ICYMI - In Canada, the cases of COVID-19 and deaths are declining. Here's the story behind the numbers
It’s too soon to know. The true case fatality rate won’t be known until the end of the pandemic, Deonandan says.
Black and South Asian people were nearly two times more likely to suffer a COVID-related death than white people, for reasons that aren’t fully clear. The most socio-economically deprived were 1.
, 61 per cent survived to be sent home alive at the time study was published. From the original reports out of China, “they were reporting crazy things, like 90 per cent morality for people on ventilators,” Ferguson says. The experience here suggests the prognosis for those who do get critically sick may not be as bleak as the early reports made it out to be. That’s partly because the system was better prepared. Canada’s ICU’s weren’t saturated and stressed to the breaking point.
So what is the true mortality rate? It’s hard to nail down. In March, the World Health Organization pegged the case fatality rate — the fraction of known cases that die — at 3.6 per cent globally. The case fatality rate is the ratio between the number of confirmed deaths from the virus and the number of confirmed cases, not the actual number of cases or infected people that are floating out around there.
“That should not be confused with having a less severe disease present in the community,” Deonandan says. Cleaning surfaces is still important, Deonandan says, but perhaps we don’t have to be obsessed with it. The WHO this week acknowledged airborne transmission is a thing, but it’ s not the primary way people get COVID-19. It’s by droplets, and masks diminish droplet transmission, Deonadan says. “It tells me we have the tools to contain this well.”
