort of given up relying on contact tracing plus introducing specific measures here and there and instead started weighing unprecedented restrictive measures.
Delta is not a joke ! Protect yourselves, those you love, those you don't , and everybody else.
!! Get your shots and wear masks !!
Only then they might not have to shut everything down again in your region later this year.
Nobody wants that.
And no matter what you do, please try to keep collateral to an absolute minimum. There sure will be people who would thank you for it, if they only knew it was you.
!! Don't be scared, be reasonable !!
