Figure. Sampling locations for 161 pet and 88 stray dogs along 2 transects that followed major roads leading north (squares) and southeast (triangles) from the Nipah virus encephalitis disease-epidemic areas in Bukit Pelanduk and Sepang, Malaysia. Color-coded squares and triangles refer to the transect interval where they were taken (light blue, 0–8 km; orange, 8–15 km; green, 15–20 km). The recognized disease-epidemic areas in pigs and humans are outlined by thick green lines. Sampling sites of Nipah virus antibody–positive dogs are indicated by stars (yellow, pet; blue, stray). Numbers in parentheses beside each transect indicate number antibody positive/number tested from each transect. Distances are in road kilometers; however, all antibody-positive animals were sampled within 5-km linear distances from the epidemic area.
