Table 2 Values of the effective reproduction number identified in the 3 cross-contamination scenarios in a large university campus in Belgium during the first COVID-19 wave. The coupling index κ/β quantifies the importance of exogenous contamination in the university population; the population ratio corresponds to a coupling with the Belgian population (A) or with a regional population (B-C). The university population is nU = 30,000 individuals
