Fig. 4: The impact of unvaccinated-only screening corresponds to three distinct parameter regions.
Total number of infections with no screening (black) and weekly testing with 99% compliance (pink) are shown for a 25%, b 75%, and c 95% population vaccination rates. d Effective reproductive number over various population vaccination rates, where Reff = 1 is denoted by gray dashed line. The impacts of screening fall into three categories (see text) depending on whether vaccination rate falls into region I, II, or III, as annotated. \({R}_{0}^{{{\mbox{NPI}}}}\,=4\) and 35% rate of prior infection with baseline immunity parameters (Materials and Methods, Supplementary Table 2).
