COVID-19 Pandemic

• Track the four disease stages of a person in an epidemic

Use the model below to explore the progress of an epidemic. Set up the model, click the Watch a Person button to randomly inspect one person, then click Run a day repeatedly to track the four stages of one person. Can you always predict how long it takes for the person to get infected? Try several people.

• Collect data to explore the impacts of different factors on an epidemic

How do human-human and human-virus interactions lead to rapid disease spread? Use the model below to explore infectious disease outbreaks by looking into multiple factors and outputs. Open an online data sheet (you will be asked to make a copy of the datasheet). 

Procedures:

1. Set up and run the model at default settings. 

2. Explore how each of the following factors affects the Max daily cases and outbreak duration (days under the model speed bar). Retrieve the initial setting using the Default Settings button.

   • Population density 

   • Transmission Rate

   • Incubation period

   • Mobility

3. Can you explain these results? See the model rules in Model Info if needed.
