2. Figure EVD spread across Guinea, Liberia, and Sierra Leona
Contour plot of the predicted week delay from the trend surface model with a polynominal order of six (A), speed and velocity of EVD spread by district (B), and average speed of EVD spread (dots) and confirmed cases of EVD by week by country (C). The inset map shows the Western Area Urban and Western Area Rural districts of Sierra Leone. The square root was taken for scaling purposes and the angle of the arrowhead represents the direction of spread and the size of the arrowhead is proportional to the square root speed in km per week (B). EVD=Ebola virus disease.
