  1. Infected individuals may or may not have viable virus and positive PCR test results are treated as true positives, indicating isolation
  2. Ag: antigen; ICER: incremental cost-effectiveness ratio; IgG: immunoglobulin G; PCR: polymerase chain reaction; QALY: quality-adjusted life year; ∆: difference
