Fig. 1: Progress in genomic surveillance over the course of the outbreak.

From: Integration of genomic sequencing into the response to the Ebola virus outbreak in Nord Kivu, Democratic Republic of the Congo

a, Total numbers of sequenced (orange) and unsequenced (gray) laboratory-confirmed cases of EVD as reported in WHO (World Health Organization) situation reports. b, Correlation between the numbers of laboratory-confirmed and sequenced cases reported in individual health zones. c, Time lags between sample collection and release of phylogenetic analyses. In this figure, each row represents a sample. The x-axis position of a colored dot represents the date when a specific action occurred, and the color represents the action. Thus each row shows the amount of time that passed between different events for a single sequenced sample. Vertical lines represent events that occurred for a large proportion of samples; the dashed black lines represent when WHO declared that the outbreak started and ended. d,e, Kernel density estimates of lag times between sample collection and sequencing (orange), between sequencing and private release of the data (teal) and between sequencing and public release of the data (purple), before September 2019 (d) and after switching to privately released Nextstrain Narrative situation reports in September 2019 (e).
