Just thought I'd post some nice pics of kids in Japan practicing #kyokushin karate.
Some older kids.
It's pretty full on. Full contact karate. One day I hope to return to this. I miss it. #longcovid
Just a couple more images, for a little context.
Karate photos from Hannan Dojo on Instagram

Wow. Talk about propaganda.

Sweden's leading newspaper, @dagensnyheter, booked an interview with a Swede living in New Zealand. After she old them she supported the NZ strategy, they cancelled the interview, instead going with an "anti-lockdown" Swede.
They failed to even report that nearly 9 in 10 New Zealanders support their Zero Covid approach, and only added some other Swedess in NZ views after many of them wrote to protest.

Perspective -

Sweden 14692* reported Covid-19 deaths
New Zealand 27 reported Covid-19 deaths
* Sweden has not reported any new Covid deaths since Tuesday due to a "system update"

Jesus F Christ.

Swedish "Science Radio" does not under Science.

They claim there that the risk of getting Covid-19 is just 0.2% after a 2nd vaccine. >
First of all, after 18 freaking months they apparently don't understand that Covid-19 is the disease state. The paper they cite is talking about infection with sars-cov-2. If you don't get sick, you don't have Covid-19, you're just infected with the virus >
But most seriously, because only 0.2% of a certain group of people (Covid symptom study) got infected following vaccination, they conclude the risk of infection is only 0.2%!

🦘In a surprising turn of events, despite the relaxation of restrictions to decrease the spread of a serious virus, the virus continues to spread with exponential growth in Sweden. 🙄

Nobody could possibly have predicted this, especially given what happened last year.🦘
🦘Oddly, despite cases increasing exponentially, hospitalisations are *also increasing*. 👀None of this, obviously, makes any sense.🦘
🦘Fortunately, Swedish schools open this week for compulsory in-person teaching with most having no ventilation (windows don't open), no HEPA filters or CO2 monitors, and definitely no masks. These lack of measures should help prevent the spread of infection in children.🦘

Sweden's first Covid press conference in 6 weeks today. When asked if they've estimated how many kids are going to be infected in schools, the Health Authority says they've not.

So I have.

Varsågod @Folkhalsomynd @Skolverket @socialstyrelsen @lenahallengren @Anna_Ekstrom
I did some quick calculations based on R_e last week, but in this thread I'll look more directly at the real world consequences.

This paper looked at risk of hospitalisation, ICU admission, and mortality by age.

Note that *this is pre-delta*. Still "fog of war" data, but there are many indications outcomes for delta is worse, so numbers in this thread may be an underestimate.

New cases per day (blue line is rolling average) vs @Folkhalsomynd modelling in July (red line).

Thanks @BishopBlougram for the heads up.
The July modelling included an assumption that delta was 50% more infections than Alfa. This is within the ballpark of most estimates at the time, it may be higher.

They also assume that if vaccinated or previously infected (by any variant) you cannot be infected again.
This I don't think is enough to explain how the model was so very wrong, though a problem I have with this type of modelling in general is so many of the variables are assumptions, and with a phenomenon of exponential growth, small errors can end up being very significant.
