COVID is AIRBORNE

Canadian Experts Share Their Recommendations

The SARS-CoV2 virus is in the air — at close range and further away.

This clear science can no longer be denied.

Occupational health specialists and others from Canada and around the world have delivered this message since the pandemic began.

Gambling with bird flu is asking for trouble — and another pandemic

The warnings are increasing. Infectious disease researchers, virologists, veterinarians, and occupational health specialists around the world are sounding alarms.

 

The stories of wild birds, mammals, poultry, cattle, and other farm animals with "bird flu" (H5N1) keep coming. The real infection numbers are greater than official reports, but no one knows by how much. Meanwhile, decision-makers and other authorities seem intent on repeating the same mistakes made with COVID-19 and SARS. 

 

Now, it has spread to people.

We can, and must, do more to protect students in higher education from the risks of post-COVID condition

Canada’s post secondary institutions have a responsibility to protect students and others on campus from the risks of post-COVID condition as a matter of campus safety.

Canada’s Chief Science Advisor, Mona Nemer, recently released the report, Dealing with the Fallout: Post-COVID Condition and its Continued Impacts on Individuals and Society.

 

Post-COVID condition (PCC), also known as “long COVID,” refers to the poorly understood and often serious health damage left by the SARS-CoV-2 virus after the acute illness appears to have passed.

The British Medical Association wrote this letter to the country’s National Health Service in December, 2023. The virus is airborne, they say; healthcare workers need respirators and ventilation, not guidance that ignores health and safety law.

Long-term outcomes following hospital admission for COVID-19 versus seasonal influenza: a cohort study

COVID-19 is worse than the flu, leading to more disability, “higher long-term risks of death and adverse health outcomes in nearly every organ system” (except respiratory - where flu takes a toll). For more about the December 14, 2023 study, see this interview.ter to the editor at the Toronto Star points out it takes more than vaccines to avoid infection.

CANADIAN EXPERIENCES WITH LONG-TERM SYMPTOMS FOLLOWING COVID-19

In December 2023, Statistics Canada said re-infections increase the odds of Long COVID. 3.5 million Canadian adults reported these long-term symptoms. Almost half have no improvements. Black Canadians are more likely to have multiple infections.

DIRECTORY of CANADIAN COVID-19 PREVENTION GROUPS

Compiled in March 2024, this directory is from the “Snapshots from the grassroots” portion of the Coalition’s March 11th webinar, The 4th Anniversary: Raising our voices about COVID in Canada.

Use the contact form below to let us know if we've missed anyone or anything.  

Groups come and go, since many involved are volunteers. Their use of social media may change.

Even if they aren’t very active today, their materials still may be useful, so they’ve been included.
