Table 1. Key model parameters, including symbol, description, and sample ranges used in the LHS sensitivity analysis.

Parameter	Description	LHS range, min/max
C	Mean number of contacts per host	4:12
ρ	Degree of randomness in the host contact network	NA
1/μ	Average duration of infection	3:10
1/σ	Average duration of immunity	10:30
β	Probability of transmission (to a completely susceptible host)	0.2:0.8
R	Probability of recombination per allele	0.01:0.1
τ	Probability of allelic mutation per allele	0.001:0.005
γ	Degree of cross-immunity	0.02:4
N	Number of immunodominant loci	2:4
P	Host population size	100:500

For the LHS analysis, we used a uniform probability distribution function for each range of parameter values. NA, not applicable; min/max, ratio of minimum to maximum values.
