Abstract
OBJECTIVES: The important steps in controlling infectious diseases are fast detection, proper treatment and on-time reporting of cases to the appropriate authorities. This study was conducted to evaluate the quality of Iranian communicable diseases surveillance system (CDSS) for zoonotic diseases in rural areas of Fars province (Iran's third largest province). STUDY DESIGN: The three most important evaluation indices of CDSS, namely under-ascertainment, under-reporting and timeliness, for the three most common zoonotic diseases were measured using independent data source obtained from door-to-door interviews and patients' medical records. METHODS: Interviews were conducted with 48,771 households in rural areas of Fars province from April 2014 to March 2015. The medical and registration data were obtained from the CDSS and medical or health centres. RESULTS: Under-ascertainment, total under-reporting and timeliness (delay from the time of onset of symptoms to the time of visiting a medical or health centre, to the time of reporting visited cases to the highest level of CDSS) for leishmaniasis were 19.6%, 42.5% and 81.61 days (48.95 due to system delay), respectively. The corresponding indices for brucellosis were 0%, 41.8% and 56.5 days (22 due to system delay), respectively. For animal bite, the corresponding indices were 7.83%, 13.07% and less than 72 h, respectively (no system delay). CONCLUSIONS: Although the status of case reporting and timeliness of surveillance system in public sectors providing medical services are clearly better than those of the private sectors, the indices are far from the level needed by CDSS to be able to detect and handle epidemics on time. Training health personnel, especially physicians, from public and private sectors to secure their cooperation along with routine and indebt evaluation are necessary to improve CDSS in Iran.
