Abstract：
UNASSIGNED: The prevalence of hepatitis B in the Republic of Korea has declined, yet the disease burden persists. After various changes in targets and methods, the national hepatitis B surveillance system now exclusively monitors acute cases. We aimed to assess the alignment of this system with its intended purpose and to recommend improvements supporting the national strategic plan for viral hepatitis management.
UNASSIGNED: This study assessed acute hepatitis B cases reported to the Korean Disease Control and Prevention Agency\'s mandatory surveillance system over a 10-year period (2013-2022). It evaluated 5 factors from the Centers for Disease Control and Prevention\'s Updated Guidelines for Evaluating Public Health Surveillance Systems: simplicity, positive predictive value, data quality, timeliness, and usefulness.
UNASSIGNED: The nonspecific nature of acute hepatitis B symptoms, along with the complexity of diagnostic criteria, indicated a high potential for misreporting. The surveillance system demonstrated a high positive predictive value (94.4%), with data quality and timeliness also rated high. However, data following the onset of the coronavirus disease 2019 pandemic indicate the need for improvement. Moreover, given the relative importance of specific characteristics of chronic infectious diseases, only limited interventions are implementable through the current surveillance system.
UNASSIGNED: The evaluation of the Republic of Korea\'s acute hepatitis B surveillance system revealed high positive predictive value, data quality, and timeliness. However, improvements can be made in the misreporting of chronic cases and the system\'s usefulness. More accurate reflection of the characteristics of acute hepatitis B cases is essential for better management of viral hepatitis.

摘要：
■大韩民国的乙型肝炎患病率有所下降，然而，疾病负担仍然存在。在目标和方法的各种变化之后，国家乙型肝炎监测系统现在专门监测急性病例。我们旨在评估该系统与预期目的的一致性，并建议改进支持国家病毒性肝炎管理战略计划。
■这项研究评估了在10年期间（2013-2022年）向韩国疾病控制和预防机构的强制性监测系统报告的急性乙型肝炎病例。它评估了疾病控制和预防中心更新的公共卫生监测系统评估指南中的5个因素：简单性，正预测值，数据质量，及时性、及时性和有用性。
■急性乙型肝炎症状的非特异性，随着诊断标准的复杂性，表明误报的可能性很高。监测系统显示出较高的阳性预测值(94.4%)，数据质量和及时性也被评为高。然而,2019年冠状病毒病大流行爆发后的数据表明，需要改善。此外，鉴于慢性传染病的特定特征的相对重要性，只有有限的干预措施可以通过当前的监测系统实施。
■对大韩民国急性乙型肝炎监测系统的评估显示出很高的阳性预测值，数据质量，和及时性。然而,可以改善慢性病例的误报和系统的有用性。更准确地反映急性乙型肝炎病例的特征对于更好地管理病毒性肝炎至关重要。
