1. I've had a surprising number of conversations about Covid-19 over the past week or so, all sparked by the fact that I was, as always, wearing an FFP2 respirator. People in healthcare facilities, taxi drivers, people on trains and buses.

Could you please share this survey with Canadian university students in your life? Thank you.

COVID & other respiratory illnesses linked to new-onset vascular dementia in older adults.

When we know better we (should) do better…

Avoid COVID + ALL respiratory illnesses.

“Rates of self-reported cognitive disability among U.S. adults are on the increase, driven largely by a surprising jump among young adults ages 18 to 39, according to a new Yale study.”

It’s hard to describe how creepy and unsettling it is being one of the few people at a medical facility wearing a mask now, who knows a dangerous virus continues to freely circulate in the air.

How could public health fail us all so badly? How could we fail each other so spectacularly? #COVID

Scientists Finally Reveal Biological Basis of Long COVID Brain Fog.

Patients with brain fog may have disrupted AMPA receptor (AMPAR) expression—key molecules for memory and learning. Imaging of Long COVID patients showed elevated AMPAR density tied to more severe cognitive impairment.

For many COVID-aware people, parents in particular, the fall season represents one big gaslighting extravaganza…let’s be clear, it is NOT normal, ok, valuable, or good in any way for children to be repeatedly infected with a virus that can impact every organ of the body.

Children & adolescents reinfected with SARS-CoV-2 face a significantly higher risk of …”myocarditis, changes in taste & smell, thrombophlebitis & thromboembolism, heart disease, acute kidney injury,… generalised pain, arrhythmias, abnormal liver enzymes, ...”

I agree with Kelly.

From someone specializing in mental health: an anxiety disorder is defined as overreacting to a threat.

Many rationally choose to protect ourselves from an airborne virus by the simple act of wearing a mask when needed. Just like wearing seatbelts makes sense.

I'm going to try to change your perspective on COVID in under 2 minutes.

Never wonder whether it's COVID or FLU again.

ANNOUNCING THE FIRST combo rapid tests FOR HOME, approved by Health Canada.

Detect COVID, FLU A, and FLU B with just one swab.

This is a great tool to have ready the next time a family member isn't feeling well.

Be the kind & considerate person you are. Don’t let the negativity in the world change you.
