Measles is a highly contagious viral illness that was declared eliminated from the United States in 2000 after decades of focused vaccination campaigns. However, pockets of measles-susceptible individuals exist across the United States that are at high risk for a measles outbreak should the virus be imported. In early 2014, an Amish individual traveled to the Philippines for aid work and returned to the largely unvaccinated and susceptible Ohio Amish community infected with the measles virus. The resultant outbreak was the largest measles outbreak in the United States in 20 years. The Ohio Department of Health quickly set a mass vaccination campaign into motion with the goal of immunizing susceptible Amish individuals and stopping the virus in its tracks. Here we develop a mathematical model of the measles outbreak in Knox County, Ohio, using a susceptible-exposed-infectious-recovered (SEIR) model implemented with the stochastic Gillespie algorithm. Using this model, we investigate the effectiveness of the public health vaccination campaign. Model results suggest higher probabilities of worse outcomes in the form of more cases and longer outbreaks when vaccination is removed or delayed, suggesting the positive utility of vaccination as a public health intervention in the Knox County Amish community.
