SARS-CoV-2 export risk from Louisiana

(A) Estimated number of location transitions inferred by phylogeographic analysis from New Orleans (left) and Shreveport (right). On the right of each graph the number of sequences in the dataset belonging to clade 20C and the Louisiana clade is shown. The strength of a connection between a particular location and New Orleans/Shreveport is relative to the difference between the number of location transitions and the number of sequences in clade 20C.

(B) Estimated number of infected travelers from New Orleans per week. The number of infected travelers was estimated based on local incidence and the total number of travelers between New Orleans and the destination.

(C) Percentage of import risk in the lower 48 U.S. states that can be attributed to New Orleans in the four epidemiological weeks after Mardi Gras. Import risk was estimated based on the number of infectious travelers relative to the population size and the total number of travelers at the origin (see Figure S10 for more details). Inset shows local relative import risk from New Orleans within Louisiana.
