Detecting clusters and trends of childhood diarrhea is important to designing SaTScan Spatial Statistical Analysis. PLoS ONE 10 effective interventions. Therefore, this study aimed to investigate spatiotemporal clustering (12): e0144690. doi:10.1371/journal.pone.0144690 and seasonal variability of childhood diarrhea in northwest Ethiopia. Editor: Agricola Odoi, University of South Africa (South Africa) and University of Tennessee (USA), UNITED STATES Methods Received: April 18, 2015 Retrospective record review of childhood diarrhea was conducted using quarterly reported Accepted: November 22, 2015 data to the district health office for the seven years period beginning July 1, 2007. Thirty Published: December 21, 2015 three districts were included and geo-coded in this study. Spatial, temporal and space-time scan spatial statistics were employed to identify clusters of childhood diarrhea.
