Figure 4

Distribution of the number of African swine fever virus–infected premises connections through vehicle movements, South Korea, 2019. IP out-degree represents the number of other IPs to which an IP sent >1 vehicle; IP in-degree represents the number of other IPs from which an IP received >1 vehicle. With 1-day (A), 3-day (B), or 6-day (C) assumptions for the duration of vehicle infectiousness, only the movements made up to 20 days before an exit farm reported suspicion of ASFV infection and before an entry farm reported suspicion of infection were considered. In the boxplots, center horizontal lines represent medians, and box limits represent upper and lower quartiles. Upper and lower whiskers extend to the largest and smallest values within 1.5× interquartile ranges. The point represents an outlier. ASFV, African swine fever virus; IP, infected premises.
