COVID19 COVID-19 - Useful Info & Daily Stats
(Global, Canada, and Ontario)

This page contains links to useful information and 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.  Those graphs are updated on a daily basis early morning each day.  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 sympoms 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.

Ontario Hospitalization and Testing Stats:

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.

Global:

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.

** Since testing is extremely restricted and cases are not being contact traced or tracked properly, stats related to daily cases below are no longer being updated and only available for historical reference. **

Canada, Ontario & Quebec:

**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.
