The project performed simulations for (1) daily testing (tests of only 50% of symptomatic population) and (2) daily testing + cluster interventions (ref.: daily testing + random testing) to estimate the trend for new infections and evaluate the efficiency of testing strategies
Note: Cluster interventions: For groups of 3 or more positive patients, identification and testing of primary and secondary contacts of positive patients

Cluster interventions require a significant increase in the number of tests performed, but are effective at restraining transmission.
Achieving equivalent positivity trends to cluster interventions would require random testing of 1% of the asymptomatic population. Cluster interventions are able to restrain infection growth with fewer tests.
