Long COVID in children doubles risk of poor grades Findings indicate long-COVID leads to academic and social difficulties in children, highlighting the importance of addressing their unique educational needs.

All that school absenteeism that education bureaucrats & the #Media have been fretting about lately, without mentioning an #OngoingPandemic of an injurious #AirborneVirus?

Solution: #CleanTheAir & #PreventLongCOVID

It's not rocket science 🚀

COVID vaccines are tied to less hospital care, long COVID, and economic burden.

A large study in Germany shows lower hospitalization, all-cause death rates, and health care costs in vaccinated people.

Measles outbreak means my immunocompromised son can’t leave the house without extreme safety measures Hundreds of thousands of families are making life-or-death decisions as measles continues to spread.

Yes, measles, Covid-19, flu... it does not matter, public health is a shared responsibility - our decisions impact others around us

$65 Billion Missing????

“In the Auditor General’s 2024 report, she notes that over $65 BILLION IS MISSING. Most of that was received from Ottawa as transfer payments intended for health care, but for 5 years the Ford government hadn’t kept track of where that money went! (Any guesses?)”

Finally #LongCOVID enters the conversation, & #Lockdowns EXIT 👈 sorry about this typo (courtesy of autocorrect), which quite changed the meaning of this post.

But you get the gist, "lockdowns" (protections) were not injurious.

Whereas, Long COVID (still zero cure), is a mass disabling event -

At some point the endless string of corrupt behaviour has got to catch up to Doug Ford. How will this play with all the rubes who see him as 'one of them'?

If you think Doug Ford using taxpayer funds to buy his private jet is unrelated to his trying to have jets fly from Toronto's Island Airport, I've got a failed private waterfront spa at Ontario Place, a shuttered Science Centre, and a tunnel under the 401 to sell you.

So many of us who advocated for N95s were told to avoid COVID by hand washing.

This apology doesn’t rectify the ongoing problem; the general population still thinks COVID isn’t airborne and even our hospitals aren’t instituting masking to protect our most vulnerable patients.

Canada's Covid strategy has been to not talk about Covid and vaguely encourage people to suffer quietly.

If health-related reasons (e.g., respiratory illness, mental health issues, disability) are even partly responsible for this rather dramatic increase in absences, making students' grades contingent on being present could very well make matters worse.

High school attendance drops to 40% in Ontario as government considers changes | Globalnews.ca The Ford government is currently considering giving students in grades 9 to 12 credit on their final marks if they attend class as part of new legislation.

Percentage of Ontario high school students missing 10% or more of their classes:

2017-18: 40%
2021-22: 47%
2022-23: 64%
2023-24: 59.5%
2024-25: 59.8%

ON's proposed policy solution? Award grades for attendance. Forget addressing root causes of increased absences.

Oh, chronic absenteeism after the pandemic has risen to over 60% for high school students in Ontario?

That’s because IT’S NOT AFTER THE PANDEMIC

Kids are missing school because they are sick, and this is happening on a global scale.
