Table 2 Model parameters for SEIRS model

Parameter	Symbol	Value	Source
Latency period	1/ α	3 days	[30]
Reproductive number	R₀	5.7 individuals	[17]
Infectious period	1/ γ	10 days	[31]
Natural immunity duration	1/ δ	18 months	[32]
Infection fatality rate	σ	0.68%	[33]
Population birth rate	μ	1% annually	[34]
Population death rate	λ	0.9% annually	[35]
Fraction compliant	f	Variable
Protective efficacy	1-b	Variable
Transmission reduction	1-c	Variable

All parameters defining the ODE-based SEIRS model. In this analysis, the fraction compliant, protective efficacy against infection, and reduction in transmission are treated as independent variables
