發(fā)熱呼吸道癥狀監(jiān)測在甲型H1N1流感暴發(fā)早期預警的效果
[Abstract]:Objective to investigate the effect of fever respiratory symptom monitoring in early warning of influenza A H1N1 outbreak. Methods from January 2007 to December 2009, the surveillance data of fever and respiratory symptoms were collected and analyzed, and the data of influenza A (H1N1) outbreak in 2009 were fitted to judge the early warning effect. Results in 2009, the number of H1N1 cases increased significantly after 35 weeks, reached the peak at 42 weeks, and then began to decline. The trend was the same as that of ILI% (the percentage of influenza-like cases to the total number of outpatient and emergency visits) in the same period. Control chart method showed that early warning information appeared in 21 ~ 29 weeks, 35 ~ 43 weeks and 46 weeks in ILI%, which was basically consistent with the trend of A / A H1N1 epidemic in 2009; The moving average regression method showed that ILI% exceeded the average at 2526 weeks, 29 weeks and 36 weeks 42 weeks in 2009, and exceeded the 2.0 standard deviation warning line in the 42nd week of 2009, which coincided with the peak trend of H1N1 A in the 42nd week of 2009. Conclusion the early warning of fever and respiratory symptoms can better reflect the outbreak of influenza A H1N1, and the effect of moving average regression method is better than that of control chart method.
