Table 1.

Table of variables. Summary of the variables used in the experiments. The cumulative probability distribution is reported as {p1,p2,pn}, where pi is the probability that i is the last day of latency or of infectiousness, and a measles case will change state within n days

Base case scenario
Variables Base case value Source
Population of Virginia 7,688,059 Synthetic populations [13]
Infected individuals at day 0 1 (5–17 years of age) Assumed
Proportion vaccinated 91.5% Calibrated using VDH school immunization data [26] and state-level immunization rate [27]
Transmissibility 0.5 Calibrated to generate an outbreak size of 650 [28]
Simulation duration 365 days Assumed
Home isolation compliance 90% [25]
CDF of the latency period distribution {0, 0, 0, 0, 0, 0.1, 0.2, 0.6, 1} [25]
CDF of the infectious period distribution {0, 0,0, 0, 0, 0, 0.3, 0.7,1} [25]
