Ministeri Jussi Saramo julkaisi eilen 24.3. kolmannen version siitä, millä tavalla tartuntoja pitäisi analysoida kun puhutaan joululomien vaikutuksesta tartuntoihin. Johtopäätös on kuitenkin pysynyt koko ajan samana.

#FactCheck Image
Vaiheessa 1 ministeri käytti 14 päivän ilmaantuvuutta + 5 päivän itämisaikaa johtopäätöksien tekemiseen siitä, millä tavalla joululomat vaikuttivat tartuntoihin. (Se on hyvä menetelmä.)

Tässä vaihe 1 kuvana. Tämä vaihe oli voimassa 20.3.2021 saakka.

Sen jälkeen (21.3.2021) osoitin ministerin väittämän vääräksi (käyttäen 14 päivän ilmaantuvuutta + 5 päivän itämisaikaa).

Tässä vaihe 2 kuvana. Tämä vaihe oli voimassa 21.3.-24.3.

Tässä kuva, jota ministeri käytti 2. vaiheessa (21.-24.3.)

- 14 päivän ilmaantuvuuden + 5 päivän itämisajasta siirryttiin käyttämään päiväkohtaista dataa
- samalla siirryttiin tekemällä johtopäätös katsomalla kuvaa.

Se tapa, miten ministeri vetää johtopäätöksiä muuttui toiseen kertaan 24. maaliskuuta. Tässä versiossa johtopäätökset joululomien vaikutuksesta tartuntoihin saadaan katsomalla jompaa kumpaa kuvaa. (Johtopäätös ei kuitenkaan muuttunut.)

Tässä kolmannessa vaiheessa (24.3. lähtien)
- johtopäätös saadaan katsomalla kuvaa (eikä laskemalla)
- voidaan käyttää joko päiväkohtaista dataa tai 14 päivän ilmaantuvuutta

Tässä yhteenveto siitä, miten ministeri Saramon tapa analysoida koulujen joululomien vaikutusta Suomen koronavirustartuntoihin on tähän mennessä kehittynyt.

This is an important moment.

After more than five years of silence, mainstream media has begun to acknowledge that C19 can harm T cells, and to discuss the consequences that follow. @fitterhappierAJ was one of the first, if not the first, to talk about this.

Dr. Leonardi has provided a significant amount of direction for me. In particular, he has been interviewed in some excellent articles that have withstood the test of time. Here is one of them.

We have seen it all.
- in 2020, they said that our health systems are so robust that this disease wouldn't come here
- then they wanted them infected. C19 was de facto allowed to spread in schools. Only a small fraction of <12 year olds received ...

Something is causing injuries among young children.

Something changed in 2022. Before that, the numbers were generally falling. Wonder what it could be.
2/x Image
After 2022, 1-6 year olds have overtaken a total of three other age groups (50-64, 15-24 and 65-74 year olds), and are now clearly above the total population average. All injuries (S00-S99).

Finland's epidemic 23 Dec 2025: amount of virus in wastewater appears to have risen above the first Omicron wave. Post-Omicron baseline is permanently higher than pre-Omicron; repeated waves are showing no diminishing.
1/x Image
Post-Omicron baseline is permanently higher than pre-Omicron
- before late 2021, levels were mostly 10³–10⁴.
- from 2022 onward, even troughs sit around 10⁵, or 10-100x higher
- C19 has become endemic
- constant background transmission, even outside waves
2/x Image
Repeated large waves in 2023–2024, not diminishing. Notable peaks:
- Apr 2023
- Nov 2023 (highest for the entire pandemic)
- Dec 2024

These peaks are:
- comparable to or higher than Omicron 2022
- evidence against a simple “each wave gets smaller” narrative
