Analysis on the epidemic status of notifiable communicable diseases before and after the application of the Diseases Surveillance Information Reporting System.

Objective The present study was conducted to compare the reporting situation of no-tifiable communicable diseases before(from 2001 to 2003) and after (2004) the application of the Diseases Surveillance Information Reporting System，with the evaluation of the effects and prob-lems of the system involved．Methods The reported incidences of communicable diseases in 2001，2002，2003，and 2004 were compared．Results A and B communicable diseases were rela-tive stable in Wuhan City from 2001 to 2003，and the difference of the reported incidences had no statistical significance．In 2004，very significant difference of the reported incidences occurred with-out the support of the epidemiological data．Conclusion Great changes had taken place in the reporting mode of the epidemic Status for the change of the reposing system．The failure reports resulted from the medium links decreased and the reported incidences of the communicable dis- eases increased，SO the reported incidences of the communicable diseases rose．Among the commu-nicable diseases，the reported incidences of hepatitis B and pulmonary tuberculosis increased most obviously，which were mainly caused by the repeating and false reporting of the two diseases．The function of checking repetition in the Diseases Surveillance Information Reporting System should be improved at once，the intellectual system to judge the diseases should be added，and the accu-racy of reporting communicable diseases should be enhanced．
