Positive correlation existed between febrile cases and pneumonia cases (r=0.251, P0.05). The proportions of febrile cases in outpatient and emergency departments of Changzhou were lower than those in other southern provinces, the differences were statistically significant. (t=8.937,P0.05; t=10.655,P0.05). Conclusion The surveillance of febrile respiratory illness and pneumonia is a long-term and consecutive work and should be integrated into the surveillance system for influenza and public health emergency.
