Table 1

Uniform distributions for each variable used in simulations to assess the cost-effectiveness of vaccination against West Nile virus (WNV)*

Variable Lower limit Baseline Upper limit
Probability of infection 0.012 0.016 0.02
Probability of symptomatic illness 0.15 0.20 0.25
Probability of symptomatic illness after vaccination† 0.03 0.04 0.05
Probability of neuroinvasive disease, given symptoms 0.027 0.036 0.045
Probability of death, given neuroinvasive disease 0.07 0.09 0.11
Probability of disability, given neuroinvasive disease 0.26 0.35 0.44
Cost of neuroinvasive disease $20,625 $27,500 $34,375
Cost of death (direct and indirect financial losses) $150,000 $200,000 $250,000
Cost of lifelong disability $158,000 $210,000 $263,000
Cost of uncomplicated WNV febrile illness $750 $1,000 $1,250
Cost of vaccination $75 $100 $125

*Upper and lower limits are calculated as ±25% of the baseline values and rounded up.
†Baseline vaccine effectiveness is assumed to be 80%.
