From: The impact of phased university reopenings on mitigating the spread of COVID-19: a modeling study
Projected active infections (daily) throughout the semester for each intervention. Expected number of active infections throughout the semester under three interventions: No phased reopening or pre-arrival testing (solid red line), no phased reopening with pre-arrival testing (dashed blue line), phased reopening with pre-arrival testing (dotted green line). Top left panel: effective mitigation strategies throughout semester (Rt = 1.5). Top right panel: moderately effective mitigation strategies throughout the semester (Rt = 2.5). Bottom left panel: ineffective mitigation strategies throughout the semester (Rt = 3.5). Bottom right panel: improving mitigation strategies throughout the semester (R0 = 3.5, R1 = 2.5, and Rt = 1.5 for months t ≥ 2)
