During these dramatic weeks of COVID-19 pandemic, my thoughts go to all people and families that are suffering beacause of the disease. Also, I think we should really thank all healthcare professionals that are currently fighting against the virus.

Today’s Covid-19 Data

These visualizations are built on the top of the daily COVID-19 data obtained from John Hopkins University, and plotted using the Covid19CountsPlot R library (https://github.com/dami82/Covid19CasesPlot). Briefly, instead of visualizing cumulative data, here I am showing day-by-day numbers. The goal is trying to understand when selected countries (or US States) of interest are reaching an apex or a plateau. Also, I hope to gain insights about time relationships/gaps between number of new cases and COVID-19 related deaths.

Europe and US

Figure 1. xy-plots showing the number of new daily COVID-19 cases (orange points, left y-axis) and number of daily deaths due to COVID-19 (blue points, right y-axis) with respect to time in a set of Countries of interest. Trendlines were computed by LOESS. The latest daily number of new cases and the latest daily death toll are reported. Data provided by John Hopkins University. Note: U.S. plot y-axis on a different scale.

Scandinavia

  • Denmark: 5.8M people, density=137/km2; largest city: Copenhagen, population=794K

  • Sweden: 10M people, density=23/km2; largest city: Stockholm, population=970K

  • Finland: 5.5M people, density=16/km2; largest city: Helsinki, population=650K

  • Norway: 5.4M people, density=14/km2; largest city: Oslo, population=693K

Trendlines were computed by LOESS. The latest daily number of new cases and the latest daily death toll are reported. Data provided by John Hopkins University. Note: Sweden did not enforce a lockdown during the COVID emergency.

US States

Top-20 US States by cumulative number of confirmed cases

Trendlines were computed by LOESS. The latest daily number of new cases and the latest daily death toll are reported. Data provided by John Hopkins University. Note: Plot have y-axes on independent scales.

US Counties

Selected US Counties: Los Angeles (CA), Middlesex (MA), Cook (IN), Marion (IN), Miami-Dade (FL), Wayne (MI), Fairfax (VA), and Philadelphia (PA).

Trendlines were computed by LOESS. The latest daily number of new cases and the latest daily death toll are reported. Data provided by John Hopkins University.
