Spatiotemporal clusters of hemorrhagic fever with renal syndrome in mainland China, during 2005–2012, detected using Kulldorff's spatiotemporal scan statistics^*.

<p>* Significant clusters with P<0.01; 1: Primary cluster; #2-9: Secondary clusters; E_Minor: Semiminor axis of ellipse; E_Major: Semimajor axis of ellipse; E_Angle: the angle between the horizontal line and the semimajor axis of the ellipse; E_Shape: E_Major: E_Minor; No. Counties: number of counties within clusters; No. Obs: number of observed cases; No. Exp: number of expected cases; LLR: log likelihood ratio; RR: relative risk for the cluster compared with the rest of the country.</p><p>Spatiotemporal clusters of hemorrhagic fever with renal syndrome in mainland China, during 2005–2012, detected using Kulldorff's spatiotemporal scan statistics^{<a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0003344#nt102" target="_blank">*</a>}.
