Before revision:  In this paper we propose a novel approach based on periodic SARS-CoV 2 antibody testing to reduce the risk of contagious within the working space, and evaluate it using stochastic simulations of the health evolution of the workforce. Our simulations indicate that the proper use of testing and quarantine of workers suspected of being infected can greatly reduce the number of infections while improving the productivity of the companyin the long run.
After revision:  In this paper , we present a novel safety protocol based on rapid antibody testing (ABT). Using discrete event simulation, we evaluated its performance on the cumulative number of infected workers, effective reproductive number (R_e), and active work force within a company. Using a synthetic experiment, we showed that ABT twice a week (ABT 3) performed the best, detecting 5.7
