Agent-based simulation model of a chikungunya epidemic. We assigned demographic variables to each human agent, consistent with census information. We also assigned households, schools, and workplaces to human agents (mobility model), consistent with census information. Each household, school, or workplace also has a mosquito population that can interact with human hosts (during school and work hours). We used a standard susceptible-exposed-infected-recovered (SEIR) model to represent virus infection in human agents. We used an SEI model to represent virus infection in the mosquito population.
