Intervention scenarios for controlling transmission within university settings.

Scenario Transmission probability per contact household/other per day Mean no. of random contacts (SD = 1) Mean no. of within-course contacts (SD = 4) Max living circle size % transmission reduction due to self-isolation within/between groups Asymptomatic testing
