Geographic Clustering of Leishmaniasis in Northeastern Brazil1
Figure 1. Satellite view of distribution of patients with disseminated leishmaniasis (DL; black circles) and patients with mucosal leishmaniasis (ML; red circles) in Corte de Pedra, Brazil, 1999–2003. Vertical line divides the region into inner (left) and coastal (right) areas of similar size. Total number of patients shown is smaller than the number of corresponding patients because of overlap of geographic coordinates for some patients. For details, see Materials and Methods. p = 0.00005, for data analyzed by using the Cuzick and Edwards test in Clusterseer version 2.2.4 (Terraseer Inc., Ann Arbor, MI, USA). The yellow mark indicates the health post.
