As the Coronavirus disease (COVID-19) situation unfolds in Canada and around the world, news sites, public health agencies, universities and other organizations are publishing charts and graphs to explain data in easy to understand ways such as the flattening the curve model and the spread of the virus. Unfortunately, people with print disabilities or individuals with slower internet connections are generally left out of the loop since these images are inaccessible to assistive technologies or images cannot load properly due to a lack of bandwidth. NNELS believes that this information should be accessible to everyone. In order to fill this gap, we are providing this information in alternative accessible formats such as text descriptions and use of sonification tools by producing some key charts/graphs and linking to other resources with accessible information. Sonification refers to the use of sound other than speech to convey information such as the height of a bar or the curve of a line. While we will primarily be focusing on data relevant to Canada, some information may be helpful to international readers.
If you have any issues accessing the data or find any errors, please don't hesitate to contact us. You may wish to bookmark this page as it will be updated often with new information.

When exploring this page, you will find contextual information followed by a detailed text description. Below the description are links to the same data available in additional formats.
In order to access charts and graphs produced by NNELS, you will need access to Google Chrome, and have the SAS Accelerator extension.
Once the SAS accelerator is installed, select the sonification link. A new page will load displaying an optimized image of the chart/graph for low vision users, generated by SAS Accelerator, along with an "Accelerate" button. When you activate the button, a graph view will load which allows you to now explore the graph auditorily. Press 'h' to obtain a list of keyboard commands. You can also tab to the "Settings" button to adjust verbosity and sound options. If there are issues with navigating the graph or the settings menu, please check to see if your screen reader's browse mode or its equivalent is turned off. Further documentation can be found on the SAS website.
For even more sonifications of data such as charts and maps, you may wish to check out the COVID-19 by the Numbers page from SAS.
Flattening the curve refers to the concept that if everyone becomes ill around the same time, the healthcare system will be quickly overwhelmed and will unable to treat patients in need of care. If public health strategies are taken to reduce the spread of infection on any given day, hospitals will have the capacity to care for people who are sick.
Note that this graph is not country specific and will not change since there is no dynamic information.
A graph showing one line, running horizontally through the middle which represents the Health Care System Capacity, and two curves, one representing the cases without protective measures, and the other, representing Cases with protective measures, (the flattened curve). The Y-axis is labelled as "Daily number of cases and the "X-axis, is labeled as "Time since outbreak". There are no numbers on either axis.
The curve representing "Cases without protective measures" starts at the bottom left corner and steeply rises past the "Capacity of the healthcare" line to a sharp curve at the top of the graph where it then steeply drops back down to the bottom. This line is symmetrical and is in the shape of a triangle with a rounded peak. Note that as this curve descends to the right side, it intersects with the "Capacity of the healthcare" line and the line representing "Cases with protective measures" just before the curve begins to flatten. The line representing "cases with protective measures" starts at the bottom left corner, gradually increases at first, before rising slightly more steeply, where it stays just below the "capacity of the healthcare line", and flattens out, before it gradually goes back down to the bottom. This curve is shaped like a small hill or an arch that rises and falls gradually and equally on both sides.

Data is based on 79,793 reported cases in Canada as of June 1, 2020, 11:00 AM EDT.
***Important Note*** Due to lag times in data being reported, the graph shows an incomplete picture. According to the Government of Canada, the number of cases is still increasing and has not peaked.
If date of illness onset was not available, the earliest of the following dates was used as an estimate in the following order: Specimen Collection Date, and Laboratory Testing Date.
A bar graph with vertical bars depicting the COVID-19 cases in Canada by date of illness onset. The X-axis is labelled as "Date of Illness onset" (from January 15, 2020 to May 31, 2020) and the Y-axis is labeled as "Number of Reported Cases" which range from 0 to 1,800, in increments of 200. The shape of the bar graph starts out flat with a few very short bars at first (from January 15 to the end of February), then gradually increases in height. The bars steeply increase (with occasional drops between days),peak on April 13 with nearly 2000 cases, then decrease, (in a general "v" shape). The graph’s background is partially shaded from May 18 until May 31, where the graph ends. This indicates a period of lag time where, according to the Government of Canada, cases may have occurred but have not yet been reported nationally. Visually, the dates on the X-axis are shown for every three days, but there are bars for each day. Full data can be found on this page: Epidemic Curve: COVID-19 cases in Canada by date of illness onset - Table.

