Model setting for different interventions.

Intervention	Description in the model setting
Mask wearing	A person was regarded as touching the outer surface of the mask if they touched their own nose and mouth.
Reduction on surface touch	Randomly reduced the touches on public and private surfaces.
Changes in virus transfer rates between hands and surfaces	The transfer rate of the virus between hands and surfaces during each touch (including mucous membranes).
Disinfection frequency of a specific surface	The time for surface disinfection would be determined based on disinfection frequency. The virus on disinfected surfaces would be removed according to disinfection efficiency.
Disinfection efficiency	99.99% of virus was considered to be removed if a surface/hand is disinfected/sanitized (Pickering et al., 2010).
Disinfection of the surface made by the same material	Disinfect all surfaces made by the same material in the restaurant.
