Table 1. Parameters involved in the transmission model for MRSA ST398.

Parameters	Description	Value (unit)	References
λi	Proportion of susceptible individuals who acquires MRSA per unit of time
β 0	Per-contact transmission probability for MRSA non-ST398	0.13	[20]
ξ	Relative transmission risk for ST398 MRSA compared to non-ST398	0.17	[11]
β	Transmission probability for MRSA ST398	ξβ 0
µT	Clearance rate for transient carrier	0.94 (d−1)	[21]
µP *	Clearance rate for persistent carrier	0.057 (d−1)	[23]
δ	Probability of acquiring MRSA ST398 from contact with pigs	δ 0 = 0.1	[5]
Q	Probability of being a permanent carrier	Tested values: 0.05,0.1,0.2,0.35

^*Assuming clearance rate for persistent LA-MRSA carriage in humans is equivalent to that in pigs. This value is conservative since MRSA ST398 is adapted to pigs.
