How to Track the Spread of Viruses Using GIS

By: GIS Geography · Last Updated: March 20, 2020

Monitoring Disease Outbreak Around the World

Everyday, communities are at risk of transmissible diseases and growing epidemics like COVID-19.

But how do we keep track of the spread of viruses?

We use GIS and real-time dashboards to track viruses, disease and global pandemics. In fact, the whole field of GIS started by mapping a Cholera outbreak in London, England back in 1854.

So, let’s take a look at some examples of GIS in the field of epidemiology.

Coronavirus COVID-19 Map at Johns Hopkins University

One of the best examples for disease tracking is from the Coronavirus COVID-19 Dashboard by the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University.

The COVID-19 virus began in Wuhan, China. Over time, it has quickly spread to other parts of the world. For example, the virus spread rapidly to Italy, South Korea and the United States.

As global cases rose, the Coronavirus COVID-19 became a global pandemic at the start of 2020. Throughout the Coronavirus COVID-19 global pandemic, the most complete picture of the outbreak came from Johns Hopkins University built using the Esri Operational Dashboard.

For example, it tracks the following:

  • Total confirmed cases of Coronavirus COVID-19
  • The number of total deaths and recovered from the virus
  • A proportional symbol map with geographic centroids

Real time disease map from HealthMap

One of the most reliable sources for real-time disease information is HealthMap. HealthMap brings real-time information on an hourly basis from thousands of sources.

All this information results in a real time disease map with over 90% accuracy. By using it, you can find out what health issues are happening where. Because you can see points as proportional symbols, you can better understand location patterns and the risk of spreading.

For example, you can collect:

  • Disease type
  • Location name
  • Number of cases

Boston’s Children’s Hospital founded HealthMap in 2006. A team software engineers, researchers and epidemiologists developed it to map out global disease outbreaks.

Tracking Disease Outbreak

These real time disease maps assist in recognizing the spread of epidemics.

They are accessible to travelers, citizens and decision-makers with timely information.

This can help countries prepare and fight global pandemics like Coronavirus COVID-19.