Data is based on 87,784 reported cases in Canada as of June 1, 2020, 11:00 AM EDT.
Note that due to lag times in data being reported, numbers should be used to observe trends and should not be taken as absolute.
A graph with horizontal bars depicting the Age and gender distribution of COVID-19 cases. The Y-axis is labelled as "Age group (years)", and the X-axis is labelled as "Number of cases with case reports", which range from 0 to 16,000 in increments of 2000. At the end of each bar, is the "Number of cases with case reports", and also shown as a percentage.
The group with the least number of case reports is those who are 19 or younger (6.33%). The bars increase steadily through ages 20-29; 30-39; 40-49; and 50-59 which peaks at 15.47%. The bars decrease through ages 60-69 and 70-79 (dropping to 7.76%, before sharply rising in the 80+ age group, at 18.74%.
Each bar also shows the breakdown between the number of cases for males and females, represented by dark blue and light blue colours, respectively. In all cases, the length of the dark blue (males) portion of the bar, is less than half the length of the light blue section, indicating that there are more cases for females, compared to males, in all age groups.
Complete data can be read in this table: Age distribution of COVID-19 cases in Canada - Table.
Data is based on 91,340 cases in Canada as of June 1, 2020, 11:00 AM EDT.
Note: The total number includes publicly reported confirmed and probable cases. Due to lag times in data being reported, numbers should be used to observe trends and should not be taken as absolute.
A map of Canada shows the number of confirmed cases by province, using progressively darker shades of blue for provinces with higher concentrations of cases. Quebec is dark navy blue, indicating (according to the legend) that it has more than 30,000 cases. Ontario is a lighter shade, indicating that it has between 20,001 and 30,000 cases. On the legend, the next lighter shade indicates between 10,001 and 20,000 cases; no provinces have this colour/number. Alberta and British Columbia are the next lighter shade, indicating between 2,001 and 10,000 cases; then, Nova Scotia, with 1,001 to 2000 cases; then at the lightest shade of blue, indicating between 1 and 1000 cases, are the Yukon, the Northwest Territories, Saskatchewan, Manitoba, Newfoundland, New Brunswick, and Prince Edward Island.

On April 9th, the Government of Canada released a technical document: COVID-19 in Canada: Using data and modelling to inform public health action." This PDF document, available for download (download COVID-19 in Canada: Using data and modelling to inform public health action), includes a number of graphs and figures.
Text description based on an interactive graph shared in a CBC article on March 27, 2020. Read the article.
An interactive line chart depicting the rate of spread of COVID-19 cases by day per location. To show where British Columbia is on the curve, additional curves are drawn to help readers compare other districts. The X-axis is labelled as "Days", beginning with "Day 1" and ending at "Day 15." The Y-axis is labelled as "Total COVID-19 cases announced by different jurisdiction with Day 1 marked by the first time it had more than 100 positives." The values on the Y-axis go up exponentially and starts at "100" for day 1. The remaining values on the Y-axis are "1000" and "10,000." There are twenty faint lines extending across the chart, horizontally, equally spaced, with the first and the eleventh lines coming from where "100" and "1000" are labelled. These lines are to help readers identify values by looking at where the curves intersect.
Visually, the days on the X-axis are shown for only the odd days but the values for the number of cases are available for each day. They are hidden until the user interacts with the chart. When you hover over a dot on the graph, it will tell you the day number, the place, and the number of cases.
Each place is represented by a dotted line. Every line begins at the bottom left corner of the graph and then rises to the upper right side. Specific trends along with certain values are written out in this description and provided as a table. However, since no data was provided, we only share the values that can be seen in the chart.
British Columbia begins with a steep line which rises to day 3 with 231 cases. From Day 3, the slope of the line increases slightly with a shallow curve to day 6 with 424 cases. From day 6, the curve steadily rises with a few jags to day 9 with 617 cases. From day 9, the line continues to slope gently upwards, almost plateauing and with a few small spikes, all the way to Day 15 with 970 cases.
Alberta starts with a steep incline to day 4 with 207 cases. from day 4 the line continues with a very slight slope upwards to day 10 with 486 cases. From day 10, it flattens out but still has a very slight upwards curve to day 13 which has 661 cases
Ontario Starts out with a very steep line to day 3 with 177 cases. From day 3, the line continues to rise with less of a steep incline to day 10 with 503 cases. From day 10, the line continues with a wide curve upwards all the way to day 15 with 1144 cases.
Washington State begins with a steep line with a slight curve to day 6 with 457 cases. From day 6 the line continues with a gentle curve upwards to day 14 which has 1500 cases. From day 14 to day 15, there is a slight spike which ends with 1800 cases.
United Kingdom starts out with a steep curve to day 6 with 459 cases. The line flattens out at day 7 also with 459 cases. From day 7 to day 12 which has 2600 cases, the line continues to rise with few very minor jags. From day 12, the line continues upwards with a very slight slope to day 13 with 2700 cases. From day 13, it becomes an incredibly steep curve to day 15 with 5100 cases.
Switzerland starts out with a steep curve to day 4 with 337 cases. From day 4 to day 5 which has 374 cases, it continues with a shallow curve. From day 5 the line changes to a steep curve to day 7 with 652 cases. The line flattens out since days 7 and 8 have the same number of cases. From day 8 the line curves up drastically with a few minor bumps to day 11 with 2200 cases. The line plateaus at day 12 with 2200 cases as well. From day 12 it continues as a steep curve with a few bumps to day 15 with 4100 cases.
France begins with a slight curve to day 4 with 204 cases. From day 4 it becomes a very steep curve with a few bumps along the way to day 15 with 6700 cases.
Italy has the highest starting point from day 1 with 155 cases. From day 1 to day 15, the line steeply rises, going straight up with a few bumps along the way ending with a cumulative number of 7400 cases.
Spain begins with an incredibly steep curve with slight bumps, to day 10 with 2300 cases. From day 10 to day 11 with 5200 cases, the line continues as a straight line that is nearly pointing straight up with a slight bend. From day 11, it becomes a steep upwards curve to day 15 with 11700 cases. The curve is not as drastically steep compared to Days 10 and 11.
