Let’s walk through the map. First, click the link below.
Thanks to the internet, we are able to follow in real-time the progression of coronavirus (COVID-19) across the globe with the use of online maps.
My personal favorite was created by John Hopkins University and Medicine. There are many other maps similar to this, but I must give a word of caution because they may contain incorrect information or malware that could harm your computer.
So let’s navigate the map together. Click here to view this map. If you ever get lost and want to get back to the map, you can click on this link again to open another map. Please note that the map design continuously changes.
From the top left, you can see the John Hopkins University and Medicine logo. Click on the logo to be redirected to the university’s homepage for more coronavirus information. Moving your cursor to the right, you can click on “Map Information” for details on what this map represents, “Map FAQ” to view answers for frequently asked questions about the map, or the home picture to be redirected to the University’s homepage.
Below this blue line, you can see the title, “Coronavirus COVID-19 Global Cases by the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University (JHU).”
Then move your cursor to the top-right corner of each box for a small circle with 4 diagonal arrows. Click on this circle of arrows to zoom-in on the box (then move your cursor to the top right of the box and click on the circle of arrows to zoom back out to the original map).
From the top left, you can see the number of “Total Confirmed” which refers to the number of “confirmed” coronavirus cases based on medical testing from a licensed medical professional. Below this, you can see another box labeled “Confirmed Cases by Country/Region/Sovereignty.” This box breaks down the bigger number of “Total Confirmed” by individual countries, regions, or territories. With your cursor on this box, scroll down to view how many total confirmed cases are within each of these labeled areas. You may also click on the right or left triangles below this box to view the “Confirmed Cases by US County”
In the middle of the webpage is the map. To move around the map, bring your cursor on top of the map, click and hold your mouse, then move your mouse in order to move the map. You can zoom in and out of the map by bringing your cursor to the top of the map and scroll with your mouse. On the top right of the map, you can see a box with pictures of a ribbon, lines, and 4 squares.
You can click on the ribbon to open a drop down menu labeled “Bookmarks.” You can scroll down the list and click on any of the countries to redirect yourself to that specific country. If you click on the picture with the lines, you will open a drop down menu labeled “Legend.” This drop down menu will show you what each size of red circle on the map equals in terms of amount of confirmed cases. The final picture with 4 squares will open a dropdown menu labeled “Basemaps.” Clicking on any of the maps on the dropdown menu will change the type of map you will see in the larger map. On the bottom left corner of the map, you can see “Cumulative Confirmed Cases” and “Active Cases.” Click on “Active Cases” to see orange circles, which represent people who actively show symptoms of the disease, and click on “Cumulative Confirmed Cases” to see red circles that represent the total amount of confirmed cases.
The placement of the circle represents where the disease is located and the size represents how many cases there are. The bigger the circle, the more cases there are, and the smaller the circle, the less cases there are. You can click on any of these circles to learn more about the number of confirmed cases, deaths, recovered individuals, and active cases in that area.
From the top right of the webpage, you can see the “Total Deaths” in white text. Scroll down this box to learn how many people died from coronavirus by area. On the right side of this box, you can see the “Total Recovered” in green text. Scroll down to learn how many people recovered from coronavirus by area.
On the lower right of the webpage, you can see a graph with orange, yellow, and green lines. Move your cursor to the upper right corner to pull up a circle with 4 diagonal arrows. Click on this circle to zoom-in on the graph.
If you look at the bottom of the graph, you can follow the progression of the disease starting from Jan 20th, 2020. At the left of the graph, you can see increasing numbers representing the total number of cases (1k = 1,000. 10k = 10,000. 100k = 100,000, and so on). The orange line represents the total number of confirmed cases globally. You can click on “Daily increase” to see a bar graph of the total number of new confirmed cases that day. To interpret this graph, you want the orange bars to go down (which means the disease is slowing down its spread). Move your cursor to the top right of the zoomed-in box to zoom-out back to the original map.
This coronavirus map will keep you informed on the progression of this disease all across the globe. Give it a try.
