New Facts for a New Pandemic

With the majority of Covid-19 cases in Canada now being the variants of concern (VOCs), it is time to update what we know.

Here is the science as of today (Ontario, April 10, 2021):


· Covid-19 is airborne: the virus can hang suspended in the air for hours and travel much further than 2m (6’), especially indoors in inadequately ventilated spaces* [1] [2]

· The virus can be spread to others from someone who is infected but not showing symptoms. This includes people who have not yet developed symptoms (pre-symptomatic) and those who never develop symptoms (asymptomatic)[3]

· The majority of Covid-19 cases in Canada are now the variants of concern, which are 1.2–2.2 times more contagious, and 60% more deadly[4] [5]

· The highest risk individuals for COVID-19 infection in Ontario are now young, healthy people 10–39,[6] [7] [8]

· A single dose of current approved vaccines provides protection against severe illness, but you are not fully protected until two weeks after your second dose; the level of protection may change as variants evolve[9]

· Cloth masks do not offer enough protection from Covid-19 indoors unless they are lined with polypropylene; KN95 masks or those with similar levels of filtration are recommended[10]

· Mask fit is crucial; even small gaps reduce your protection. Check your fit:

· Outdoors is safer than indoors; transmission is greatly reduced (at least 19 times), but transmission can occur in close or crowded conditions and masking further reduces risk [11]

Seriousness of Illness

· Young healthy people with Covid-19 are deteriorating quickly at much higher rates[12]

· Brain disorders (neurological or psychiatric diagnosis)* affect 1 in 3 Covid-19 survivors [13]

· 1 in 4 people diagnosed with even mild cases Covid-19 report long Covid-19 symptoms months after recovering[14]

· The death toll of Covid-19 is likely much higher than official numbers as evidenced by the much higher than average expected deaths all over the world[15] [16]
