COVID-19 Three Day Change Report

In my ongoing quest to present the Coronavirus data from the CDC and WHO in useful ways, I have created another set of report pages. There are to primary pages that show all countries with the percent of change in non-recovered cases in the past three days. Our previous reports provided a lot of information for deep analysis but it wasn’t so easy to make quick comparisons and to see how a state or country was progressing. This latest report connects to the same dataset but will let you see how the numbers have changed in the past three days across countries and states.

Click the following screen image to view the publish-to-web report. Just right-click a country to drill-through and view state/province three-day changes. The CDC and WHO provide state & province case data only for the United States, Canada and Australia.

I’ll update the GitHub repository and the template app with these additions as well.

Non-recovered cases are the number of confirmed cases less the number of recovered cases. The “Confirmed Cases” metric used in reports we see in most news programs and websites is the all-time accumulated total for a country or state. Attempts to report only the number of active cases has been inconsistent across geographies. This method to calculate the recovery rate seems most reliable at the country level but we don’t yet have consistent recovery numbers at the state and county level in the unified data set.

Roadtrip, Climbing Case Numbers and Public Perception

Having this information at our fingertips makes a huge difference. My wife and I are currently on an unplanned road trip attending to some urgent family business. In light of the outbreak, we are driving about 3,500 miles rather than flying. Driving through Oregon, Idaho, Utah, Arizona and New Mexico; it is apparent that the situation is perceived very differently in different areas. For example, the Navajo reservation is observing curfew and no one is allowed to be outside their homes under penalty of law. In New Mexico, absolutely everyone must wear a mask to go into a store. But in other places where we have traveled in the past two days, it is life as usual with little or no restrictions – even though the number of confirmed cases has risen by about fifteen percentage points in the past three days. Here in New Mexico, cases have increased by about 28% so we will be wearing our masks and cautiously practicing social distancing.

Countries with Improved COVID-19 Recovery Rates

Is there any good news in the COVID-19 Coronavirus data? Everyone is familiar with the tragic growing number cases and fatalities globally and in most countries that have high populations. However, several countries have increasing recovery rates. You can click here to view the new Power BI report shown in the image below.

The experts keep taking about looking for “the peak”, when the number of people recovering from infection increases faster than new cases. We’re not there yet but where is the recovery rate increasing? The “Recovery Rate (3 Day Change)” measure is the Recovery Rate (e.g. The number of confirmed cases divided by the number of recovered cases) from three days prior to the most recent report date. This report ranks countries by this measure.

On the left side are the countries highest ranked in improved recovery rates over the past three days (pictured as of April 10). The line chat on the right shows the top 20 countries with their trend of Recovery Rates over the past 30 days.

Among these are countries with small populations or those with a small number of confirmed COVID cases, so even a small number of recovered cases yields a high ratio. To remove some of these outliers, the report page only includes countries with 100 or more cases. Some could have had a high infect rate that has since slowed or it could be a lag in the available recovery date. This report uses the dataset from the main COVID-19 Daily Updates report but just focuses on recover rates.

By the time you read this, the top 15 countries by improved recovery rates may change. Right now, these countries have the highest increase in recovery rates. Why is this and what can we learn from these results?

I Need Your Questions about Power BI and Paginated Reports

For a new series of posts to include tutorials and “how to” demonstrations for Power BI, SQL Server Reporting Services (SSRS) and Paginated Reports, I need your help to know what questions are most compelling and top of mind.

Please scroll to the Comments section at the bottom of this post and help me create a list with your questions and suggested topics.

What questions do you have and what do you need to learn how to do?

Make suggestions and cast your votes on others’ ideas for video posts, demos and tutorials you would like to see. I will add these to a list and work through as many as I can. The following are some rough topic areas and ideas to get started:

Power BI Solution Questions:

  • Power Query techniques
  • Data modeling techniques
  • DAX calculation techniques
  • Visualization best practices
  • How to design a specific report feature
  • Of the many choices or approaches to address a business need, which is a recommended practice?

Paginated Reports & SSRS Questions:

  • How do Paginated Reports work in the Power BI cloud service?
  • How are Paginated Reports and SSRS licensed from Microsoft?
  • When should I use Power BI vs SSRS or Paginated Reports?
  • Navigating between different report types
