How infection and behavior influence each other (IMAGE)
Caption
The diagram shows how people’s decisions—like going to work or staying home—affect how a disease spreads, and how the spread of the disease, in turn, influences those decisions.
At the top, it shows that people with higher or lower socioeconomic status (SES) behave differently depending on how severe the outbreak is. For example, in a low-infection situation, people are more likely to go to work, while in a high-infection scenario, more people stay home to avoid getting sick.
At the bottom, we see how the disease moves through a network of people. In three snapshots, we watch how infected individuals pass the disease to others. Some people choose to quarantine (shown with dashed green circles), which means they temporarily disconnect from others and stop the spread. After a while, infected people either recover or are removed from the system. Shapes represent different SES groups, and colors show who is infected. Solid lines mean people are in contact and can spread the disease; dashed lines mean they’re not in contact.
The curved arrows in the diagram show how behavior (like deciding to quarantine) and disease spread are linked together—each influences the other in a constantly changing process.
