Figure 2: Model projections for the time to epidemic in India (the time to reach a prevalence of 1000 cases), under different scenarios for the intensity of port-of-entry screening. The left half of the figure illustrates the effect, on epidemic timing, of screening symptomatic passengers alone; the right half illustrates the additional effect of diagnosing coronavirus disease-19 amongst asymptomatic passengers, assuming full screening of symptomatic passengers (infeasible, but illustrative). Solid lines show central estimates, whereas dashed lines span 95 per cent of simulated uncertainty intervals.
