Conflicts of Interest during Contact Investigations: A Game-Theoretic Analysis

Figure 2

Example of state transitions within a small group, according to (6). Each arrow is labeled with a description of the transition. Each individual is represented as a circle, labeled with the state (𝑆—susceptible, 𝐸—exposed, 𝐼—infectious, 𝑅—diagnosed and visited by a disease control investigator, 𝑆^′—susceptible but has been visited by a disease control investigator, 𝐸^′—exposed, but has been visited by a disease control investigator, 𝑉—exposed, but protected by post-exposure prophylaxis). The individual who undergoes the next transition is shown as a gray circle. Many such paths are possible.
