우리나라 유행성각결막염과 급성출혈성결막염의 유행 및 역학적 특성, 2004-2007

Abstract

Purpose: In order to investigate the epidemic and dynamic characteristics of epidemic keratoconjunctivitis (EKC) and acute hemorrhagic conjunctivitis (AHC), data collected by the Ophthalmologic Sentinel Surveillance System (OSSS) from 2004 to 2007 were analyzed. The OSSS data set for school-age children and adolescents were also compared with data recorded for conjunctivitis by the participating school sentinel surveillance system. Method : In the OSSS, participating ophthalmologic clinics reported cases of EKC and AHC to the Center for Disease Control and Prevention on weekly basis. The data collected from 2004 to 2007 for each disease were analyzed using epidemiologic parameters. These were also compared and examined with the data from the school sentinel surveillance system. Results : The average reporting rate in the OSSS incrementally increased to about 94% in 2007. It was confirmed that most cases of EKC and AHC occurred in late summer, around August and September, exhibiting a seasonal characteristic. Both EKC and AHC showed the highest incidence in the age group of 10-19 year-old school age children and adolescents. Similarly, both occurred remarkably higher in the epidemic period than in the non-epidemic period. Regionally, both EKC and AHC started in southern regions such as Honam and Yeongnam, and then tend to spread to other regions with some exceptions. The point of incidence for conjunctivitis reported in the school sentinel surveillance system was earlier than that reported for the highest incidence in the OSSS. Conclusion : The epidemic and dynamic characteristics of EKC and AHC in Korea were comprehensively analyzed using the data collected by the OSSS from 2004 to 2007. Continuous ophthalmologic surveillance through the OSSS and preventive measures based on the collected data would provide an effective control of EKC and AHC.
