Undetected asymptomatic cases and their reduction due to screening across testing frequencies, assuming no vaccination. A shows undetected asymptomatic cases by test community incidence and organization testing frequency; B shows the percentage of asymptomatic cases detected via screening by test frequency. Number of undetected cases is shown for a range of incidence rates; percentages are constant across incidence rates and increase more quickly as test frequency increases. Default values were used for other input parameters
