What should be compliance rate to twice per week mass-testing for effective COVID-19 control in universities?
Some universities have adopted twice-per week mass test for SARS-CoV-2, followed by trace and test. We looked at what combinations of compliance to: reduced contact rate, asymptomatic testing, and face-mask-use/ 6ft distancing, are necessary to prevent deaths. Preliminary results from applying previously described SEIR model . WebApp GitHub Model
- Ten initial infections ( representing infections that went undetected at initial testing assuming test sensitivity is around 70% (for asymptomatic) and 90% (for symptomatic)
- Five infections per week enter the university population every week from outside- e.g., through travel, contact with people in the community, and surrounding communities.
- About 50% of the university population – constituting those with at least one of F2F classes, on-campus office and lab, and on-campus housing – are required to get tested twice per week

Simulation tool for COVID-19 control in NY (v2)
Version 2 of simulation
V2 is released. This is an interactive simulation tool for evaluating combinations of contact reduction, contact tracing and testing, and universal testing needed for efficient phased reopening . This version allows evaluations of multiple alternative combinations, flexibility to change units costs, and flexibility in setting analytic time-period.
