We've created an agent based model of the transmission of Norovirus on a cruise ship. This agent based model was defined in Netlogo. A cruise ship environment was created with several different compartments - cabin, dining/common area, and pool deck. Agents were divided into workers and passengers, who had different daily schedules of commuting through the common areas. Infection spread was modeled by a probability of spreading the virus to another agent upon contact, represented in Netlogo as sharing the same patch as an infected agent. Illness was modeled with an incubation period following initial infection, an infectious period where agents can spread the virus, and a symptomatic period where agents confine themselves to their cabin. Total infected agents over the duration of the cruise can be monitored.
