Parameters for outbreak simulations

Parameter	MRSA	Influenza	Source
Mean duration of colonization (MRSA) or infection (influenza)	75 days	3 days	Kajita et al,13 van den Dool et al17
Baseline room-sharing probability of infection (day−1)	0.12	0.26*	Nerby et al,33 van den Dool et al17
Baseline HCW-sharing probability of infection (contact−1)	0.0169†	0.13*	McBryde et al,15 van den Dool et al17
Vaccine efficacy	NA	86%	Thomas et al34

*Based on estimating HCW contact as ‘casual’ contact, and room-sharing as ‘close’ contact.

†Based on single contact risk squared.

HCW, healthcare workers; MRSA, methicillin-resistant Staphylococcus aureus.
