From: Quarantine for pandemic influenza control at the borders of small island nations
Performance of quarantine combined with rapid diagnostic testing. r 1(t) is the probability of releasing infectious individuals following the quarantine of length t days. Se = sensitivity of the rapid diagnostic test; Sp = specificity of the rapid diagnostic test; p = prevalence at the source community. Among infected individuals, those testing negative after quarantine of length t (i.e., p(1-Se)r 1(t)) are released into the community. Among uninfected individuals, those testing negative (i.e., (1-p)Sp) are released.
