Ontario covid-19 cases, deaths, and testing.

Weekly all-cause deaths and deaths with/from Covid-19 in Ontario, including % of deaths attributed to Covid-19.

Note: Covid-19 is often not a wholly distinct and separate cause of death as there are other medical conditions involved in many cases.

There are also cases in which it is not even a cause of death, but the individual had tested positive sometime prior to their death.

Ontario total weekly deaths Jan 2010-Sept 2020.

Covid-19 has been a crisis in Ontario's long-term care (LTC) system vs. among the general public.

Covid-19 deaths per million by age cohort and for long-term care residents.

The 80+ age cohort accounts for 52% of all-cause deaths in Ontario and 69% of deaths from or with Covid-19, but only 4% of the population.

In contrast, children account for 22% of the pop. but only 1% of all-cause deaths in Ontario and 0% (0.02%) of deaths from or with Covid-19.

The silver lining of mass PCR testing: a falling CFR.

Ontario – Cumulative case fatality rate (CFR). The proportion of cases (positive test results) resulting in death (yellow line). (Cumulative reported deaths divided by cumulative cases.)

Ontario – Case survival rates (= 100% - case fatality rate) by age.

Ontario Fall/Winter season: May be able to declare a peak when average week-over-week growth reaches zero.
