Levels of minimum efforts of intervention strategies needed to control the spread of severe acute respiratory syndrome coronavirus 2, (i.e. reducing the reproductive number to <1), during the 2019 novel coronavirus disease outbreak in China. Strategies considered were quarantine of infected persons and persons who had contact with them (x-axis) and population-level efforts to reduce overall contact rates (y-axis). Percentages denote the percentages of transmissions driven by infected persons

Figure 6. Levels of minimum efforts of intervention strategies needed to control the spread of severe acute respiratory syndrome coronavirus 2, (i.e. reducing the reproductive number to <1), during the coronavirus disease outbreak in China. Strategies considered were quarantine of infected persons and persons who had contact with them (x-axis) and population-level efforts to reduce overall contact rates (y-axis). Percentages denote the percentages of transmissions driven by infected persons that were not detected by surveillance as a result of asymptomatic infection, mild-to-moderate illness or low surveillance intensity.
