COVID-19 - Historic
Info & Stats (2020 - Aug 2023) (Global, Canada, and Ontario) |
*** HISTORICAL INFORMATION BELOW (Last Updated: August 2023) ***
This page contains links to useful information and historic graphs tracking the latest daily new confirmed cases of COVID-19 from a Global, Canada, Ontario, and Quebec perspective and also hospitalization & testing information for Ontario from early 2020 to around April 2022 when Canada stopped providing access to PCR testing to the general public. Some Ontario hospitalization and death information is available to August 2023. There are also graphs for each Canadian province and territory showing the 7-day rolling average to see which ones are controlling their outbreak the best (updated weekly). Finally there are charts showing both the most common adult and pediatric signs and symptoms of infection and the most common underlying medical conditions that lead to hospitalization. There is an Open Source epidemiological COVID-19 data set for Canada with visualizations. You can also find graphs of cumulative cases and deaths for Canada and all the provinces on this site and also a site that shows maps and other information for Canada.

In the testing stats, you want to see that a location is completing enough tests every day to have a 3% or lower positive rate, otherwise they may not be doing enough testing to get a full picture of their outbreak.

Ontario Cases, Hospitalization & Deaths by Age Group:
The following graphs show the # of new cases and percentage per 100K population in Ontario by age group over the past 2 weeks.
These graphs below show the Ontario COVID hospitalization rate (per 100K population) grouped by age over the previous 2 weeks from each time point. You can access the latest data and longer term trends from Public Health Ontario.
The first graph shows the % share of hospitalization rate so people can more easily see the impact of various age groups, specifically the youngest and oldest populations from August 2022 to the present (Omicron BA.4/5, BQ.1, XBB.1.5 and newer).
The second graph shows a more traditional representation of the actual hospitalization rate per 100K population for each age group from August 2022 to the present (Omicron BA.4/5, BQ.1, XBB.1.5 and newer).
The following graphs show the # of new hospitalizations and percentage per 100K population in Ontario by age group over the past 2 weeks.
These graphs below show the Ontario COVID death rate (per 100K population) grouped by age over the previous 2 weeks from each time point. You can access the latest data and longer term trends from Public Health Ontario.
The first graph shows the % share of death rate so people can more easily see the impact of various age groups from September 2022 to the present (Omicron BA.4/5, BQ.1, XBB.1.5 and newer).
The second graph shows a more traditional representation of the actual death rate per 100K population for each age group from September 2022 to the present (Omicron BA.4/5, BQ.1, XBB.1.5 and newer).

Total worldwide confirmed cases now exceeds 82 million and 1.8 million deaths. It took 67 days to reach the first 100,000 cases, 11 days for the next 100,000, 4 days for the third 100,000, ~2 days for the fourth 100,000, less than 2 days until May 21, 2020 and less than a day for every 100,000 since.

**NOTE**: Since parts of Canada are no longer testing the general public for COVID-19 or do not have adequate testing capacity, case counts are no longer accurate as of the end of 2021 but are now more reflective of the health care worker environment, LTC, and high risk settings that are prioritized for testing.

The following graph shows the number of tests completed to find each confirmed COVID-19 case for the provinces of Ontario and Quebec over time. The higher the number, the greater the ratio of testing each province is doing. For comparison, as of June 28, 2020, countries that had their outbreaks well under control such as Australia completed 310 tests for every confirmed case, Thailand has 148, and South Korea has 99 tests for every confirmed case according to worldometers.info. Countries not doing so well with their outbreaks such as the Ukraine are doing 15 tests for every confirmed case, USA has 12, South Africa has 11, Mexico has 2.5, and Brazil has only 2.2 tests for every confirmed case.

Canadian Provinces & Territories: Which are doing best?
These graphs show the 7-day rolling average of *new* cases in each province and territory in Canada to see which ones are doing the best at controlling their COVID-19 outbreak. Green is winning, yellow is nearly there, and red needs action. Each graph uses its own scale to show the curve of the epidemic for that province or territory. It is not about the number of cases in one province vs another, but how each province is controlling their own epidemic, whether cases are increasing, decreasing, or flat. These graphs will be updated once a week on Sundays and are inspired by the global stats provided here.This is a different view looking at a more recent window of time (since July 1, 2020) and adjusting the 7-day average new daily cases to be on the same scale per 1 million population so you can better compare directly to each other. You can also see a comparison to States in the USA here.

Adult and Pediatric - Signs & Symptoms:
The CDC looked at confirmed cases in the USA from Jan. 22 to May 30, 2020 where they had over 1,761,503 cases and 103,700 deaths. While 22% of their population consists of infants, children, and adolescents aged less than 18 years (children) only 5.3% of COVID-19 cases were among children. The percentage of hospitalizations for pediatric patients was also lower at 3% compared to 14.6% of adult patients being hospitalized. Children less than 1 year of age accounted for the highest percentage (62%) of hospitalization among pediatric patients, while rates among the other age groups within children showed little variation.

Statistics Canada has also released detailed information about Canadian COVID-19 cases as of September 13, 2020 which contains symptom information for 2,310 children. The first chart shows the breakdown of symptoms (with 1 or more present) from positive COVID-19 pediatric cases. The second chart shows the breakdown of symptoms where the positive case presented with only 1 symptom which occurred 25% of the cases with symptom information (571 children).

Adult and Pediatric - Underlying Medical Conditions for Hospitalizations:
The CDC also runs COVID-NET which tracks various information such as hospitalizations by age, characteristics of hospitalizations and underlying medical conditions. In the USA, the most prevalent medical condition for adults who were hospitalized are those with high blood pressure (hypertension), followed closely by obesity, then metabolic disease (which includes diabetes), and cardiovascular disease. You will notice that the top 4 conditions of this respiratory virus have impacts on the heart, blood, or cardiovascular system which are all interconnected. Most of the underlying conditions people have already heard about come from China where obesity is not as big of an issue as in North America. This really highlights that obesity will also put people at high risk, especially since someone who is obese may have multiple other underlying medical conditions putting them at even higher risk if they get infected. Those with chronic lung disease, renal disease, and asthma are also among the top conditions. Interesting that people with compromised immune systems are actually lower in prevalence to most other conditions, although this may be a factor if an exaggerated immune response is part of the problem of people who are hospitalized, may play in their favour. Looking at the pediatric underlying medical conditions show that the majority of hospitalized have no known conditions, followed closely again by obesity. Asthma has a bigger role with children vs adults, and many children are not old enough to develop some of the conditions that are more prevalent in adults which helps explain why they are very low.
