Methods The rate of registering and reporting of communicable diseases and the reporting rates by disease entities and healthcare facilities as well as the timeliness,veracity and integrality of the report cards were all compared between 2002-2003 and 2004-2005. Results The registering and reporting rate of communicable diseases increased after the application of the system,the reporting rates increased most significantly for Hepatitis B and pulmonary tuberculosis and was the lowest for community healthcare service centers. The timeliness,veracity and integrality of the reports showed remarkable improvement. Conclusion The registering and reporting rate of communicable diseases increased after the application of the system. The uncultured prophase of reporting card procedure,survey method of failure to report and sexually transmitted disease management and the low utilization of community healthcare service centers should be altered to accelerate the improvement of the registering and reporting rate.
