Syndromic Surveillance for Local Outbreaks of Lower-Respiratory Infections: Would It Work?	2010-04-29		.txt	text/plain	4787	244	49	We evaluated how many LRI-clusters were detected in 1999–2006 and assessed likely causes for the cluster-signals by looking for significantly higher proportions of specific hospital discharge diagnoses (e.g. Legionnaires disease) and overlap with regional influenza elevations. Furthermore, since comparatively few new clusters per year were observed that would prompt investigation, syndromic hospital-surveillance could be a valuable tool for detection of local LRI-outbreaks. Geographic analysis methods -such as space-time scan statistics -may further increase the sensitivity of syndromic surveillance for detection of local outbreaks or of regional differences in regular seasonal epidemic diseases [2, 6] . The objective of this study was to evaluate to what extent syndromic surveillance detects local outbreaks of lower-respiratory infections (LRIs) without swamping true signals by false alarms. Of these, 6 belonged to influenza and/ or RSV related clusters (Figure 2a When repeating the weekly analyses with restricted time or spatial windows, both Legionnaires' disease outbreaks were still detected with the same timeliness.	./cache/cord-323433-9km824uh.txt	./txt/cord-323433-9km824uh.txt
