- Since the confirmation of the first coronavirus case in the United States, more than half a million people have tested positive.
- The Coronavirus COVID-19 Global Cases map makes it possible to track the COVID-19 outbreak in the United States.
- The logarithmic scale is ideal for measuring the exponential growth and helping us see the bigger picture of the coronavirus outbreak.
It is now close to three months passing since the confirmation of the first COVID-19 infection in the United States. Since that day, on the 21st of January, more than half a million people have tested positive for the coronavirus in the United States alone. Staying at home, closing schools, universities, and many nonessential premises seem to be the best solutions for many Americans, and the rest of the world.
However, we are still not sure how long such measures will last and when will the effects of the coronavirus subside. The U.S. is currently (and unfortunately) at the top when it comes to the number of death from coronavirus throughout the world. In case you want to track those numbers yourself, there is now a way you can do that (with close to real-time accuracy).
The Coronavirus COVID-19 Global Cases Map
A large portion of the cases comes from the city of New York, which is counting almost 200,000 cases, with over 10,000 deaths. Why New York of all the places? Well, it might be useful to understand how the rate of infection changes daily and how different states compare. For that reason, The Center for Systems Science and Engineering at Johns Hopkins University developed The Coronavirus COVID-19 Global Cases map.
The Coronavirus map (both global and the United States) enables us to track the spread of the novel coronavirus in real-time (or as close to real-time as possible), with constant updates and zoom functions that work on state and country level. There was also a county-level option until recently, but due to the maintaining accuracy of the date, it was eventually canceled.
The United States Centers for Disease Control and Prevention, and various city authorities, among others, are responsible for providing the data. The map displays the number of confirmed cases, death, recoveries, as well as the total number of tests conducted (which is currently close to 3 million). On the United States map, you can also enquire about the top counties by the number of deaths and top confirmed cases.
It Is Not Just About The Daily Counts
It is also about the "big picture." If we were to understand the outbreak locations in The United States and compare them to each other, it is important to take into account the rate of change and how it changer over the days in a particular location. That is why many sources use a logarithmic scale (because it is very useful for measuring the rate of change), which helps display numerical data over a wide range of values in a compact fashion.
Exponential growth curves are usually displayed on a logarithmic scale because they help us see the bigger picture. Simply put, as coronavirus cases increase, the curve moves upwards. As the cases start to decline in their frequency, the line shapes towards a horizontal position, indicating that the outbreak is beginning to slow down. It is useful because it shows us the point in time where exponential growth subsides and enabling us to see when exactly our hand washing and social distancing made a difference.
