Although there was a remarkable temporal correspondence surveillance peaks, most timely involved use systems in which personnel with existing close ties to public health programmes perceived importance providing information despite workload constraints associated an During investigation, could be easily linked laboratory data, were flexible adding new variables, and demonstrated low baseline variability useful. Geographically fixed nursing home residents served as ideal population non-confounded exposures. Use surrogate measurements morbidity can trigger worthwhile responses advance laboratory-confirmed diagnosis help reduce total This report describes relative strengths weaknesses these methods for community-wide waterborne illness detection their application outbreak decision making.
